The valves that connect the heart chambers, including the atrioventricular valves (mitral and tricuspid) and the semilunar valves (pulmonary and aortic), function to ensure unidirectional blood flow through the heart. They open and close in response to pressure changes during the cardiac cycle, preventing backflow of blood as it moves from the atria to the ventricles and from the ventricles to the arteries. This coordinated action is crucial for maintaining efficient circulation and optimal heart function.
Valves prevent the backflow of blood.
Valves are present in heart are used to prevent backflow of blood in heart due to reduce in pressure in atrium.
Circulatory system are connected by a network of arteries, veins and capillaries. They connect the body with heart. Inside the heart, various valves connect different chambers.
They are similar in size, anatomy, and function. They both have four chambers and four valves, which is why it is sometimes used for a heart transplant
The word that describes the thin membrane lining the chambers of the heart and the heart valves is "endocardium." This innermost layer of the heart is composed of endothelial cells and connective tissue, providing a smooth surface for blood flow and playing a crucial role in heart function.
4 valves
The lower chambers of the heart have a different function than the upper chambers. The lower chambers pump the blood out of the heart into the body and lungs.

To view the heart's chambers and valves.
It has a similar shape, structure, chambers and valves.
Four hollow chambers surrounded by muscle. Two of the chambers have inlet and outlet valves.
