 Exocrine gland - Wikipedia, the free encyclopedia
Exocrine gland refers to glands that secrete their products and temporarily store their secretions in a duct.
Exocrine glands are named apocrine, holocrine gland, or merocrine gland based on how their product is secreted.
Apocrine gland is often used to refer to the apocrine sweat glands.

The endocrine glands, e.g., the thyroid, adrenals, and pituitary, produce hormones that are secreted directly into the bloodstream (see endocrine system).
Some glands have dual functions, e.g., the liver, pancreas, ovary, and testis produce both a secretion that is emitted through a duct and a hormone that is taken up by the blood.
There are specialized exocrine glands in the animal world that produce such substances as the shells of bird eggs, spiderwebs, and the cocoons of the silkworm larvae.

Structurally, the pancreas is a compound, acinar, serous, exocrine gland with scattered islets of endocrine tissue.

The major endocrine characteristics of the hypothalamus and pituitary gland, the thyroid gland, the parathyroid glands, the adrenal glands, the pancreas, the ovaries and testes, the pineal gland, and the thymus are described in detail.
The thyroid gland is innervated by postganglionic fibers from the superior and middle cervical sympathetic ganglia; the preganglionic fibers of these ganglia emerge from the second through seventh thoracic segments of the spinal cord.
The parathyroid glands are innervated by the thyroid branches of cervical sympathetic ganglia.

Serous and Mucous Exocrine Secretory Cells: In general, the secretory cells of the liver, pancreas, and parotid gland are exclusively serous, while the submandibular and sublingual glands contain a mixture of serous and mucous cells (see Chapter 4).
Intercalated ducts are the smallest ducts in a gland, with a narrow lumen that is continuous with the lumen of the acini.
Structure and Location: These exocrine glands occur in all thin skin, most often in association with hair follicles into which their ducts empty, but are most numerous in the skin of the face, forehead, and scalp.

The liver is a unique structure in that it has exocrine function in terms of bile processing and secretion, endocrine function in terms of synthesis and secretion of serum proteins, and metabolite processing in terms of further processing of adsorbed glucose, amino acids, fatty acids, and detoxification of substances.

Although most glands give the appearance of being "solid" tissue, their epithelial nature is expressed by the organization of their cells, with each cell attached laterally to its neighbors.
In most glands, the secretory cells are organized into secretory units, which are described according to their shape as tubules, acini, or cords.
Other tubular glands include gastric glands (in the lining of the stomach), uterine glands, and various mucous glands of the GI system.

CF is a disease of exocrine gland function, involving multiple organ systems and chiefly resulting in chronic respiratory infections, pancreatic enzyme insufficiency, and associated complications in untreated patients.
Resultant reduced height of epithelial lining fluid and decreased hydration of mucus results in mucus that is stickier to bacteria, which results in infection and inflammation.
For individuals with CF, the lungs are normal in utero, at birth, and after birth, before the onset of infection and inflammation (except possibly for the presence of dilated submucosal gland ducts in the airways).
