PATHOLOGY

Detailed explanation-1: -A crucial difference is that your pulmonary artery carries oxygen-poor (deoxygenated) blood, while your aorta carries oxygen-rich (oxygenated) blood. In fact, your pulmonary arteries are the only arteries in your body that carry oxygen-poor blood.

Detailed explanation-2: -Arteries carry blood away from the heart and veins carry blood to the heart.

Detailed explanation-3: -The aorta carries oxygenated blood from the left ventricle (one of your heart’s four chambers) to the rest of your body. The ascending aorta is the first part closest to your heart. This portion has two small branches. These are the major coronary arteries that supply oxygen-rich blood to the heart muscle.

Detailed explanation-4: -Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide. These roadways travel in one direction only, to keep things going where they should.
