Introduction The heart is a complex organ that pumps blood throughout the body. It consists of four chambers and four valves that work together to ensure that blood flows in the right direction. The chambers are the atria and the ventricles, and the valves are the tricuspid, the mitral, the pulmonary, and the aortic. In this article, we will explain the basic structure and function of each chamber and valve, and how they affect your health. Overview of Heart Valve Anatomy The heart has four valves that control the flow of blood through the chambers. The valves are made of thin flaps of tissue called leaflets or cusps. The leaflets open and close to allow blood to move in one direction and prevent it from flowing backward. The four valves are: The tricuspid valve is located between the right atrium and the right ventricle. The pulmonary valve is located between
