Heart valves control the flow of blood into, out of, and within the chambers of the heart. The main function is to let blood flow in one direction only, ensuring that blood does not flow backwards.

valves in the heart are like doors.

there are 4 main chambers of the heart; the left and right atrium & the left and right ventricle.

the valves are what help the blood pass from and into each chamber of the heart. there are valves between each atrium and ventricle.

valves also help the blood from moving backward. it keeps the blood moving in a forward direction.

The functions of valves in the heart is to pump the oxygen-rich blood to the rest of the body. This blood would have just returned from the lungs. Without the valves, the blood would pool at your feet and your brain and other vital organs would not be able to receive blood.

there is the bicuspid valve which opens up to allow oxygenated blood into the heart after the oxygenated blood has entered the heart, i closes to prevent flowback of the blood, then the semi lunar valve opens up which allows the deoxygenated blooto exit, and once it has exited, it closes for the same reason which is to prevent flowback. so basically it is to prevent the flowback of blood
