Answer 2

Arteries are blood vessels that carry oxygenated blood away from the heart. arteries are more muscular than veins and they carry blood away from the heart.

Capillaries are the smallest of a body's blood vessels and are part of the microcirculation. They are only 1 cell thick. These microvessels, connect arterioles and venules, and enable the exchange of water, oxygen, carbon dioxide, and many other nutrient and waste chemical substances between blood and surrounding tissues.

Veins are blood vessels that carry blood towards the heart. Most veins carry deoxygenated blood from the tissues back to the lungs; exceptions are the pulmonary and umbilical veins, both of which carry oxygenated blood.
