Question

difference between arteries and veins​

Answer 1

Step-by-step explanation:

Arteries

They have thick walls

They blood from the heart to the parts of the body

All the arteries carry oxygenated blood except the pulmonary artery which carries deoxygenated blood from the heart back to the lungs

Arteries do not have valves

Veins

Veins don't have thick walls, that is veins have thin walls

Veins carry blood from the parts of the body to the heart

All the veins carry deoxygenated blood, expect the pulmonary vein which carries oxygenated blood to heart

Veins have valves, to prevent the back flow of blood and allows the blood to flow only in one direction
