This lesson describes the energy molecules of carbohydrate and fat and how they are used in the body.

This lesson discusses the neuron, synapse and neurotransmitters, and gives examples of medications and diseases that affect their function.

This video discusses the anatomy of the heart in particular the 4 valves. These flaps of tissue prevent blood from flowing backward. The valves are located between the atria and the ventricles, and also leading from the heart.

Describes how we transfer energy from one animal or plant to another. Also discusses the gastrointestinal tract and its role in the break down and transport of triglycerides and fat via the bowel, portal vein, liver and fat cells. Finally, the video provides an explanation of a high serum triglyceride level and its effect on health.

This lesson describes the basic physics of Nuclear Magnetic Resonance and relevant terms such as T1 & T2 relaxation, pulse sequence, frequency and phase encoding, T1WI and T2WI. Introduces the landmark papers of Drs. Damadian and Lauterbur that made magnetic resonance imaging a reality.

Describes the basic biochemistry of the energy storing molecule, the free fatty acid and it's storage form in plants and animals, the triglyceride.

Blood flows throughout the body via blood vessels. These are the tubes that form a closed pipeline within the body. There are three types of vessels and this video discusses their structure and function.

This video considers blood pressure. When ventricles contract, they increase pressure on the blood. The resulting force that blood exerts against the artery walls is called blood pressure.

This video shows the process of vascular degneration starting with intimal trauma, fatty streaking and plaque formation which can lead to leg pain (claudication), heart attack and stroke.

If you could peer into the arteries of a newborn baby, you would probably see fairly smooth blood vessels. If you could inspect the arteries of an older person, you might find plaque. This video looks at atherosclerosis and heart attacks. It also discusses treatments such as balloon angioplasty. https://www.youtube.com/watch?v=Mg0VXYFI9zs&feature=youtu.be

This lesson will look at the History and physics of the CT scanner

This lesson will discuss Varicose veins: What are they, how do we get them and how are they treated?
