Question

Quizplus · Accepted Answer

The valve between the right atrium and right ventricle is called the right atrioventricular (RV) or tricuspid valve. It prevents backflow of blood from the ventricle to the atrium when the ventricle contracts. The pulmonary valve is located between the right ventricle and pulmonary artery, allowing blood to flow from the right ventricle to the lungs for oxygenation. The bicuspid valve is located between the left atrium and left ventricle, while the aortic valve is located between the left ventricle and aorta.
