Question 21

Figure 1 shows a cross-section of human skin.

A detailed cross-sectional diagram of human skin showing the different layers: epidermis, dermis, and subcutaneous fat. It labels key structures: hair, hair erector muscle, sweat gland, sweat duct, and blood capillaries near the skin surface.

Explain how structures in the skin function to minimize heat loss and maintain core body temperature when a person is exposed to cold weather.
