About Cardiovascular System
The cardiovascular system covers the chambers, valves and major vessels of the heart, the cardiac cycle, conduction pathway, blood pressure and the circulation through pulmonary and systemic circuits. It also explains artery, vein and capillary structure, exchange at capillary beds, and how the cardiac cycle differs from general blood flow.
