Three-cusped fibrous valve at entrance from left ventricle into aorta. Prevents regurgitation of blood back into ventricle.

a semilunar valve between the left ventricle and the aorta; prevents blood from flowing from the aorta back into the heart

Flap-like structure connecting left ventricle of the heart to the aorta.

tricuspid (3 leaves) valve between the heart and aorta. In Marfan Syndrome, this valve can be bicuspid (have only 3 leaves). Back to the top

Controls blood flow from the left ventricle into the aorta.

Four valves are in the heart with two on the left side and two on the right side. On each side there is an inflow valve to the ventricle - the main pumping chamber - and an outflow valve. The aortic valve is the outflow valve for the left ventricle, and as such opens when the ventricle squeezes blood out and then closes to keep blood from leaking back into the ventricle.

A three leaflet valve which naturally occurs at the junction between the left ventricle and the aorta. The aortic valve protects the left ventricle from being swamped with blood coming backwards after ejection from the heart.

One of the four valves in the heart, this valve is situated at exit of the left ventricle of the heart where the aorta (the largest of all arteries) begins. See the entire definition of Aortic valve

the valve that regulates blood flow from the heart into the aorta.

The valve between the left side of the heart (left ventricle) and the large blood vessel (aorta) going to the body.

The aortic valve is the last valve through which the blood passes before it enters the aorta or main blood vessel of the body. The valve prevents blood from leaking back into the left ventricle from the aorta after it has been ejected from the heart

the valve between the aorta and the left ventricle (main pumping chamber). The aortic valve usually has three leaflets.

The heart valve between the left ventricle and the aorta. See larger view

The one-way valve between the left ventricle and the aorta.

valve that regulates the flow of blood from the heart into the aorta

This valve controls blood flow from the heart through to the aorta.

a cardiac membrane that controls the flow of blood out of the heart and into the aorta.

The heart valve between the aorta and the left ventricle.

The valve that sits at the junction of the left ventricle and the aorta. When the valve is open it allows blood to flow from the left ventricle to the aorta and when closed, prevents any backward flow.

the semilunar valve between the left ventricle and the aorta. It prevents blood from flowing back into the ventricle. It consists of three flaps, or cusps.

The valve, normally having three cusps (flaps), lying between the left ventricle and the aorta. It allows the flow of blood into the major artery taking blood away from the heart.

valve between the left ventricle and the ascending aorta.

The three cusp, semilunar valve located between the left ventricle and the aorta that prevents the flow of blood back into the left ventricle.

The valve that controls the flow of blood between the aorta and the left ventricle, the heart's major pumping chamber.

Heart valve which separates the left ventricle from the aorta.

One of two valves that control bloodflow out of the heart. The aortic valve is located between the left ventricle and the aorta, the largest artery in the human body. Once blood leaves the heart through this valve to flow into the aorta, the valve closes to prevent blood from flowing back into the heart. See also pulmonary valve . More about How your heart works.

is a heart valve that regulates blood flow between the left ventricle and the aorta.

One of the valves in the heart which opens and closes when the heart beats. The aortic valve is between the left ventricle and the aorta. The cusps of the aortic valve close each time the heart beats. This prevents blood from flowing back into the left ventricle after it has gone into the aorta.

The heart valve that regulates blood flow from the left ventricle and the aorta. It has three flaps or cusps.

Are semilunar valve that separate the left ventricle from the aorta. They open in systole (ventricular contraction) to allow flow of blood out of the aorta and close at the end of ventricular contraction to prevent backflow of blood into the left ventricle.

Valve located where the aorta meets the left ventricle of the heart. It allows the blood to flow from the heart into the aorta and prevents back flow.

The aortic valve is one of the valves of the heart. It lies between the left ventricle and the aorta.
