When blood leaves this chamber of the heart, it heads out to the body (not the lungs)
A
left atrium
B
right atrium
C
left ventricle
D
right ventricle
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: -The aorta is the body’s largest artery. It carries oxygen-rich blood from the left ventricle to the rest of the body. Beneath the tough fibrous coating of the heart, you can see it beating. Inside the chambers are a series of one-way valves.

Detailed explanation-3: -When the ventricle is full, the tricuspid valve shuts. This prevents blood from flowing backward into the right atrium while the ventricle contracts. As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs, where it is oxygenated.

Detailed explanation-4: -The right atrium receives blood from the body. This blood is low in oxygen. This is the blood from the veins. The right ventricle pumps the blood from the right atrium into the lungs to pick up oxygen and remove carbon dioxide.

Detailed explanation-5: -The arteries (red) carry oxygen and nutrients away from your heart, to your body’s tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body’s tissues.
