The human heart has four separate chambers: two atria and two ventricles. Specialized muscles in the walls of these chambers pump blood throughout the body with each beat of the heart.
The two atria contract to pump blood into the ventricles. The two ventricles then contract to pump the blood out of the heart and into the arteries where it begins its journey throughout the body.
The blood passes from one chamber to another and moves from the heart to the arteries by passing through specialized valves. The valves ensure each contraction directs the blood to the correct location. One of these valves is the aortic valve.
The aortic valve facilitates the passage between the aorta and the left ventricle. With each contraction of the left ventricle, the three flaps of the aortic valve open allowing blood to flow through. The flaps then close as the muscles relax after the … Read More
