Detailed explanation-1: -The aorta carries oxygen-rich blood to the body from the left ventricle.

Detailed explanation-2: -Arteries carry blood from the heart to different organs and hence it is oxygen rich in most cases. But, the blood from the heart to the lungs is carried by the pulmonary artery which needs oxygen.

Detailed explanation-3: -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-4: -Arteries carry blood away from the heart and veins carry blood back to the heart.
