The human heart has four valves, aortic, mitral, pulmonary and tricuspid that control blood flow. As they open and close, they make the noise known as a heartbeat.
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.
The four valves in order of circulation are: Tricuspid Valve. Has three leaflets or cusps. Separates the top right chamber (right atrium) from the bottom right chamber (right ventricle). Opens to allow blood to flow from the right atrium to the right ventricle.
A heart valve is a biological one-way valve that allows blood to flow in one direction through the chambers of the heart. A mammalian heart usually has four valves. Together, the valves determine the direction of blood flow through the heart.
The heart valves are uniquely designed gates that promote the unidirectional flow of blood through the heart. They are attached to special muscular appendages that help to keep them stable. This article aims to explore the embryology and gross anatomy of the heart valves.
Visit heart valves and circulation to get a better understanding of the basics of blood flow. Understanding the role of each of the four heart valves can help you learn why you might need to watch for certain signs and symptoms.
Each heart valve has two functions: To open correctly so blood can empty from the chamber; To close properly so blood flows forward; When the valves and chambers fail to move blood properly, symptoms eventually may develop and require critically important treatment.
