Exocrine gland is a compound term used to describe a type of gland that has ducts that lead to their target destination. The term exocrine is derived from the Greek word "exo," which means "outside," indicating the gland's ability to secrete outside the body through ducts. There are various synonyms for exocrine gland, including external gland, secretory gland, duct gland, and exocrine organ. All of these terms refer to the same type of gland that secretes externally. Exocrine glands play essential roles in regulating bodily functions, such as digestion and lubrication. Their secretions can range from enzymes to sweat and tears, highlighting the diversity and importance of these glands.
