What structure in the skin is responsible for supplying nourishment and removing waste?

• A. Capillaries
• B. Fat cells
• C. Lymph vessels
• D. Hair follicles

Answer: (C)

The structure in the skin responsible for supplying nourishment and removing waste is the lymph vessels. These vessels play a critical role in the lymphatic system, which is integral to maintaining fluid balance in tissues, transporting immune cells, and processing waste products from the skin and other tissues. They collect excess interstitial fluid and return it to the bloodstream, helping to clear metabolic waste and provide a pathway for nutrients and immune cells.

Capillaries also contribute to nutrient delivery and waste removal; however, their primary role is in the circulatory system, where they facilitate the exchange of oxygen, carbon dioxide, and nutrients directly to and from the blood. Fat cells primarily serve as energy storage and insulation, while hair follicles are involved mainly in hair growth and do not have a direct role in nutrient supply or waste elimination. Therefore, the function of lymph vessels distinguishes them as the correct answer in the context of waste removal and nourishment in the skin.
