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: -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. Capillaries have thin walls that allow oxygen, nutrients, carbon dioxide and waste products to pass through, to and from the tissue cells.

Detailed explanation-3: -Pulmonary vein is the only vein that carries oxygenated blood as they carry blood from lungs to the heart and, pulmonary artery is the only artery that carry deoxygenated blood.
