Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Which valve closes off the lower left chamber that holds the oxygen-rich blood before it is pumped out to the body?

A	Tricuspid Valve
B	Aortic Valve
C	Bicuspid Valve
D	None of the above

Explanation:

Detailed explanation-1: -When the left ventricle contracts, the mitral valve closes and the aortic valve opens. This is so blood flows into the aorta and out to the rest of the body. While the left ventricle is relaxing, the right ventricle also relaxes. This causes the pulmonary valve to close and the tricuspid valve to open.

Detailed explanation-2: -The left ventricle pumps the blood from the left atrium out to the body, supplying all organs with oxygen-rich blood.

Detailed explanation-3: -mitral valve: located between the left atrium and the left ventricle. aortic valve: located between the left ventricle and the aorta.

Detailed explanation-4: -The mitral valve separates the left atrium and left ventricle. The pulmonary valve separates the right ventricle and the pulmonary artery.
