Question

Describe the structure of human heart with the help of a suitable diagram.

Hint:

The left ventricle pumps oxygenated blood to the entire body, while the right ventricle pumps deoxygenated blood to the lungs.

Answer 1

The human heart is a four-chambered organ, consisting of two atria and two ventricles. The right atrium receives deoxygenated blood from the body and pumps it into the right ventricle, which sends it to the lungs for oxygenation. The left atrium receives oxygenated blood from the lungs and pumps it into the left ventricle, which circulates it throughout the body. The heart also has valves that regulate blood flow between the chambers and prevent backflow.
