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