Question 18

105. Essay: Describe how skin helps maintain body temperature if a person becomes cold/warm.

Answer 18

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

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 smooths out to allow heat out.
