What is one of the main functions of sweat glands?

• A. Secrete melanin
• B. Regulate body temperature
• C. Produce keratin
• D. Enhance skin pigmentation

Answer: (B)

One of the primary functions of sweat glands is to regulate body temperature. When the body heats up due to external temperatures or physical activity, sweat glands release sweat onto the skin's surface. As the sweat evaporates, it cools the skin and helps to lower body temperature, which is vital for maintaining homeostasis. This thermoregulatory function of sweat glands is particularly important in preventing overheating and ensuring the body can function effectively during various activities. Other choices, while they pertain to skin and body functions, do not relate to the specific role of sweat glands in temperature regulation.
