Verified step by step guidance1
Step 1: Begin by identifying the anatomical structure in question, which is the right atrioventricular valve. This valve is also known as the tricuspid valve.
Step 2: Recall the function of the tricuspid valve. It is located between the right atrium and the right ventricle, and its primary role is to prevent backflow of blood during ventricular contraction.
Step 3: Understand the term 'cusps.' Cusps are the flaps or leaflets of the valve that open and close to regulate blood flow. Each valve in the heart has a specific number of cusps.
Step 4: Note that the prefix 'tri-' in 'tricuspid' indicates the number of cusps. 'Tri-' means three, which is a key clue to the answer.
Step 5: Based on the anatomical name and function, conclude that the right atrioventricular valve (tricuspid valve) has three cusps.
