#HeartPhysiology #HeartAnatomy #HumanHeart Human Heart Structure and Function The heart is a muscular organ about the size of a fist, located just behind and slightly left of the breastbone named sternum. The human heart pumps blood throughout the body via circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes. • The heart consists of four chambers, Two chambers are located in the upper portion of the heart called atria which consist of right and left atrium. While the two chambers are located in the lower portion of the heart called right and left ventricles. • The right atrium receives deoxygenated blood from the veins and pumps it to the right ventricle. • The right ventricle receives that blood from the right atrium and pumps it to the lungs, where it is loaded with oxygen. • The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle. • The left ventricle pumps oxygen-rich blood to the rest of the body. Each chamber of the heart is separated by valves that only permit blood to flow in one direction. The tricuspid valve is located between the right atrium and right ventricle and opens due to a build-up of pressure in the right atrium. The bicuspid valve is located between the left atrium and left ventricle and likewise opens due to a build-up of pressure in the left atrium. The semilunar valves stop the back flow of blood into the heart. There is a semilunar valve where the aorta leaves the left ventricle and another where the pulmonary artery leaves the right ventricle. The right-hand and left-hand side of the heart is separated by muscular wall called septum. The septum prevents the mixing of oxygenated and deoxygenated blood. The heart pumps blood through the network of arteries and veins called blood vessels. The vessels that bring blood to the heart are called veins, while the vessels that carry blood away from the heart to other regions of the body are called arteries. There are four main blood vessels that take blood into and out of the heart. 1. the aorta is the largest artery in the body. It carries oxygenated blood away from the left ventricle to the body 2. the vena cava is the largest vein in the body. It carries deoxygenated blood from the body back to the heart 3. the pulmonary artery carries deoxygenated blood away from the right ventricle to the lungs 4. the pulmonary vein returns oxygenated blood from the lungs to the heart

#CoronaryArteryDisease #HeartAttack #HeartDisease Coronary artery disease The coronary arteries are the blood vessels that carry blood to your heart. Through blood, these arteries supply oxygen and nutrients to your heart. Coronary artery disease is the narrowing or blockage of these coronary arteries. This condition is usually caused by atherosclerosis. Atherosclerosis is the buildup of fats, cholesterol, and other substances in your artery walls. This buildup is called plaque. Your arteries become narrow as a result of the plaque, preventing blood flow. And If the heart does not get enough blood, it cannot get the oxygen and nutrients it needs to work properly. This can cause chest pain (angina) or a heart attack. Let us see that how does plaque build-up in the arteries? Healthy coronary arteries are smooth and elastic. Coronary artery disease is thought to begin with damage or injury to the inner layer of a coronary artery. The damage may be caused by various factors, including: • Smoking • High blood pressure • High cholesterol • Diabetes • Aging and Not being active. Because of these risk factors, Coronary artery disease starts by the builds up of fat, causing minor damage to your blood vessel walls. With time, other substances that move through your bloodstream, such as inflammatory cells, cellular waste products, proteins, and calcium, stick to the vessel walls. These things combine with the fat and form plaque. If your coronary arteries narrow, they can't supply enough oxygen-rich blood to your heart — especially when it's beating hard, such as during exercise leading to a chest pain called Angina. And sometimes the plaque surface breaks or ruptures, and blood cells called platelets clump together at the site to try to repair the artery. This clump can block the artery, leading to a heart attack. Symptoms If your coronary arteries narrow, they can't supply enough oxygen-rich blood to your heart. At first, the decreased blood flow may not cause any symptoms. however, as plaque continues to build up in your coronary arteries, you may experience the following signs and symptoms of coronary artery disease. • Chest pain (angina). You may feel pressure or tightness in your chest as if someone was standing on your chest. This pain is called angina. It usually occurs on the middle or left side of the chest. Angina is generally triggered by physical or emotional stress. The pain usually goes away within minutes after stopping the stressful activity • Shortness of breath. If your heart can't pump enough blood to meet your body's needs, you may develop shortness of breath or extreme fatigue with activity. • Heart attack. A completely blocked coronary artery will cause a heart attack. The classic signs and symptoms of a heart attack include crushing pressure in your chest and pain in your shoulder or arm, sometimes with shortness of breath and sweating. Prevention Coronary artery disease is treated with lifestyle changes. A healthy lifestyle can help keep your arteries strong and clear of plaque. To improve your heart health, follow these tips: • Quit smoking. • Maintain blood pressure, cholesterol, and diabetes under control. • Stay physically active. • Eat a low-fat, low-salt diet that's rich in fruits, vegetables, and whole grains. • Maintain a healthy weight. • Reduce and manage stress. _______________________________________________________________________________________ #CoronaryArteryDisease #HeartAttack #HeartDisease human heart disease coronary disease blockage in heart blockage in heart blood vessels coronary artery disease treatment, coronary artery disease risk factors, coronary artery disease animation

