In this lectures we will discusses about Heart || Valves || Chambers || Cardiovascular system|| Hindi
The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system. The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs.
The heart consists of four chambers in which blood flows. Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle. The left ventricle pumps the blood to the aorta which will distribute the oxygenated blood to all parts of the body.

Pulmonary Valve (or Pulmonic Valve)
Mitral Valve. Has two leaflets.
Aortic Valve. Has three leaflets, unless it's abnormal from birth, i.e., bicuspid aortic valve.
