Answer:

Question:-

Functioning of the heart.

Introduction:-

The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system.Blood provides the body with oxygen and nutrients, as well as assisting in the removal of metabolic wastes. In humans, the heart is located between the lungs, in the middle compartment of the chest.

Function:-

The heart has four chambers:

The right atrium receives blood from the veins and pumps it to the right ventricle.The right ventricle receives blood from the right atrium and pumps it to the lungs, where it is loaded with oxygen.The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle.The left ventricle (the strongest chamber) pumps oxygen-rich blood to the rest of the body. The left ventricle’s vigorous contractions create our blood pressure.

The coronary arteries run along the surface of the heart and provide oxygen-rich blood to the heart muscle. A web of nerve tissue also runs through the heart, conducting the complex signals that govern contraction and relaxation. Surrounding the heart is a sac called the pericardium.
