Interactive Biology

In this video, we look at the pilot episode of the good doctor and explain the biology behind the scenes. You'll learn about some of the blood vessels leading from the head to the heart (internal and external jugular veins, subclavian vein, and brachiocephalic vein) pericardial effusions, as well as how even a tiny thing can result in serious problems in the human body and the circulatory system. Enjoy. Part 1 - https://youtu.be/etcK4vsqh9Q

In this popular episode of the Good Doctor, a guy falls and hits his head. His head bleeds A LOT. I explain the biology behind that.

In this video, we learn from dr. Shaun Murphy (the Good Doctor) that if there's an increase in intrathoracic pressure, that can affect the heart negatively.

Let's check out this episode and learn a bit about the EKG and Intrathoracic Pressure.

Let's watch this episode of the Good Doctor and learn a little bit about the trachea and how it's a bad thing to put too much pressure on it.

If you want to know how well your kidneys function, a good metric to look at would be the Glomerular Filtration Rate. The Glomerular Filtration Rate is not constant. It needs to be increased or decreased depending on how much the kidney needs to get rid of. Well, how do you affect the glomerular filtration rate? In this video, you will get the answers. Enjoy!

In this pilot episode of The Good Doctor, we learn about the respiratory system as well as the cardiovascular system. We explore topics like what happens when their damage to the internal jugular vein as well as with a tension pneumothorax. I explain how increased intrathoracic pressure can lead to venous distension and how a DIY one-way valve can relieve the intrathoracic pressure that results from a tension pneumothorax. If that seemed like a different language, go ahead and watch the video. It'll all make sense then ;) Timestamps: 00:00 Intro 00:35 Setting the scene 01:14 Jugular Vein cut 02:16 Doctor makes mistake 03:00 Pressure on Trachea 03:37 Glass in abdominal region 03:55 The Dance/Show intro 04:05 Increased Intrathoracic Pressue 04:30 Intrathoracic Pressure and Venous Distension 06:17 Getting the knife 07:40 Making the one-way valve 08:36 Tension Pneumothorax Explained 09:47 The Surgery - Part 2 10:40 The Surgery explanation

The nephron is the functional unit of the kidney. In this video, I talk about the nephron's structure and function. The urinary system is involved in maintaining homeostasis in the body. The bulk of the processing happens in the kidneys, but to understand how the kidneys work, you have to understand the structure and function of the nephrons.

An Interactive Biology First - Today, I share the biology behind one of the most popular episodes of The Good Doctor. Some of the topics covered are the meninges surrounding the brain - the pia mater, arachnoid mater, and dura mater. We also talk about a major blood vessel and how a specific disease affects not just that vessel and one of the meninges. But to understand the biology behind all of it, go ahead and watch the video. Also, let me know which episode you'd like me to dissect in the future.

The kidney filters the blood. And in this video, I show how the blood gets to the kidneys, through the kidneys, and away from the kidneys. The pathway we explore starts with the Abdominal aorta, then to the renal artery, segmental artery, interlobar artery, arcuate artery, interlobular artery, and to the arcuate artery, to the glomerulus, efferent artery, and to the peritubular capillaries. From there, it goes via the interlobular vein, to the arcuate vein, to the interlobar vein to the renal veins, and ultimately via the Inferior vena cava to the heart.

In this lesson, we're looking at the anatomy and physiology of the kidneys. By the end, you will have a good understanding of the structure and function of the kidney. With the anatomy, we get into the three main parts of the kidney: The cortex, medulla, and pelvis as well as recap the concepts of filtration, reabsorption, secretion, and elimination. We also talk about the nephron as the functional unit of the kidney and give an introduction to its blood supply.

The Urinary System is a system that is partially responsible for maintaining homeostasis. Before we can understand the function of the Urinary system, let's set the foundation. In this video, I cover the structure and function of the urinary system. We cover the kidneys, ureters, bladder, and urethra. I also go into the processes of filtration, reabsorption, secretion, and elimination to provide insight into the production of urine. https://www.interactive-biology.com

There are huge things happening in the world of Interactive Biology. If you've ever been a fan (or if you love biology), tune in. Hope to see you live!

http://www.interactive-biology.com - This is an answer to a question that was asked when I did my Anatomy & Physiology Academy on how exactly resistance works when it comes to blood flow. In this video, I explain peripheral resistance in a bit more detail and how there are different factors that are involved in increasing or decreasing Peripheral Reistance

http://www.interactive-biology.com - How is Blood pressure regulated? How do cardiac output and peripheral resistance fit into the equation? What are the negative effects of hypertension (high blood pressure). I explore these concepts and more in this video

http://www.interactive-biology.com - In this video, I start talking about what happens when things go wrong with the cardiovascular system. We start with a general review of the cardiovascular system, starting with the absorption of nutrients into the blood all the way to the function of the heart. We then deal with topics like edema, ischemia, infarctions and how the disfunction of the circulatory system can result in significant problems.

http://www.interactive-biology.com - In this video, I go into the detailed anatomy of the human heart, from the four chambers to the valves to the major arteries and veins, the interatrial and interventricular septa to the lesser known chordae tendinae and papillary muscles. Enjoy!

http://www.interactive-biology.com - As of yesterday, I was officially accepted to go to Khan Academy to work on creating new content for them. I'm not the only one who's excited!

In this video, the motion of finger flexion is occurring at the metacarpophalangeal (MCP) and interphalangeal (IP) joints while squeezing the ball. This motion is controlled by concentric muscle contraction against the resistance from the ball. Concentric metacarpophalangeal (MCP) and interphalangeal (IP) joint flexion is demonstrated from a position of 90⁰ of elbow flexion as seen from a front or anterior view.

In this video, the motion of finger extension is occurring at the metacarpophalangeal (MCP) and interphalangeal (IP) joints. This motion is controlled by eccentric muscle contraction against the resistance from an elastic band. Eccentric metacarpophalangeal and interphalangeal joint extension is demonstrated from a fully flexed hand position as seen from a front or anterior view.
