Answer:
b. the pressure in the right atrium is greater than in the right ventricle
Explanation:
A bicuspid valve is an aortic valve that only has two leaflets, instead of three. The function of aortic valve is to regulates blood flow from the heart into the aorta. The valve opens and closes because of pressure differences. The opening of the valve occurs when the pressure is greater in the left atrium than ventricle whereas, closing happens when there is greater pressure in the left ventricle than atrium so we can conclude that the pressure in the right atrium is greater than in the right ventricle.
