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: -Arteries always carry blood away from the heart. Usually the blood is oxygenated; the exceptions are the pulmonary arteries, which carry blood away from the heart to the lungs to become oxygenated.
Detailed explanation-3: -Generally, veins carry deoxygenated blood from the body to the heart, where it can be sent to the lungs. The exception is the network of pulmonary veins, which take oxygenated blood from the lungs to the heart.
Detailed explanation-4: -Capillaries transport blood between arteries and veins. Arteries are the largest blood vessels with the thickest walls, and capillaries are the smallest. Arteries are only located deep inside your muscles, but capillaries are inside tissues all over your body.
