Arteries (red) carry oxygen and nutrients away from your heart, to the tissues of your body. Veins (blue) bring oxygen-poor blood back to the heart. Arteries start in the aorta, the large arteries leave the heart. They carry oxygen-rich blood from the heart to all tissues in the body.

Do arteries carry blood?

upper body circulation

Arteries throughout the body (red) Delivers oxygenated blood and nutrients To all tissues in the body, veins (blue) return oxygen-poor blood to the heart. The aorta is the large artery that leaves the heart.

Does blood flow to arteries or veins first?

blood vessels: circulating blood

Through the thin walls of capillaries, oxygen and nutrients enter the tissue from the blood, and waste products enter the blood from the tissue.blood from capillaries into venules and then into vein Back to the heart.

How does blood flow from arteries to veins?

capillary Connect arteries to veins. Arteries carry oxygen-rich blood to capillaries where the actual exchange of oxygen and carbon dioxide occurs. Capillaries then carry the waste-rich blood into veins for delivery back to the lungs and heart.

What is the thinnest artery called?

capillary It is the smallest and thinnest blood vessel in the body. They receive blood from arterioles and form networks called capillary beds, where gases, nutrients, and other substances exchange waste with tissues.

Which artery is the largest in the human body?
