The labeled structure that prevents blood flow from the right ventricle back into the right atrium is the tricuspid valve, which is labeled as B in the diagram. The tricuspid valve is a one-way valve that opens to allow blood to flow from the right atrium to the right ventricle during diastole and then closes during systole to prevent backflow of blood into the right atrium.
