[Q]: Paragraph- Sent 1: You couldnt survive without your skin.
Sent 2: It has many important functions.
Sent 3: The main function of the skin is controlling what enters and leaves the body.
Sent 4: It prevents the loss of too much water from the body.
Sent 5: It also prevents bacteria and other microorganisms from entering the body.
Sent 6: The skin helps maintain a constant body temperature.
Sent 7: It keeps the body cool in two ways.
Sent 8: Sweat from sweat glands in the skin evaporates to cool the body.
Sent 9: Blood vessels in the skin dilate, or widen.
Sent 10: This action increases blood flow to the body surface.
Sent 11: This allows more heat to reach the surface.
Sent 12: The heat is then able to radiate off the body.
Sent 13: The opposite happens to retain body heat.
Sent 14: Blood vessels in the skin constrict, or narrow.
Sent 15: This decreases blood flow to the body surface.
Sent 16: This reduces the amount of heat that reaches the surface.
Sent 17: When this happens, less heat can be lost to the air. 
Question: Can skin prevent bacteria from entering the body?.
[A]: Yes.
