The ________ Valve Prevents Backflow of Blood from the Aorta

Question

The ________ valve prevents backflow of blood from the aorta into the ________ ventricle.
A)pulmonary; left
B)aortic; left
C)aortic; right
D)pulmonary; right

Accepted Answer

The aortic valve is located between the left ventricle and the aorta, and its main function is to prevent the backflow of blood from the aorta into the left ventricle. The pulmonary valve, on the other hand, is located between the right ventricle and the pulmonary artery. Therefore, options A and D are incorrect. The aortic valve is not located between the right ventricle and the aorta, so option C is also incorrect.
