Exocrine gland

A gland with ducts which channel secretions to particular parts of the body such as the liver, the sweat glands, the pancreas and the salivary glands.


Gland that discharges its secretion usually through a duct, to an adjacent epithelial surface, as the sweat glands discharge onto the skin surface. Included among the exocrine glands are the sudoriferous (sweat) glands, sebaceous glands, certain glands involved in digestion (e.g., ducts secreting pancreatic juice in the pancreas), lacrimal (tear) glands, salivary glands, wax-producing glands of the ear, and mammary glands. Also sometimes called duct gland.


A gland that releases substances through a duct or channel onto or into an organ or area of the body. For example, lacrimal ducts secrete tears onto the eye; the salivary glands secrete saliva into the mouth; sweat glands produce sweat on the skin; pancreatic tissue secretes digestive enzymes that are carried through ducts into the intestine. Exocrine secretions may be controlled by hormones or by chemical neurotransmitters that function similarly to hormones.


A gland that discharges its secretion by means of a duct, which opens onto an epithelial surface. An exocrine gland may be simple, with a single unbranched duct, or compound, with branched ducts and multiple secretory sacs. The illustration shows some different types of these glands. Examples of exocrine glands are the sebaceous and sweat glands.


A gland that secretes its products through a duct to the surface of the body or of an organ. The sweat glands in the skin and the salivary glands in the mouth are examples. The secretion is set off by a hormone or a neurotransmitter.


Produce a substance that travels through small tube-like ducts; sweat glands and oil glands of the skin belong to this group.
