Explanation:
Detailed explanation-1: -Heart valves control the flow of blood so that it moves in the right direction. The valves prevent blood from flowing backward. The heart has four valves. The tricuspid valve separates the right atrium and right ventricle.
Detailed explanation-2: -Valves maintain direction of blood flow As the heart pumps blood, a series of valves open and close tightly. These valves ensure that blood flows in only one direction, preventing backflow.
Detailed explanation-3: -Why are valves important for circulation and health? Each heart valve has two functions: To open correctly so blood can empty from the chamber. To close properly so blood flows forward.
