explain the working of human heart in detail for class 10th
Answers
The human heart is about the size of a human fist and is divided into four chambers, namely two ventricles and two atria. The ventricles are the chambers that pump blood and atrium are the chambers that receive blood. ... Then, the oxygenated blood is received by the left atrium from the lungs via the pulmonary veins.
The primary function of the heart is to pump blood throughout the body. The right ventricle pumps the blood received from the right atrium to the lungs. The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle. The left ventricle pumps the oxygenated blood throughout the body.
