3 lis 2023 · The valves incorporate two or three leaflets (cusps) around the atrioventricular orifices and the roots of great vessels. [Heart valves (diagram)] The cusps are pushed open to allow blood flow in one direction, and then closed to seal the orifices and prevent the backflow of blood.
To prevent blood from flowing backwards or "regurgitating" back into the heart, a system of one-way valves are present in the heart. The heart valves can be broken down into two types: atrioventricular and semilunar valves.

14 lut 2023 · The four valves of the heart prevent blood from flowing in the wrong direction, and open or close each time the heart beats. Learn more about them, here.
Four valves regulate and support the flow of blood through and out of the heart. The blood can only flow one way—like a car that must always be kept in drive. Each valve is formed by a group of folds, or cusps, that open and close as the heart contracts and dilates.
