an orifice that blood passes through in systole, and it is also an occluding (blocking) mechanism necessary to prevent the flow of blood during diastole
a structure within the heart that prevents the backflow of blood by opening and closing with each heartbeat
The structure at each exit of the four chambers of the heart that allows blood to exit but not to flow back in.
One of the four structures in the heart that control the flow of blood by opening and closing with each heartbeat. The valves permit the flow of blood in only one direction.
one of the four structures in the heart that control the flow of blood to and from the heart.
A structure in the heart that opens and closes with each heartbeat. The heart has four valves that work together to control the flow of blood through the heart and body.
Heart valves are four sets of flaps that control the direction that blood pumps around the heart.
In anatomy, the heart valves are valves in the heart that maintain the unidirectional flow of blood by opening and closing depending on the difference in pressure on each side. The mechanical equivalent of the heart valves would be the reed valves.
