Exocrine glands
« Back to Glossary Index
  • Exocrine glands secrete substances such as enzymes, mucus, sweat, oil, saliva, and digestive juices. These substances are typically released into ducts that transport them to specific sites within the body or onto epithelial surfaces.
  • Salivary glands secrete saliva, which aids in digestion and maintains oral health.
  • Sebaceous glands produce sebum, an oily substance that lubricates the skin and hair.
  • Sweat glands regulate body temperature and excrete waste products.
