Differences between arteries and veins on the basis of their structure:
| Arteries | Veins |
|---|---|
| Arteries have thick, elastic and muscular walls to withstand high pressure. | Veins have thin and less muscular walls as the blood pressure is lower. |
| They lack valves (except the pulmonary trunk and the aorta). | Valves are usually present to prevent the backflow of blood. |
| Arteries are usually, deeply placed in the body. | Veins are usually placed more superficially. |
