MEDICAL PHYSIOLOGY

Detailed explanation-1: -There are four valves in the heart: aortic valve, mitral valve, tricuspid valve, and pulmonary valve. The valves are designed to control the direction of blood flow through the heart.

Detailed explanation-2: -Two of the valves, the mitral and the tricuspid valves, move blood from the upper chambers of the heart (the atria) to the lower chambers of the heart (the ventricles). The other two valves, the aortic and pulmonary valves, move blood to the lungs and the rest of the body through the ventricles.

Detailed explanation-3: -Each valve typically has three flaps, except for the mitral valve, which has two. Any of the four valves can become leaky. This means that just after the heart squeezes and pumps blood forward, some blood will leak backward through the valve. Leaking through the valve is also called valve regurgitation.

Detailed explanation-4: -Tricuspid valve. This valve is located between the right atrium and the right ventricle. Pulmonary valve. The pulmonary valve is located between the right ventricle and the pulmonary artery. Mitral valve. This valve is located between the left atrium and the left ventricle. Aortic valve.
