What is the function (physiology) of cardiovascular system.?

The primary function of the cardiovascular system is to transport blood throughout the body to supply tissues with oxygen and nutrients and remove waste products.

- Oxygen and nutrient delivery: The heart pumps oxygenated blood through the arteries to deliver oxygen and nutrients to tissues in the body.

- Waste product removal: The cardiovascular system also collects waste products like carbon dioxide and carries them back to the lungs and kidneys for elimination.

The cardiovascular system has several components:

- Heart: A muscular organ responsible for pumping blood.

- Blood vessels: Arteries, capillaries, and veins through which blood flows.

- Blood: Fluid that contain red blood cells, white blood cells, platelets, and plasma

The cardiovascular system consists of two circuits: pulmonary and systemic.

. Pulmonary Circulation:

- Transports blood ( deoxygenated blood) from the heart to the lungs and back for gas exchange

. Systemic Circulation.

- Pumps oxygenated blood from the heart throughout the body tissues and then back to the heart, to start the pulmonary circulation all over again.
