Detailed explanation-1: -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.

Detailed explanation-2: -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-3: -Arteries are blood vessels that supply oxygen-rich blood to the entire body. They are tube-like vessels. The pulmonary artery is an exception as it carries blood poor in oxygen away from the heart instead of a vein. The pulmonary vein carries oxygen-rich blood to the heart, hence is an exception.

Detailed explanation-4: -Arteries. Blood vessels that carry oxygenated blood away from the heart to the body. Veins. Blood vessels that carry blood from the body back into the heart.
