_______ and _______ in the Skin are an Important Part

Question

_______ and _______ in the skin are an important part of the body's temperature regulating system.
A) Vitamin D; sweat glands
B) Capillary networks; subcutaneous layer
C) Capillary networks; sweat glands
D) Vitamin D; subcutaneous layer

Accepted Answer

Capillary networks help regulate body temperature by dilating (expanding) or constricting (narrowing) to allow or restrict blood flow to the skin's surface, where heat can be released. Sweat glands also play a crucial role in temperature regulation by producing sweat, which evaporates and cools the skin. Vitamin D is not directly involved in temperature regulation, and while the subcutaneous layer can insulate against extreme temperatures, it does not play an active role in regulating body temperature.
