This function of the skin aids in maintaining the skin's moisture and elasticity:

• A. Protection
• B. Heat regulation
• C. Secretion
• D. Sensation

Answer: (C)

Secretions from the skin’s glands are what supply moisture and keep the surface supple. Sebaceous glands release sebum to lubricate and protect the skin’s barrier, while sweat adds surface moisture. This combination helps maintain hydration and flexibility, keeping the skin soft and elastic. Other skin functions—protection mainly forms a barrier, heat regulation relies on cooling via sweat, and sensation involves nerves—do not directly provide ongoing moisture and pliability in the way glandular secretions do.
