Cardiovascular system



The basic function of the cardiovascular system is to bring nourishing material and oxygen to the cells. The circulatory system is a closed system, without communication with the outside, consisting of tubes, which are called vessels, and a percussion pump that has the function of driving a circulating fluid of red color throughout the vascular network.

Arterial and Venous SystemThe cardiovascular system consists of the Blood, at the Heart it is us Blood vessels. In order for blood to reach body cells and exchange materials with them, it must be constantly propelled along the blood vessels. The heart is the pump that promotes the circulation of blood through about 100,000 kilometers of blood vessels.

Pulmonary and Systemic Circulation:

Pulmonary Circulation & #8211; It takes blood from the right ventricle of the heart to the lungs and back to the left atrium of the heart. It transports oxygen-poor blood to the lungs, where it releases carbon dioxide (CO2) and receives oxygen (O2). Oxygenated blood then returns to the left side of the heart to be pumped into systemic circulation.

Systemic Circulation & #8211; It is the largest circulation; It supplies the blood supply to the entire body. Systemic circulation carries oxygen and other vital nutrients to cells, and captures carbon dioxide and other cell debris.
