cardiovascular physiology

Cardiovascular physiology is the study of how the heart and blood vessels work together to circulate blood throughout the body. The heart acts as a pump, sending oxygen-rich blood to organs and tissues while returning oxygen-poor blood to the lungs for rejuvenation. This process is vital for delivering nutrients and removing waste. Blood vessels include arteries, veins, and capillaries, each contributing to this circulation. The system is regulated by electrical signals that coordinate heartbeats and blood pressure, ensuring efficient blood flow, which is crucial for overall health and function.