#fundoplication Welcome yo our channel demystifying science. In this video you will learn about a special medical procedure userd to treat acid reflux or GERD called Fundoplication. Fundoplication procedure Many people experience complaints of burning sensations in their lives due to acid reflux. The condition occurs when the sphincter valve at the end of our esophagus, just before the stomach, doesn't function properly. When we eat, food travels from our mouth and esophagus to our stomach. Once food enters the stomach, the sphincter valve closes, preventing the backward movement of food from the stomach to the esophagus during digestion. However, sometimes the valve fails to close properly, allowing stomach acid to enter the esophagus, leading to the condition known as acid reflux. It's important to note that while everyone may experience acid reflux at some point, if this condition becomes recurrent immediately after eating, it is referred to as GERD, or gastroesophageal reflux disease. In patients with GERD, frequent acid reflux can cause damage to the cells in the walls of the esophagus, leading to inflammation known as esophagitis. If GERD is not treated promptly, it may even lead to esophageal cancer. Therefore, doctors often treat GERD with medications, but if medications are not effective, they may suggest a specific procedure called fundoplication. Now, let's understand how the fundoplication procedure is performed. Fundoplication, also known as Nissen fundoplication, is a small surgical procedure that can be performed in two different ways: laparoscopic fundoplication and open fundoplication. Before performing the fundoplication procedure, doctors conduct a detailed examination of the patient's stomach using gastrointestinal X-rays, esophageal manometry (which measures pressure in the esophagus), and endoscopy. Approximately 22-24 hours before the procedure, patients are usually instructed not to eat or drink anything. In laparoscopic fundoplication, the surgeon administers local anesthesia to the patient and numbs the surgical site. Then, a small incision is made in the abdominal region, and a laparoscope, a device with a camera at its front, is inserted through the cut. The surgeon uses instruments to wrap the upper portion of the stomach around the lower portion of the esophagus and closes the wound with stitches. In contrast, open fundoplication involves the surgeon administering general anesthesia to the patient, making a large incision in the abdominal region, exposing the stomach, and wrapping the upper portion of the stomach around the lower portion of the esophagus. The wound is then closed with stitches. After the fundoplication procedure, patients may experience a sore throat for 1-2 days. They are often given fluids through a vein for nutrition, and a tube is passed into the stomach to remove gastric juices. Patients are usually advised to refrain from eating until they have bowel movements or pass gas, indicating that their body is returning to normal functioning. Thanks For Watching. #fundoplication

#HearingLoss #Earbuds #CochleaDamage Earbuds are basically a pair of tiny speakers that you wear inside your ears. And loud music playing that close to your eardrum can cause permanent hearing loss. So let us see that How Earbuds can Damage the Ears The ear is made up of three parts that work together to process sounds: the outer ear, the middle ear, and the inner ear. Part of the inner ear called the cochlea contains tiny hair cells. These hair cells help send sound messages to the brain. But loud noise can damage the hair cells. A small amount of damage will have little effect on your hearing. But repeated exposure to loud noise will continue to damage these hair cells, and eventually, the cochlea can’t relay sound messages to the brain. The human ear can safely listen to sounds up to 70 decibels (dB). An MP3 player at 70% of its top volume is about 85 decibels. Turning the volume up and listening for long periods of time can put you in real danger of permanent hearing loss. Beside this earbuds can also cause ear infection by creating favorable environment for bacteria and fungi. During earbuds put on the air cannot enter inside ear hence the ear canal remain moist which promotes bacterial growth. So how we can use Use Earbuds the Right Way?  Listen to the music at no more than 60% of the maximum volume.  Limit the amount of time you spend with earbuds in your ears to 60 minutes.  Or simply Use Headphones Instead of Earbuds.

