ANATOMY

Detailed explanation-1: -Overview. There are four valves in the heart: aortic valve, mitral valve, tricuspid valve, and pulmonary valve.

Detailed explanation-2: -A normal heart and heart valve problems The four heart valves, which keep blood flowing in the right direction, are the mitral, tricuspid, pulmonary and aortic valves. Each valve has flaps (leaflets) that open and close once per heartbeat.

Detailed explanation-3: -There are four valves associated with the heart. The two atrioventricular valves, and the two semilunar valves. the two semilunar valves, the aortic and pulmonary, have a similar design, each consisting of a fibrous valve ring at the base of the vessel, with three leaflets, each occupying a third of closed valve.

Detailed explanation-4: -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-5: -Tricuspid valve. Located between the right atrium and the right ventricle. Pulmonary valve. Located between the right ventricle and the pulmonary artery. Mitral valve. Located between the left atrium and the left ventricle. Aortic valve.
