The valves in the body makes sure that the fluids flow in one direction, and prevent backflow. In the heart the valves prevent the backflow of blood to make sure it travels in one direction (atrium to ventricle). The valves are also present in the lymphatic system that makes the lymph travel in one direction.

when heart valves open and close, they cause suction and pressure. each time you hear those thump, thump, thump sounds, those are your valves closing and openning.
