ARTERIES VEINS
Functions
Involved in carrying oxygenated blood except for pulmonary arteries Involved in carrying deoxygenated blood except for pulmonary veins
Walls

Position
Located deep within the body. Peripherally located closer to the skin.
Appearance
Red in colour. Blue in colour.
Transports
Carry blood away from the heart to various parts of the body. Carry blood towards the heart from the various parts of the body.
Rate of pressure
High pressure, as the blood flows by the pumping pressure of the heart. Low pressure, as the blood flows by the capillary action of the veins.
Oxygen Level
Comparatively higher oxygen level. Comparatively low oxygen level.
Carbon dioxide Level
The level of carbon dioxide is low The level of carbon dioxide is high
The direction of Blood Flow
In the downward direction from the heart to the body tissues. In the upward direction from the body tissues to the heart.
Lumen
Lumen is narrow. Lumen is wide.
Valves
Valves are absent Valves are present
Disorders

Explanation:
Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation.
