any of the fine branching blood vessels that form a network between the arterioles and venules.
capillaries
The capillaries are contained within the dermis and and nutrients that the epidermis requires diffuses up to it.
no...you see blood.
capillaries
they provide heat
extremes of temperature alternating heat and cold often leads to the formation of broken capillaries. these appear as fine red lines on white skin, and discolouraiton on black skin.
It is possible to see capillaries through your skin if your skin is thin and pale.
If you scratch your self to hard you cause the capillaries in your skin to break. Capillaries are the smallest of all blood vessels and when broken cause the blood to surface.
No. They are vessels composed of epithelial cells (endothelium) which contain no contractile material. However, at their site of origin they contain sphincters (precapillary sphincters) that controls the flow of blood that enters the capillaries.
It constricts the capillaries and reduces the flow of blood to the skin surface, causing dry skin and wrinkles.
veins
so that our poo has better texture