#Tonsillectomy Tonsillectomy is a surgical procedure performed to remove the tonsils. Tonsils are two round-shaped lymphoid organs located in our throat that function to trap and kill bacteria, viruses, and other foreign particles that enter our mouth. Sometimes, our tonsils can also accumulate food particles, mucus, and other debris, leading to inflammation and the formation of tonsil stones. This can result in symptoms such as bad breath, severe throat pain, coughing, swelling, fever, and, in some cases, sleeping disorders. In such conditions, it becomes necessary to remove the tonsils, and doctors recommend tonsillectomy surgery. Before the surgery, patients undergo various tests, and they are instructed to avoid taking any medications or eating/drinking anything. During the surgery, patients are put under anesthesia, and tonsils are removed using either electrocautery or cold knife dissection procedures. In electrocautery, the surgeon uses heat to remove the tonsils and stop bleeding, while in cold knife dissection, a surgical knife is used to remove the tonsils, followed by the use of electrocautery to control bleeding. In some cases, surgeons may use a special surgical instrument called a "snare" for tonsillectomy. The snare has a thin wire loop at its end, which is used to grab the tonsils during the procedure to minimize bleeding. Additionally, tonsils can also be removed using techniques such as radiofrequency ablation, carbon dioxide lasers, or microdebriders. Tonsillectomy is an outpatient procedure that typically takes 20 to 30 minutes to complete. After the surgery, patients are transferred to the recovery room, where they regain consciousness, and after a few hours of hospital stay, they are discharged. #Tonsillectomy #TonsilsRemoval

In the term angioplasty, “angio” means blood vessel, and “plasty” is opening up. An angioplasty is a surgical procedure to open the blood vessels that supply blood to your heart muscle. These blood vessels are known as coronary arteries. Angioplasty is a conventional treatment for coronary artery disease (CAD) and heart attacks. In these conditions, there is a buildup of plaque, or atherosclerosis, on the walls of the arteries. As plaque accumulates, the arteries narrow and can become blocked. In a heart attack, the plaque may rupture, leading to a clot that stops blood flow. Doctors perform more than 1.8 million angioplasties a year in the United States, according to the American College of Cardiology. Let us see how angioplasty is performed Before beginning angioplasty, a healthcare professional will clean and numb the area where the catheter enters the body, usually the groin but sometimes the wrist. Next, a doctor inserts the catheter into the artery and directs it towards the coronary artery, watching its progress on an X-ray feed. Once the catheter is in position, the doctor injects a contrast dye through the artery, which helps identify blockages around the heart. This process is called angiography. Once they locate the blockages, the doctor inserts a second catheter and a guidewire, usually with a balloon at the tip. When the second catheter is in position, the doctor inflates the balloon by which the fatty deposits, or plaque, get pushed against the wall of the artery. This clears the way for blood flow. In some cases, the catheter is also equipped with a stainless steel mesh called a stent. Most people who have an angioplasty also have a stent placed in their blocked artery during the same procedure. A stent, which looks like a tiny coil of wire mesh, supports the walls of your artery and helps prevent it from re-narrowing after the angioplasty. Here's what happens during a stent placement:  The stent, which is collapsed around a balloon at the tip of the catheter, is guided through the artery to the blockage.  At the blockage, the balloon is inflated and the spring-like stent expands and locks into place inside the artery.  The stent stays in the artery permanently to hold it open and improve blood flow to your heart. In some cases, more than one stent may be needed to open a blockage.  Once the stent is in place, the balloon catheter is deflated and removed.  More X-ray images (angiograms) are taken to see how well blood flows through your newly widened artery. Most stents implanted during an angioplasty are drug coated. The medication in the stent is slowly released to help prevent future plaque buildup and the re-narrowing of the blood vessel. Recovery When angioplasty is completed, the cardiologist removes the catheters and bandages. #Angioplasty #Angiography

