Left ventricle

Detailed explanation-1: -The pulmonary artery carries oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium. The aorta carries oxygen-rich blood to the body from the left ventricle.
Detailed explanation-2: -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. The left ventricle pumps the blood to the aorta which will distribute the oxygenated blood to all parts of the body.
Detailed explanation-3: -Thus, the common pulmonary vein is incorporated into the left atrium, and four well-differentiated pulmonary veins arise, two of which drain each lung (2, 3).
