Produce and release substances for specific functions in the body.

• A. Dermis
• B. Epidermis
• C. Glands
• D. Cortex

Answer: (C)

Glands are the structures that produce and release substances for specific functions in the body. They can act as exocrine glands, sending secretions onto surfaces or through ducts—for example, sebaceous glands produce sebum to keep skin and hair lubricated, and sweat glands release sweat to help cool the body and excrete wastes. They can also act as endocrine glands, releasing hormones directly into the bloodstream to regulate various processes. In the skin, glands are responsible for lubrication and temperature control, among other roles, and while the dermis and epidermis provide the environment and support, they’re not the sources of these secretions. The cortex isn’t involved in this secretion function.
