Answer:
When we exercise the blood capillaries dilate because of the removal of waste products like carbon dioxide from muscles during exercise.
The dilated blood vessels results in the increased blood flow and increased blood flow leads to the delivering of more amount of oxygen to the body muscles and cells during the exercise.
So increased blood flow is necessary for the removal of waste products like carbon dioxide and lactic acid generated during exercise and to deliver the appropriate amount of oxygen to muscles to function properly.

This kind of exposure is called caustic exposure.
Explanation:
A caustic exposure is an exposure to chemicals present in common household cleaning products like detergents, cleaning solutions, drain cleaners etc.
These contain caustic substances (strong concentration of acid or base) like sodium hydroxide, sulfuric acid etc. When exposed directly on to the skin, due to its stronger concentration, it may burn the skin causing redness, irritation, numbness, or blackening of the skin surface.
Most of the times, these marks go away after some weeks because they are superficial or first-degree burn where only the epidermal layer of the skin gets affected.
