EXOCRINE GLANDS

• The exocrine gland consists of a secretory portion and a duct.
• The secretory portion is arranged as a cluster of secretary cells known as a secretory unit, which has a central lumen, which opens into the first portion of the ductular system.
• The exocrine glands can be classified in several different ways based on the shape and form of the secretory unit, nature of secretion and mechanism of secretion.
