As a subject matter expert in cardiovascular anatomy, I can tell you that the valve responsible for preventing blood from flowing back into the right ventricle of the heart is the tricuspid valve. This valve is located between the right atrium and the right ventricle and is composed of three flaps, or leaflets, which open to allow blood to flow from the right atrium into the right ventricle when the heart is in the process of receiving oxygen-poor blood from the body. When the right ventricle contracts to pump blood to the lungs for oxygenation, the tricuspid valve closes to prevent this blood from flowing back into the right atrium.

As the right ventricle contracts, the tricuspid valve closes and the pulmonary valve opens. The closure of the tricuspid valve prevents blood from backing into the right atrium and the opening of the pulmonary valve allows the blood to flow into the pulmonary artery toward the lungs.
