Difference between arteries and veins

Definition of arteries

Arteries are blood vessels that carry oxygenated blood away from the
heart and to the body tissues.

Definition of Vein

A vein is a blood vessel that carries deoxygenated blood (blood that is
low in oxygen content) from the body back to the heart.

Difference between arteries and veins

Arteries	Veins
Arteries carry oxygenated blood, away from the heart except pulmonary artery.	Veins carry deoxygenated blood, towards the heart except pulmonary veins.
These are mostly deeply situated in the body.	These are superficial and deep in location.
These are thick-walled, highly muscular except arteries of cranium and vertebral column.	These are thin-walled.
These posses narrow lumen.	These posses wide lumen.
Valves are absent.	Valves are present which provide unidirectional flow of blood.
These are reddish in colour.	These are bluish in colour.
These show spurty movement of blood giving pulse.	These show sluggish movement of blood.
Blood in arteries moves with pressure.	Blood in veins moves under very low pressure.
Arteries empty up at the time of death.	Veins get filled up at time of death.
If arterial wall is injured, the blood comes out like a ‘fountain’ in a large area all around the artery.	If venous wall is injured, blood comes out, collects in a pool in a small area around vein.
