When a fair-skinned person blushes, why does his or her skin turn red?
The blood supply to the skin increases.
The number of red melanocytes in the skin increases.
Melanocytes increase production of red pigments.
The blood supply to the skin decreases.
In
The blood supply to the skin increases
Stretch marks occur when
the skin is stretched in normal movements.
surgical incisions are made perpendicular to the skin's lines of cleavage.
the skin is so extensively stretched that its elastic capabilities are exceeded.
athletes overextend a muscle.

the skin is so extensively stretched that its elastic capabilities are exceeded.
Skin can regenerate effectively even after considerable damage has occurred because
the epidermis of the skin has a rich supply of small blood vessels.
