Q
  1. When the ambient temperature is high: A) the dermis produces less collagen, which temporarily decreases the skin’s ability to retain warmth. B) blood vessels in the dermis dilate, which increases blood flow to the skin and allows heat to dissipate.

Q
  1. Physical injury to the skin: A) causes a decrease in the production of macrophages and lymphocytes, thus increasing the risk of infection. B) commonly destroys the stratum corneum, the deep dermal layer of the skin, and causes nerve damage.
