Functions of the skin include all of the following, except:

• A. Maintenance of water balance.
• B. Sending information to the brain.
• C. Regulation of body temperature.
• D. The production of key antibodies.

Answer: (D)

The production of key antibodies is not a function of the skin. Although the skin plays a vital role in the immune system by acting as a barrier to pathogens and producing antimicrobial peptides, it does not produce antibodies. Antibodies are primarily produced by B cells in the immune system, which are located in lymphatic tissues, not in the skin. In contrast, the skin does serve several crucial functions. It helps maintain water balance by preventing excessive loss of moisture from the body. The skin is also equipped with receptors that send sensory information to the brain, allowing for the perception of pressure, temperature, and pain. Additionally, the skin plays an essential role in regulating body temperature through processes such as sweating and the dilation or constriction of blood vessels.
