Which is a skin function related to temperature regulation?

• A. Temperature regulation
• B. Oxygen transport
• C. Hormone synthesis
• D. Nutrient absorption

Answer: (A)

Skin regulates body temperature through sweat production and changes in blood flow. When heat builds up, sweat glands release sweat; as it evaporates from the skin, it cools the body. Blood vessels in the skin can dilate to increase heat loss or constrict to conserve heat in cool conditions. Oxygen transport, hormone synthesis, and nutrient absorption aren’t primarily about temperature control—oxygen transport is a circulatory function, hormone synthesis occurs in glands, and nutrient absorption mainly happens in the digestive system.
