The heart features four types of valves which regulate the flow of blood through the heart. These valves permit blood flow only in one direction, and prevent back flow of blood. The four types of valves are:
- Tricuspid Valve: This valve separates the right atrium from the right ventricle, and regulates the blood flow between them. Tricuspid valves allow blood to flow from the right atrium into the right ventricle, and prevent back flow of the same.
- Pulmonary Valve: This valve separates the right ventricle from the left pulmonary artery. These valves prevent the control the flow of blood from the right ventricle into the left pulmonary artery.
- Mitral Valve: Bicuspid valve or Mitral valve separates the left ventricle from the left atrium.
- Aortic Valve: This valve separates the left ventricle from the aorta, and controls the blood flow from the ventricle into the rest of the body.
