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

The chamber of the heart that receives oxygenated blood as it returns from the lungs is the ____

A	Left Atrium
B	Left Ventricle
C	Right Atrium
D	Right Ventricle

Explanation:

Detailed explanation-1: -Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins. Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber.

Detailed explanation-2: -The blood that is returned to the right atrium is deoxygenated, then passed into the right ventricle to be pumped through the pulmonary artery to the lungs for reoxygenation and removal of carbon dioxide. The left atrium receives newly-oxygenated blood from the lungs through the pulmonary veins.

Detailed explanation-3: -Left atrium: one of the four chambers of the heart. The left atrium receives blood full of oxygen from the lungs and then empties the blood into the left ventricle.

Detailed explanation-4: -A typical heart has two upper and two lower chambers. The upper chambers, the right and left atria, receive incoming blood. The lower chambers, the more muscular right and left ventricles, pump blood out of the heart.
