Why are valvers necessary in the cardiovascular system?
Valves ensure the flow of blood in a single direction. Unidirectional blood flow is very important for the circulatory system to function properly. When one of the valves do not work properly, blood does not flow properly in one direction and there is going to be some backward current. This is called shunting and can have drastic consequences if not treated immediately.
