What are the functions of the tricuspid, bicuspid and semilunar valves?
Original Khojo Papers practice question — not from a past board paper.
Answer
The tricuspid valve between the right atrium and right ventricle and the bicuspid valve between the left atrium and left ventricle prevent the backflow of blood into the atria when the ventricles contract. The semilunar valves at the mouths of the pulmonary artery and the aorta prevent blood returning to the ventricles when they relax.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The closing of these valves produces the two heart sounds.
