Detailed explanation-1: -The arteries (red) carry oxygen and nutrients away from your heart, to your body’s tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body’s tissues.
Detailed explanation-2: -Your main pulmonary artery and your aorta are the two great vessels that carry blood out of your heart. A crucial difference is that your pulmonary artery carries oxygen-poor (deoxygenated) blood, while your aorta carries oxygen-rich (oxygenated) blood.
Detailed explanation-3: -Your body contains about 60, 000 miles of blood vessels. There are three types of blood vessels: Arteries carry blood away from your heart. Veins carry blood back toward your heart.
