What is the main role of the skin in the body?

• A. Regulation of temperature
• B. Production of hormones
• C. Protective covering against harmful substances
• D. Transportation of nutrients

Answer: (C)

The main role of the skin is to serve as a protective covering against harmful substances. The skin acts as a physical barrier that protects internal organs from pathogens, chemicals, and physical injuries. By forming this barrier, the skin helps to prevent infections and shield the body from environmental hazards such as UV radiation and pollutants. This protective function is crucial for maintaining overall health and serving as the first line of defense in the body's immune response. In addition to its protective properties, the skin also plays a role in other functions such as temperature regulation and sensory perception. While it does have minimal involvement in the production of certain hormones and can contribute to the absorption of some substances, its primary and most critical function remains its role as a barrier to safeguard the body's internal environment.
