Answer 1

Answer:-

Double circulation:

A type of circulation in which blood flows through the heart twice is called double circulation. This type of circulatory system has separate systemic circulation and pulmonary circulation.

Systematic circulation:

• The flow of oxygenated blood from the left ventricle of the heart to various parts of the body and deoxygenated blood from various parts of the body to the right atrium is called systemic circulation.
• The systemic arteries arising from aorta carry oxygenated blood from the left of the ventricle to various parts of the body.
• The systemic veins carry deoxygenated blood from various parts of the body to the right atrium of the heart.

Pulmonary circulation:

• The flow of deoxygenated blood from the right ventricle to the lungs and the return of oxygenated blood from the lungs to the left atrium is called pulmonary circulation.
• The oxygenated blood from the lungs returns to the left atrium of the heart through two pulmonary veins, one from each lung.
