The Heart and its Functions

The human heart is a finely-tuned instrument that serves the whole body. It is a muscular organ around the size of a closed fist, and it sits in the chest, slightly to the left of center.

The function of the heart in any organism is to maintain a constant flow of blood throughout the body. This replenishes oxygen and circulates nutrients among the cells and tissues.

Following are the main functions of the heart:

• One of the primary functions of the human heart is to pump blood throughout the body.
• Blood delivers oxygen, hormones, glucose and other components to various parts of the body, including the human heart.
