The correct answer is a) maintaining normal body temperature.
While the skin plays a crucial role in regulating body temperature through sweat production and blood flow, it is not solely responsible for maintaining normal body temperature. The body has several systems that work together to regulate temperature, including the hypothalamus in the brain, which acts as the body’s thermostat. The skin does contribute to this process, but it is part of a larger system involving various organs and mechanisms.
On the other hand, the skin is indeed responsible for:
- b) storing fat – The subcutaneous layer of the skin contains fat cells that store energy and help insulate the body.
- c) synthesizing vitamin D – When exposed to sunlight, the skin helps convert cholesterol into vitamin D, which is essential for bone health.
- d) detecting sensations – The skin is equipped with various nerve endings that allow us to feel touch, pressure, pain, and temperature changes.
In summary, while maintaining body temperature is a function of the skin, it is not the only or primary mechanism for body temperature regulation.
