During the normal cardiac cycle, the bicuspid valve opens when: the pressure in the right ventricle is greater than in the right atrium b. the pressure in the right atrium is greater than in the right ventricle c. the pressure in the left atrium is greater than in the left ventricle d. the pressure in the left ventricle is greater than in the left atrium e. the pressure in the right ventricle is greater than in the pulmonary artery

Sagot :

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.
