Watch a watermelon wrapped in rubber bands explode in slow-motion. (CBS News) Have you ever wondered if you could cause a watermelon to explode by wrapping a ton of rubber bands around it?

Four valves control the flow of blood from the atria to the ventricles and from the ventricles into the two large arteries connected to the heart. 1  The tricuspid (tri-CUSS-pid) valve is in the right side of the heart, between the right atrium and the right ventricle.
Blood moves through the four chambers as the heart pumps. There are four valves which control the flow of blood through the heart. They are called the aortic valve, the mitral valve, the pulmonary valve, and the tricuspid valve. With each beat, the valves open and close to keep blood moving in the right direction.
