Differences Between Arteries and Veins:
The following are the points of differences between Arteries and Veins.
Arteries | Veins |
---|---|
It generally appears pink. | It is generally dark red in colour. |
Arteries are usually deep-seated. | Veins are usually superficial. |
They carry blood away from the heart into various organs and tissues. | They bring blood from various organs and tissues into or towards the heart. |
They contain oxygenated blood except pulmonary artery. | They contain deoxygenated blood except pulmonary vein. |
Blood flows under pressure. | Blood has low pressure. |
Blood flows with jerks. | Jerks are absent. |
The flow of blood is very fast. | The flow of blood is slow. |
Their wall is thick, strong and less distensible. | Their wall is thin, weak and more distensible. |
Tunica intima coat bears a well-developed layer of endothelium and elastic tissue membrane (elastic lamina). | Tunica intima coat bears a poorly developed layer of endothelium and relatively thin elastic membrane. |
Tunica media coat provides the thickest portion to an artery and consists of more elastic and muscular fibres. | Tunica media coat is poorly developed and its muscular and elastic fibres are fewer. |
Tunica adventitia coat is comparatively less developed and not much thicker. | Tunica adventitia coat is comparatively well developed and much thicker. |
They are non-collapsible due to the presence of thick walls. | They are collapsible due to the presence of thin walls. |
The lumen of arteries is small. | The lumen of a vein is large. |
At any time arteries contain 16% of total blood. | 64% of body blood is present in veins. |
Internal valves are absent. | Internal valves are usually present for preventing backflow. |
They become empty after the death of an animal. | They retain blood even after the death of an animal. |
