Main function of the heart

The main function of the heart is to pump the blood into the lungs so that it is saturated with oxygen and then pump it into the body to supply the cells with oxygen. The heart, along with the blood vessels, forms the cardiovascular system.




take blood from vena-cava (both higher and worse)
pumping through the pulmonary artery into the lungs
after the lungs oxygenate the received blood, blood is directed to the heart through the pulmonary vein
the heart then pumps the oxygenated blood for the whole body through the aorta
Now, if you want to understand each point in detail, here’s:

 

Deoxygenated blood is received by the heart from the body through a better and inferior main vein. The highest vena-cava carries deoxygenated blood from the upper region and the inferior main vein (which is larger than the higher one) from the lower part of the body.

 

Blood from the main cava vein is picked up by the right atria. The right vestibule also receives blood from the coronary sinus (vessels of the heart itself). This blood (deoxygenated) flows into the right ventricle. The hole between right auric and ventilated is guarded by a double-sided gate valve called mitral valve. Now the blood from the right ventricle is pumped to the lungs (for oxygenation) through the pulmonary artery.

 

After oxygenation of the blood in the lungs, it is again taken up by the heart … in the left atrium through the pulmonary vein. Now the blood from the left atrium flows into the left ventricle. The opening of the left atrium and the ventricle is guarded by a tricuspid valve.
The left ventricle now contains oxygenated blood pumped through the aorta and reaches all organs through the arteries.




structure and function

The structure and function of the heart, arteries, veins, and capillaries are essential for the functioning of the cardiovascular system. The general function of the circulatory system is to transport blood and lymph around the body. In this way, it provides the body with oxygen and nutrients, removes waste from the body, takes part in the regulation of body temperature and helps fight infections. In the cardiovascular system, which is the primary purpose of Pre-PDHPE, the structure and function of the heart, arteries, veins, and capillaries help to achieve this greater goal of the cardiovascular system.
