Q
  1. Describe how skin helps maintain body temperature if a person becomes cold.
A

Blood vessels in the skin construct to decrease the amount of blood that flows through them. This allows heat to stay inside body. Sweat glands in the skin reduce perspiration to none. Hairs stand up because the arrestor pili muscle has contracted which produces goose bumps on the skin reducing skin surface area.

Q
  1. Describe how skin helps maintain body temperature if a person becomes warm.
A

Blood vessels in the skin enlarge to increase the amount of blood that flows through them. This allows heat to move from the body into the outside environment. Sweat glands in the skin produce perspiration. As the perspiration evaporates, it carries heat into the air. Hairs on the body lie flat. Skin smoothes out to allow heat out.

Q
  1. What are the two fibers of the dermis?
A

Collagen and Elastin
