Physiology: The Cardiovascular System
How the heart generates its own rhythm, how it fills and ejects, and how the circulation keeps pressure and flow matched to demand. Animated lessons cover the cardiac action potential and the cardiac cycle; written notes carry the numbers and graphs examiners ask for.
