Cardiac System: From Stimuli to Rhythmic Muscle Contraction - Part 3

This lecture explores the cardiac cycle and blood pressure changes, explaining how the heart generates force through its valves and electrical system. Learn about the pacemaker function, systolic and diastolic pressure, blood volume regulation, and blood flow throughout the body. Examine the heart's non-conducting fibrous system, the sinoatrial (SA) node's role as the natural pacemaker, associated ion changes, and the function of artificial pacemakers.
