| Role | The artery carries oxygenated blood away from the heart. | Veins carry deoxygenated blood towards the heart. |
| Colour | Red in colour, as they carry oxygenated blood. | Blue in colour, as they carry deoxygenated blood. |
| Location | Arteries located deep within the body. | Veins are present close to the skin, in the body. |
| Kind of blood | Oxygenated blood, except pulmonary artery. As pulmonary artery carries deoxygenated blood. | Deoxygenated blood except for pulmonary veins. As pulmonary veins carry oxygenated blood. |
| Lumen | Narrow lumen. | Broad lumen. |
| Wall | Thick walled, which is more elastic. | Thin walled and are less elastic. |
| Tunica | Externa tunica is less strong and less developed. | Here externa tunica is more strong and more developed. |
| Media tunica is more muscular and thick. | Media tunica are less muscular and relatively thin. |
| Types | Pulmonary and Systemic artery. | Superficial veins, deep veins, pulmonary veins and systemic veins. |
| Muscles tissues layer | Thick layer that supports the high pressure of blood. | It has the thin layer. |
| Blood pressure | More. | Less. |
| Blood volume | Low, which is around 30%. | High, which is around 65%. |
| Pulse | Detectable in the artery. | Undetectable in veins. |
| Valves | No valves. | Valves present. |
| Disease | The main disease affecting the arteries is Atherosclerosis. | The main disease affecting the veins is Deep vein thrombosis. |
| Side effect | If the blood flow stops, it will collapse. | As it has the thick muscular layer, it would remain open even if the flow of blood stopped. |