Hey there, YouTube viewers! Welcome back to another informative video on brain health. Today, we're diving deep into the world of brain tumors and the cutting-edge treatment methods that are changing lives. 🧠💪 Imagine this: your brain, that incredible powerhouse, sometimes faces its own battles in the form of abnormal cell growth. That's where brain tumors come into play. These growths can happen due to various factors like exposure to radiation or hereditary issues passed down from generation to generation. But fear not, because modern medicine has some impressive tricks up its sleeve to tackle these challenges head-on. Let's talk treatment methods! First up, we've got the number one player in the game: Craniotomy. Yep, you heard that right. It's the most commonly performed surgery for brain tumors. Skilled neurosurgeons use high-tech tools and medical wizardry to locate the precise position of the tumor. Then, they work their magic by making a small incision in your scalp and carefully removing a section of the skull to access the brain. With the help of cutting-edge technology like the tubular retractor system, they navigate through the delicate brain matter, ensuring minimal damage while getting rid of that troublesome tumor. This technique isn't just about brain tumors, though—it's also used to tackle blood clots and skull fractures. Talk about multi-tasking! Now, let's shine a spotlight on Neuroendoscopy, our number two contender. Imagine this as a strategic mission with a few small holes in your skull as the entry points. Skilled surgeons use a neuroendoscope—a fancy tool with a camera—to zoom in on the tumor and remove it with precision. This method is particularly handy for those tricky-to-reach tumors like pituitary or pineal tumors. And guess what? Sometimes they take the scenic route through your nose or mouth to get to those stubborn growths. Now that's some out-of-the-box thinking! And then we have Laser Ablation, the futuristic warrior in this battle. Imagine a thin laser probe sneaking into your brain, using light and heat to locate and zap away the tumor. It's like something out of a sci-fi movie, but it's real, and it's making waves in the medical world. In a nutshell, brain tumors might be serious business, but thanks to these advanced surgical techniques, there's a light at the end of the tunnel. Success stories hinge on early diagnosis and the tumor's nature, so stay informed, stay vigilant. With medical technology evolving at lightning speed, there's hope for those dealing with this condition. Whether it's craniotomy, neuroendoscopy, or laser ablation, the future looks promising for brain tumor removal surgery. Thanks for tuning in, folks!

#gingivitis #toothloss Welcome to our channel Power of knowledge. In this video you will learn about a medical condition called Periodontitis with the help of 3d animations. Periodontitis, also known as Gum disease, is a dental condition where the bones surrounding the teeth get damaged, causing the teeth to loosen and eventually fall out. This disease affects nearly every other person over 30 years old and progressively weakens teeth due to aging. Let's take a closer look at what Periodontitis involves and how it impacts our teeth. Our teeth are divided into two parts: the visible upper part called the Crown, followed by the root hidden in our gums. The root of the tooth, is tightly connected to the bone by periodontal ligaments, providing strength to our teeth and preventing them from wobbling while chewing. However, if you don't clean your teeth properly, a layer forms on them consisting of bacteria, proteins from saliva, and dead cells, known as plaque. Bacteria within plaque gradually spread beneath your gums. Once the plaque layer extends beneath the gum line, it cannot be cleaned effectively with normal brushing, allowing bacteria to further grow. These bacteria accumulate, forming a harder and darker layer called tartar or calculus. Different types of bacteria start growing in the calculus layer, disturbing our gums, leading to bleeding, swelling, or looseness. This stage is termed gingivitis, indicating inflammation of the gums. At this point, the condition can still be treated as it hasn't caused damage to your teeth or jawbone. However, if left untreated, the bacteria move deeper, damaging the bone around the tooth socket. This triggers immune cells to reach the infection site, attempting to kill the bacteria, but some bacteria can evade immune cells and worsen the bone destruction process. Gradually, the bone surrounding the teeth weakens, gums become loose, and teeth start loosening. This stage is termed periodontitis. Symptoms: Symptoms of Periodontitis include swollen gums, bleeding gums, loose gums, bad breath, darkening of gums, and more. Treatment: Detecting and treating Periodontitis in its initial stages is possible, but once it progresses to bone destruction, it becomes challenging to treat. Surgical methods and techniques can be used to some extent to treat this condition, which we'll discuss in our upcoming videos. Thanks For watching. #toothloss #gingivitis

