1. Noun:
   • A gland that secretes externally through a duct: An "exocrine gland" is an organ that produces and releases substances, such as sweat, saliva, or digestive enzymes, onto an epithelial surface (like the skin or the lining of the digestive tract) via a tube-like structure called a duct.

Usage Examples
