Heart valves prevent blood from flowing backwards.

∙ 9y agoThe valves found in the heart are use to keep blood going one way and not the other (wrong) way.
The valves prevent the flow of blood from backtracking. One of each pair of valves (the entryway) is closed when the heart clenches and forces the blood from one chamber into the next chamber. Then the entryway valve opens and the chamber fills again, while the other (the forward exit) is closed, as the heart muscle relaxes between beats.
The structure of these valves is designed to prevent the flow of blood the other way, like curved, one-way doors that interlock to seal the rear of each chamber.
The valves control the flow of blood through the heart by opening and closing during the contractions of the heart. The opening and closing functions of the valves are controlled by pressure differences generated within the heart,as well as some muscles located within the heart.
The main function of the heart valves is to make sure that the 4 regions of the heart are properly seperated.
