Describe double circulation of blood in human beings. Why is it necessary?
Solution:
Double circulation means, in a single cycle blood goes twice in the heart. The process helps in separating
oxygenated and deoxygenated blood to maintain a constant body temperature.
The double circulatory system of blood includes
- Pulmonary circulation
- Systemic circulation.
Pulmonary circulation:
The right ventricle pumps deoxygenated blood into the lungs where it is oxygenated. The oxygenated
blood is brought back to the left atrium, from there it is pumped into the left ventricle and finally blood
goes into the aorta for systemic circulation.
Systemic circulation:
The oxygenated blood is pumped to various parts of the body from the left ventricle. The deoxygenated
blood from different parts of the body passes through vena cava to reach right atrium. The right atrium
transfers the blood into right ventricle.
