PATHOLOGY

Detailed explanation-1: -Pulmonary arteries carry the blood to your lungs, where it receives oxygen. Pulmonary veins move the blood oxygen-rich blood to the left side of your heart. The aorta (the main artery in your body) carries the blood from the left side of your heart to the rest of your body through many branches of arteries.

Detailed explanation-2: -The aorta is a big artery that leaves the heart carrying this oxygenated blood. Branches off of the aorta send blood to the muscles of the heart itself, as well as all other parts of the body. Like a tree, the branches gets smaller and smaller as they get farther from the aorta.

Detailed explanation-3: -Arteries: Carry oxygen-rich blood away from the heart. Veins: Carry deoxygenated blood from organs back to the heart.
