About Human Heart
The human heart is a four chambered muscular pump that maintains double circulation through the pulmonary and systemic circuits. Questions cover atria, ventricles, valves, major blood vessels, the cardiac cycle, pressure changes, the conduction system and ECG, while distinguishing arteries and veins from the chambers that receive or eject blood.
