The integumentary system is the first line of defense for
the body. The skin covers the surface of the body, protecting
it from invading organisms, chemicals, UV light, and
water loss. Hair and nails also serve as protective barriers. In addition, the skin helps regulate body temperature. This
system plays an important role in diagnostic testing, including
allergy testing and tuberculosis screening. Understanding
this system can help you be more effective in
your role as a medical assistant. |
