Blood leaving the left ventricle passes through what structure next?
A
right ventricle
B
pulmonary vein
C
semilunar valve
D
aorta
Explanation: 

Detailed explanation-1: -The left ventricle (LV) pumps the oxygen-rich blood through the aortic valve (AoV) into the aorta (Ao), the main artery that takes oxygen-rich blood out to the rest of the body.

Detailed explanation-2: -Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle.

Detailed explanation-3: -The blood first enters the right atrium from the superior and inferior vena cava. The blood then flows through the tricuspid valve into the right ventricle. The blood then moves through the pulmonary valve into the pulmonary artery. The pulmonary artery carries blood to the lungs where it takes up oxygen.
