Question

Describe the circulation procedure of heart.plzz

Answer 1

The circulatory system of the lungs is the portion of the cardiovascular system in which oxygen-depleted blood is pumped away from the heart, via the pulmonary artery, to the lungs and returned, oxygenated, to theheart via the pulmonary vein. ... The pulmonary vein returns the now oxygen-rich blood to the left atrium.

Answer 2

1.Firstly,oxygenated blood are coming from the lungs to the left artrium through the pulmonary veins.

2.Second, heart pumps blood periodically ,then oygenated blood pumps to the left ventrical through the vaive 1.

3.Then these blood is caried by main arota through the valve4 through the body.

4. These oxygeneted blood is used up by body cellsand produce waste product calle CO2 .

5.Then deoxygeneted or impure blood is caried out by vena cava to right artrium .

6.These deoxygeneted blood is then pumped to the right ventrical throygh the valve 2.

7.These impure blood is then caried out by pulmonary artries through the vaive3 to bach to the lungs for purification.

This lke these process is cont. through the body.It should br noted that in human beinfs there is a double circulation and in othet animals like frogs,ratsand lizards there is only one circulation.In one circulation all oxygeneted is transfered all out the body.But in human beings it need double circultion.
