Question

The valves which allow blood to flow from the ventricles into the arteries and not in the opposite direction are

• A. Bicuspid and tricuspid valves
• B. AV valve (atrio ventricular valve) and semilunar valve
• C. Aortic valve and mitral valve
• D. Semilunar valve

Answer 1

The correct option is D Semilunar valve

Valves are the membranous structure which prevents the backflow of the blood. The semilunar valves are present at the point at which the pulmonary artery and the aorta leave the ventricles. The pulmonary valve guards the orifice between the right ventricle and the pulmonary artery. The aortic valve protects the orifice between the left ventricle and the aorta.

So, the correct answer is option D.
