The structure that lies between the right atrium and right ventricle is the what?

Explanation:
The structure between the right atrium and the right ventricle is the tricuspid valve, the right atrioventricular valve. It opens to let blood move from the right atrium into the right ventricle when the atrium fills, and it closes during ventricular contraction to prevent backflow into the atrium. The mitral valve sits between the left atrium and left ventricle, the pulmonary valve is the outflow valve from the right ventricle to the pulmonary artery, and the aortic valve is the outflow valve from the left ventricle to the aorta.
