What are the primary functions of the skin?

• A. Absorption of nutrients
• B. Homeostasis and protection
• C. Repair of internal organs
• D. Production of hormones

Answer: (B)

The primary functions of the skin include maintaining homeostasis and offering protection. Homeostasis refers to the skin's role in regulating body temperature, preserving hydration, and keeping the body's internal environment stable. For instance, when the body overheats, the skin's sweat glands produce sweat that cools the body down through evaporation. Additionally, the skin acts as a barrier against external environmental factors such as pathogens, chemicals, and physical abrasions, thereby protecting underlying tissues and organs. While absorption of nutrients can occur to some extent through the skin, it is not a primary function, as the skin's composition limits how much can be absorbed compared to other systems in the body. The repair of internal organs is primarily the function of specific organ systems rather than the skin. Similarly, while some hormones are produced by the skin, the production of hormones is not one of its main functions; this role is largely managed by endocrine glands throughout the body. Hence, the focus on homeostasis and protection underscores the essential roles that the skin plays in overall health and well-being.
