Question

What is function of heart

Answer

• Take the blood from vena-cava(both superior and inferior)

• Pump it through the pulmonary artery to the lungs

• After the lungs oxygenate the received blood, blood is sent 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 every point in detail, here we go:

• Deoxygenated blood is received by the heart from the body through superior and inferior vena cava.

• The superior vana-cava carries deoxygenated blood from the upper region and inferior vena-cava(which is larger than the superior one) from the lower region of the body.

• The blood from both the vena-cava is received by the right atrium. Right atrium also receives blood from coronary sinuses(vessels of the heart itself).

• This blood (deoxygenated) flows into the right ventrical.

• The opening between the right aurical and ventrical is guarded by a tricuspid valve.

• Now blood from right ventricle is pumped into the lungs(for oxygenation) through the pulmonary artery.

• After the blood is oxygenated in the lungs, it is again received by the heart…in the left atrium through the pulmonary vein.

• Now the blood from left atrium flows into the left ventricle.

• The opening of the left atrium and ventricle is guarded by the bicuspid valve.

• The left ventricle is now containing the oxygenated blood which is pumped through the aorta and reaches all the organs through arteries.
