Structure and Function of the Heart
The heart is a vital organ in the human body that pumps blood throughout the circulatory system. It is located in the chest, slightly to the left of the midline, and is protected by the rib cage.
Anatomy of the Heart
The heart is comprised of four chambers: two atria and two ventricles. The right atrium receives deoxygenated blood from the body and pumps it into the right ventricle, which then sends the blood to the lungs for oxygenation. The oxygenated blood returns to the left atrium, which then pumps it into the left ventricle. The left ventricle is responsible for pumping the oxygenated blood out to the rest of the body.
Function of the Heart
The main function of the heart is to pump blood throughout the body, delivering oxygen and nutrients to the cells and removing waste products. This is accomplished through a coordinated series of contractions and relaxations, known as the cardiac cycle.