#naegleriafowleri #naegleria Naegleria, also known as brain-eating amoeba, is a type of parasite that enters our brain and starts consuming our brain cells. After entering the brain, the chances of a person surviving are very low. In the United States, out of 157 reported cases of Naegleria infection, only 4 patients have survived. Based on this data, the death rate of Naegleria infection is estimated to be 97%. Now, let's see why and how Naegleria infection occurs. Naegleria is a free-living amoeba that mostly resides in warm freshwater environments, such as rivers, ponds, and water tanks. When we swim or perform ablution (wudu) in such water, the amoeba can enter our nasal passage. Inside our nose, we have olfactory nerves that provide us with the sense of smell. The amoeba uses these nerves to enter the brain and cause an infection, known as Primary Amebic Meningoencephalitis (PAM). Symptoms of Naegleria infection include headaches, fever, and vomiting. As the amoeba continues to damage brain cells, the symptoms worsen, and the infected person experiences stiffness in the neck, becomes sensitive to light, and eventually falls into a coma, where chances of survival are slim. As of now, there is no specific treatment for Naegleria infection, and the amoeba is usually found in low quantities in water. However, it is advisable to avoid swimming in warm freshwater during the summer, as once the parasite enters the brain, survival becomes extremely difficult due to the lack of effective treatment. To prevent Naegleria infection, avoid swimming in rivers and ponds and use chlorine or salt in water tanks for ablution. It's important to note that Naegleria does not enter the brain through drinking water, and it is not transmitted from one person to another. Thank you. #naegleriafowleri #naegleria

#weightloss #weightlosssurgery Welcome to our youtube channel Power of knowledge. In this video you will learn about Gastric Balloon surgery. The gastric balloon, also known as the endoscopic intragastric balloon, is a non-surgical weight-loss method. It involves placing a special balloon in your stomach to take up space and reduce how much food your stomach can hold. This helps you feel full faster and eat smaller portions. The balloon is temporary and usually removed after about 6 months. This procedure is mainly recommended for people with obesity. Procedure: The gastric balloon is placed in an outpatient procedure. It's done using an endoscope, a thin tube with a camera, while you're sedated. The deflated balloon is attached to the endoscope and guided into your stomach. Once in the right place, the doctor fills the balloon with saline, dye, or gas to the needed size. After the endoscope is taken out, the balloon stays in your stomach. This process takes around 15 minutes, and you can leave the hospital shortly after. The balloon stays in your stomach for about 6 months, and then it's taken out, also while you're under sedation. After Procedure: After the procedure, your throat might be a bit sore, and you might feel some cramps and nausea as your stomach adjusts. You'll have a liquid or soft diet for a few weeks, followed by 6 months of supervised diet and behavior changes. Risk: The procedure is usually safe, but there might be rare complications like ulcers or balloon deflation. If the balloon breaks, the dye might show up in your urine, so inform your doctor right away. Conclusion: Gastric balloon is a low-risk way to help lose weight and improve conditions like type 2 diabetes, sleep apnea, high blood pressure, and heart disease. If you're worried, talk to your doctor. Thanks for Watching #weightloss #weightlosssurgery

