Write the process of circulation of blood in the atria and ventricles of human heart. (120 words maximum)
Answers
Answer:
The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.
Double circulation is the process through which blood is circulated in the atria and ventricles of heart .
EXPLANATION:
1.from the upper body and lower body deoxygenated blood is carried by superior and inferior vena cava to right atria.
2. from right atria it is passed to right ventricles through tricuspid valves
3. from ventricle it is passed to pulmonary artery through semilunar valves from which it passed to lungs
4.In lungs it gets pure and convert to oxygenated blood and passed to left atria through pulmonary vein.
5.from atria it passed to left ventricle through bicuspid valve and finally to aorta through semilunar valve
6.from aorta it is transported to all body organs
