Cardiovascular System: Heart Function

This lecture covers the properties of cardiac fibers, the generation of the electrical signal for cardiac pumping, the electromechanical coupling in cardiac muscle, and the cardiac cycle during systole and diastole. It also explains the source of the cardiac rhythm at three levels, provides an example of a normal ECG trace, and discusses the properties of veins. The lecture delves into the comparison of muscle structure and function between skeletal, cardiac, and smooth muscle, as well as the general mechanism of blood distribution in the body.