#Acne #Pimples pimples are reddish papule in our skin made up of pus pimples are formed due to blockage in sebaceous glands and infection sebaceous glands are special gland in our skin that secrete an oily substance called sebum after secretion sebum is released into the skin through hair pores and lubricates our skin due to which our skin doesn't dry and rough in some cases, if sebum is secreted more , than there will be a chances of blockage in hair pores due to which sebum doesn't come out of skin and starts to collect inside skin the collection of sebum inside skin creates favorable environment for the growth of some bacteria's and they grow very fast and cause infection due to the growth of bacteria, our immune system activates due to which white blood cells come together to infection site to fight with bacteria white blood cells starts eating bacteria and dead skin cells due to which inflammation starts and pus is formed and we can see pus in the form of pimples in most cases pimples develops on face this is because there are more sebaceous glands on our face pimples can formed at any age but in most cases pimples are formed during puberty and menstrual cycle in females. this is because of hormonal changes in human body due to which sebaceous glands become overactive and starts secreting more sebum beside this, people having oily skin or people with hot and unhealthy diet have more chances of pimples to reduce pimples, maintain healthy diet and concern with skin specialist (Dermatologist) to treat pimples #Pimples #Acne

Coronary bypass surgery redirects blood around a section of a blocked or partially blocked artery in your heart. The procedure involves taking a healthy blood vessel from your leg, arm or chest and connecting it below and above the blocked arteries in your heart. With a new pathway, blood flow to the heart muscle improves. Coronary bypass surgery doesn't cure the heart disease that caused the blockages, such as atherosclerosis or coronary artery disease. However, it can ease symptoms, such as chest pain and shortness of breath. For some people, this procedure can improve heart function and reduce the risk of dying of heart. Watch Video For More

#EyeSurgery #Lasik #LaserEyeSurgery LASIK eye surgery is the best known and most commonly performed laser refractive surgery to correct vision problems. Laser-assisted in situ keratomileusis (LASIK) can be an alternative to glasses or contact lenses. During LASIK surgery, a special type of cutting laser is used to precisely change the shape of the dome-shaped clear tissue at the front of your eye (cornea) to improve vision. In eyes with normal vision, the cornea bends (refracts) light precisely onto the retina at the back of the eye. But with nearsightedness (myopia), farsightedness (hyperopia) or astigmatism, the light is bent incorrectly, resulting in blurred vision. #LaserEyeSurgery #Lasik #EyeSurgery

Bone Fracture Basics There are several types of bone fractures, and each type can have slight variations. 1. Transverse Fracture Transverse fractures are breaks that are in a straight line across the bone. 2. Open compound Fracture A fracture in which the bone breaks through the skin and can be seen outside the leg. 3. Oblique Fracture An oblique fracture is when the break is diagonal across the bone. 4. Comminuted Fracture A comminuted fracture is one in which the bone is broken into 3 or more pieces. 5. Segmental Fracture The same bone is fractured in two places, leaving a “floating” segment of bone between the two breaks. 6. Greenstick Fracture This is a partial fracture that occurs mostly in children. The bone bends and breaks but does not separate into two separate pieces. Children are most likely to experience this type of fracture because their bones are softer and more flexible. 7. Spiral Fracture As the name suggests, this is a kind of fracture that spirals around the bone. 8. Avulsion Fracture An avulsion fracture occurs when a fragment is pulled off the bone by a tendon or ligament.

Cardiopulmonary resuscitation (CPR) is a life-saving method that can be used in a variety of situations where someone's breathing or heartbeat has stopped, such as a heart attack or near drowning. CPR Procedures: Use CPR if an adult is not breathing or is only gasping infrequently, and if they are not responding to questions or taps on the shoulder. When children and infants are not breathing regularly and are not reacting, use CPR. check that the area is safe, then perform the following basic CPR steps: 1. Call 911 or ask someone else to. 2. Lay the person on their back and open their airway. 3. Check for breathing. If they are not breathing, start CPR. 4. Perform 30 chest compressions. 5. Perform two rescue breaths. 6. Repeat until an ambulance or automated external defibrillator (AED) arrives. #CPR #CprInAction, #CardiopulmonaryResuscitation, #CardiacArrestEmergency
