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

To what part of the heart is oxygenated blood returned?

A	left artium
B	ventricle
C	mitral valve
D	None of the above

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: -After oxygenation, the oxygenated blood returns to the left atrium through the pulmonary vein which then further passes on to the left ventricle. Thus the right side of the heart carries deoxygenated blood and the left side of the heart carries oxygenated blood.

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.
