Transcript text: From the following list, select the function that is NOT associated with the skin.
temperature regulation
protection against microbes
synthesis of vitamin E
protective barrier against water loss
sensory input
Solution
The answer is the third one: synthesis of vitamin E.
Explanation for each option:
Temperature regulation: The skin plays a crucial role in regulating body temperature through mechanisms such as sweating and vasodilation or vasoconstriction of blood vessels.
Protection against microbes: The skin acts as a physical barrier to prevent the entry of pathogens and has immune cells that help in defending against infections.
Synthesis of vitamin E: The skin does not synthesize vitamin E. Vitamin E is obtained through the diet and is an antioxidant that helps protect cells from damage.
Protective barrier against water loss: The skin prevents excessive water loss through its outermost layer, the stratum corneum, which is rich in lipids.
Sensory input: The skin contains various receptors that detect touch, pressure, pain, and temperature, providing sensory input to the nervous system.
Summary:
The function that is NOT associated with the skin is the synthesis of vitamin E.
