Which is a function of the skin?

• A. Pressure and Pain Perception
• B. Metabolic Coordination
• C. Digestive Function
• D. Hormone Production

Answer: (A)

The skin’s ability to sense touch, pressure, and pain is its key function here. It contains specialized receptors and nerve endings that respond to mechanical stimuli and potential injury. When you press on the skin or feel something sharp, these receptors—like Pacinian and other mechanoreceptors, along with pain receptors—send signals to the brain, letting you perceive pressure and pain. This sensory feedback helps protect you from harm and guides how you interact with your surroundings. The other listed roles belong to different body systems: digestion is handled by the gastrointestinal tract, and hormone production is mainly the job of endocrine glands. (The skin does contribute to vitamin D synthesis under UV light, but that’s not the same as metabolic coordination.)
