उत्तर
| Artery | Veins |
| Arteries are the ones that aid in taking blood away from the heart and to all the tissues of the body. | Veins are responsible for carrying the blood back to the heart. |
| They have thick walls. | Veins have thin walls. |
| Arteries appear red in color as they carry the oxygenated blood. | Veins tend to appear blue in color as they transport deoxygenated blood. |
| The pressure of the blood flowing through arteries is high. |
The pressure here in the veins is low as the blood flows via the help of capillary action exerted by the veins. |
| Arteries are located deep in the body. | Veins are found near to the skin. |
