Which body system helps maintain homeostasis by regulating temperature and electrolyte balance?

• A. The muscular system
• B. The endocrine system
• C. The integumentary system
• D. The respiratory system

Answer: (C)

The integumentary system is crucial in maintaining homeostasis, particularly in regulating body temperature and electrolyte balance. This system includes the skin, hair, nails, and associated glands. Temperature regulation occurs through the sweat glands in the skin, which produce sweat that evaporates, helping to cool the body down. Conversely, when the body is cold, blood vessels in the skin can constrict to preserve heat. This dynamic response ensures the body remains at a relatively constant temperature, which is essential for optimal physiological functioning. In terms of electrolyte balance, the skin plays a role in the excretion of certain electrolytes through sweat, primarily sodium and chloride. By managing the levels of these electrolytes, the integumentary system helps support overall fluid balance in the body, contributing to homeostasis. While the muscular system aids in thermoregulation through shivering and the endocrine system contributes through hormone regulation, and the respiratory system helps manage gas exchange, none of these systems directly interact with temperature and electrolyte balance to the extent that the integumentary system does. Thus, the integumentary system is the primary body system responsible for regulating these aspects of homeostasis.
