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 lecture, I first deal with the functions of the digestive system. We then take a journey through the digestive system by following your food from your mouth all the way through your body and even through the elimination of waste. I also talk about enzymes like amylase in the saliva, pepsin in the stomach and bile from the liver and how those enzymes help in the process of digestion. So go ahead and join me on this journey through the digestive tract. http://www.interactive-biology.com

http://www.interactive-biology.com/ - In this lecture, I discuss the endocrine system and how endocrine glands control functions in the body through the release of hormones. The pituitary gland is known as the Master Endocrine Gland and plays a major role in controlling the other glands of the endocrine system.

http://www.interactive-biology.com/ - In this lecture, I talk about nutrition, starting with the 6 vital nutrients and where you ind them and how your body deals with those nutrients. I end the section by talking about Calories and metabolism. What determines how many calories we need on a daily basis? Watch the video to find out. http://www.interactive-biology.com

http://www.interactive-biology.com - In this lecture, I talk about Cellular respiration, which consists of Glycolysis, the Krebs Cycle and the Electron Transport Chain. I deal with how Glucose is broken down and how ATP is made. Since energy is important for all living things, it's important to understand how ATP, the energy currency of the body, works. http://www.interactive-biology.com

http://www.interactive-biology.com - In this section, I talk about the properties of water, and what makes it unique. I talk about hydrogen bonds that result from the polar nature of water and why ice floats. I also deal with diffusion and go into the 3 factors that affect diffusion: Concentration, Temperature and Pressure. http://www.interactive-biology.com

http://www.interactive-biology.com - In this section, I talk about elements, atoms and how they interact. I deal with two types of bonds: Covalent Bonds and Ionic Bonds. I also talk about pH, chemical reactions and metabolism. http://www.interactive-biology.com

http://www.interactive-biology.com - In this lecture, I introduce the topic of biodiversity, and talk about why biodiversity is important. I end the section talking about threats to biodiversity. Things like Habitat loss, habitat fragmentation and habitat degradation. http://www.interactive-biology.com

http://www.interactive-biology.com - Photosynthesis is the process that plants use to convert energy from the Sun into food. In this lecture, I talk about the process of photosynthesis, and show the steps involved in producing glucose. I go into the Light dependent and Light independent reactions, and show animations that illustrates how those processes happen. http://www.interactive-biology.com
