Final answer:
The valve between the right atrium and the right ventricle is the tricuspid valve, which is an atrioventricular valve situated on the right side of the heart.
Step-by-step explanation:
The valve between the right atrium and right ventricle is the tricuspid valve. This is an atrioventricular valve, one of two in the heart, located between the atria and the ventricles. The tricuspid valve is on the right side of the heart and allows blood to flow from the right atrium into the right ventricle.
In contrast, the bicuspid valve, also known as the mitral valve, is located on the left side of the heart and controls blood flow from the left atrium to the left ventricle. The pulmonic valve is also known as the pulmonary semilunar valve and is responsible for controlling blood flow from the right ventricle into the pulmonary artery, which leads to the lungs.
The aortic valve is another semilunar valve that controls blood flow from the left ventricle into the aorta, distributing oxygen-rich blood to the body.
