What is the work of the heart?

The heart pumps blood.

The heart is a vital organ in the human body. It has four chambers: the left atrium, the left ventricle, the right atrium and the right ventricle. The heart pumps blood, delivering oxygen and nutrients to all parts of the body. It also carries carbon dioxide and metabolites back to the lungs and out of the body. Continuous pumping of blood maintains the normal function of all tissues and organs of the body. If there is a problem with the heart, it may affect the normal circulation of blood and lead to various health problems in the body. Therefore, it is very important to keep the heart healthy and prevent heart disease.
