why does heart pump blood
Asked by dipika.sahu1 | 24 Jan, 2024, 19:27: PM
The heart receives deoxygenated blood from different parts of the body, and it pumps this blood to the lungs. Pumping blood through the lungs removes carbon dioxide and refreshes the blood with oxygen. The oxygenated blood from the lungs returns to the heart, which it pumps again into different parts of the body.
