Aortic - Valve

As the heart relaxes, pressure in the ventricle drops below that of the aorta. The back-pressure of the blood in the aorta pushes the leaflets together to form a tight seal, creating the second heart sound (the "dub" in "lub-dub"). Common Conditions and Diseases

The aortic valve is located at the aortic root , where the left ventricle connects to the ascending aorta. aortic valve

In a healthy heart, the valve typically consists of three thin, half-moon-shaped flaps called leaflets or cusps . As the heart relaxes, pressure in the ventricle

The aortic valve is one of the four main valves in the human heart, serving as the final "gatekeeper" that regulates blood flow from the left ventricle into the aorta . Its primary function is to ensure that oxygen-rich blood moves in a single direction—out to the rest of the body—while preventing any backflow into the heart. Anatomy and Structure In a healthy heart, the valve typically consists

Each leaflet is composed of three distinct layers: the fibrosa (aortic side, primarily collagen), the spongiosa (middle layer, shock-absorbing), and the ventricularis (ventricular side, rich in elastin).
