Which of the following is NOT a function of the skin?

The function of hormone production is indeed not attributed to the skin. The primary roles of the skin include temperature regulation, which helps maintain the body’s internal temperature through mechanisms such as sweating and altering blood flow; immunoregulation, where the skin acts as a barrier and plays a critical role in the immune response by preventing pathogens from entering the body and producing immune cells; and sensory perception, which enables the body to respond to environmental stimuli through receptors that detect touch, pain, temperature, and pressure.

While the skin does have some minor involvement in the synthesis of certain vitamins, like vitamin D, the production of hormones is primarily a function of glands and organs such as the endocrine glands (like the thyroid or pituitary gland) rather than the skin itself. This clear distinction helps in understanding the various roles that different body systems play, emphasizing that hormone production is typically not a direct function of the skin.
