Epithelia primarily involved in secretion are arranged into structures known as glands. They are organs that secrete substances into the body for use or discharge. Glands are invaginations of epithelial tissue and can be divided into two main types: Exocrine glands and endocrine glands.

Exocrine glands release their secretions onto an epithelial surface via a duct. Endocrine glands release their secretory products directly into the bloodstream, rather than via a duct.

The glands of the human body fulfill a vast amount of vital functions, and in this introductory video tutorial we will go over the anatomy and purposes of the main glands:
