Which system is involved in regulating body temperature through sweat glands?

• A. Respiratory system
• B. Cardiovascular system
• C. Integumentary system
• D. Nervous system

Answer: (C)

The integumentary system is integral to regulating body temperature through sweat glands. This system includes the skin, hair, nails, and associated glands. When the body temperature rises, the hypothalamus in the brain signals the sweat glands to produce sweat. As the sweat evaporates from the skin's surface, it helps cool the body, thus maintaining a stable internal temperature. The other systems listed play roles in overall bodily functions but are not directly responsible for temperature regulation in the same way. For instance, the respiratory system involves gas exchange, the cardiovascular system is primarily concerned with blood flow and nutrient delivery, and while the nervous system does coordinate signals for temperature regulation, the specific mechanism of sweating is a function of the integumentary system itself.
