Write a short note on double circulation of blood
Answers
Double circulation:: The blood flows twice through the heart and it is called double circulation. 1) The blood from all body parts is brought to right auricle which pumps it into right ventricle.Fron right ventricle blood is pumped to lungs (through pulmonary artery)for oxygenation
Answer:
ANSWER
The heart receives deoxygenated blood from different parts of the body, and it pumps this blood to the lungs. The oxygenated blood from the lungs returns to the heart, which is pumped again into different parts of the body by the heart. Thus, the blood passes twice through the heart making one complete round through the body. This is called double circulation.
Pulmonary and systemic circulation
The pulmonary circulation pertains to lungs. The blood flows from the right ventricle to the lungs. Pulmonary veins collect oxygenated blood from the lungs and carry it back to the heart (left auricle).
The systemic circulation pertains to the major circulation of the body. The aorta receives the blood from the left ventricle and sends it to the various parts of the body. Veins collect the deoxygenated blood from the body parts and pour it back into the right auricle
