Anatomy And Function Of Heart

The anatomy of the heart. The human heart is an organ that pumps blood throughout the body via the circulatory system supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes.

Like all muscle the heart needs a source of energy and oxygen to function.

Anatomy and function of heart. The heart is a muscular organ about the size of a closed fist that functions as the bodys circulatory pump. They form a figure 8 pattern around the atria and around the bases of the great vessels. The wall of the heart consists of three layers of tissue.

Epicardium protective layer mostly made of connective tissue. There are four chambers in the heart that together function as a two sided pump. It is divided by a partition or septum into two halves and the halves are in turn divided into four chambers.

It is the contraction of the myocardium that pumps blood through the heart and into the major arteries. Myocardium the muscles of the heart. The left side of the heart pumps blood out into the body through the arteries while the right side of the heart collects blood through the veins.

The hearts pumping action is regulated by an electrical conduction system that coordinates the contraction of the various chambers of the heart. Basic anatomy of the heart. In the simplest terms the heart is a pump made up of muscle tissue.

The muscle pattern is elegant and complex as the muscle cells swirl and spiral around the chambers of the heart. It takes in deoxygenated blood through the veins and delivers it to the lungs for oxygenation before pumping it into the various arteries which provide oxygen and nutrients to body tissues by transporting the blood throughout the body. Endocardium lines the inside of the heart and protects the valves and chambers.

This amazing muscle produces electrical impulses that cause the heart to contract. The heart is situated within the chest cavity and surrounded by a fluid filled sac called the pericardium.
