Function of Heart
The heart performs the following important functions:
The primary function of the heart is to pump blood throughout the body.
It supplies oxygen and nutrients to the tissues and removes carbon dioxide and wastes from the blood.
It also helps to maintain adequate blood pressure throughout the body.
The heart functions in the following ways:
The arteries receive oxygenated blood from the heart and supply it throughout the body. Whereas, the veins carry the deoxygenated blood form all the body parts to the heart for oxygenation.
The right atrium receives blood from the veins and pumps it to the right ventricle.
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.
Improper functioning of the heart results in heart diseases such as angina pectoris, congestive heart failure, cardiomyopathy, cardiac arrest, etc.
