The course builds upon your primary knowledge of the heart and circulation.

Essential aspects of cardiac and vascular physiology will be considered.

The oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle.

This blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle.

This will enable you to grasp a number of areas of experimental, applied and patho-physiology.

to: - provide contemporary views on cardiac and vascular function; - relate this knowledge to the human subject; - link the treatment of cardiovascular disease to basic mechanisms; - help you develop independent study skills and teamwork; - facilitate the development of your written and oral communication skills.

However, despite their knowledge of the heartbeat, vessels, and pulse, the Egyptians attributed the movement of substances throughout the vessels to air that resided in these channels, rather than to the heart's force.

The Egyptians knew that air played an important role in circulation, but they did not yet have a concept for the precise role of the lungs.

Blood is then pumped from the right ventricle through the pulmonary valve and into the main pulmonary artery.

The pulmonary arteries carry deoxygenated blood to the lungs, where carbon dioxide is released and oxygen is picked up during respiration.
