Which of the following is a function of sweat glands?

• A. Aids digestion
• B. Helps dissipate excess heat
• C. Regulates blood sugar
• D. Produces hormones

Answer: (B)

Sweat glands regulate body temperature through evaporative cooling. When sweat is produced and reaches the skin, its evaporation absorbs heat from the body, helping to dissipate excess heat and keep body temperature within safe limits during activity. This cooling mechanism is central to how the body maintains performance and comfort during sport massage contexts.

Aids digestion, regulates blood sugar, and produces hormones are functions of other systems: digestion relies on the digestive tract and enzymes, blood sugar regulation involves the liver and pancreas, and hormone production comes from endocrine glands. So the function tied to sweat glands is dissipating excess heat.
