In the human body, blood vessels are located differently according to their types.
Tab 1 Arteries
If an artery is injured, the threat to life is greater than with other types of blood vessels.
For protection, arteries tend to be located deep within the structures of the body.
Only the very smallest of arteries, especially the cutaneous arteries, come close to the surface of the body.
Tab 2 Veins
Veins can be located at both deep and cutaneous levels.
The deep veins accompany the arteries side by side.
The cutaneous veins are found in the subcutaneous layer of the body.
The cutaneous veins drain into the deep veins at specific locations (especially the inguinal region and the axillary region).
Tab 3 Capillaries
The capillaries are located throughout all tissues of the body.
No individual cell is more than two cells away from a capillary.
The networks of capillaries in the tissues are often called capillary beds.
