Question

describe double circulation in human heart

Answer 1

in double circulation of heart blood passes through the heart in a single cycle.
blood coming from lungs through pulmonary vein carrying pure blood enter  our left atrium from there it enters left ventricle and from there through arota is circulated to organs .
then by venacava it enter right atrium and then right ventricle from there it goes to lungs by pulmonary artery.
double circulation is important to maintain the body temperature of our body and seperate oxygenated and deoxygenated blood

Answer 2

During double circulation, the blood flows twice

through the heart. The circulation of blood from

the right ventricle to the lungs, and from the

lungs to the left auricle is called pulmonary

circulation. The circulation of blood from the

left ventricle to the body parts and from the

body parts to the right auricle is called system

circulation.

Double circulation of blood is necessary for

constant and efficient supply of oxygen to the

body which is needed for high energy needs of

our body and to maintain the body temperature.
