exocrine
(adjective)
Produces external secretions that are released through a duct.
Examples of exocrine in the following topics:
-
Glandular Epithelia
- Glandular epithelium contains glands, either exocrine or endocrine, allowing for secretory function.
- Epithelia can also be organized into clusters of cells that function as exocrine and endocrine glands.
- Exocrine and endocrine epithelial cells are highly vascular.
- There are two major classifications of glands: endocrine glands and exocrine glands.
- Examples of exocrine glands include the sweat glands, salivary glands, mammary glands, the pancreas, and the liver.
-
Types of Cells in the Pancreas
- It is also a digestive, exocrine organ, that secretes pancreatic juice that contains digestive enzymes to assist with digestion and the absorption of nutrients in the small intestine.
- Acinar cells belong to the exocrine pancreas and secrete digestive enzymes into the gut via a system of ducts.
- Pancreatic polypeptide regulates both the endocrine and exocrine pancreatic secretions.
-
Overview of Pancreatic Islets
- The pancreas serves two functions, endocrine and exocrine.
- The exocrine function of the pancreas is involved in digestion, and these associated structures are known as the pancreatic acini.
- Pancreatic polypeptide regulates both the endocrine and exocrine pancreatic secretions.
-
Pancreas
- The pancreas is a dual-function gland, having features of both endocrine and exocrine glands.
- The pancreas as an exocrine gland helps out the digestive system.
-
Histology of the Pancreas
- Acinar cells belong to the exocrine pancreas and secrete digestive enzymes into the gut via a system of ducts.
- The pancreas is a dual-function gland, having features of both endocrine and exocrine glands.
-
Associated Organs
- The pancreas functions as both an exocrine and endocrine.
- The exocrine function of the pancreas is essential for digestion as the produces many of the enzymes that break down protein, carbohydrates, and fats in digestible foods.
- The pancreas is composed of pancreatic exocrine cells, whose ducts are arranged in clusters called acini.
- The exocrine function of the pancreas is controlled by the hormones gastrin, cholecystokinin, and secretin, which are hormones secreted by cells in the stomach and duodenum in response to food.
-
Epithelial Membranes
- Submucosal glands consist of exocrine glands that secrete mucus.
-
Overview of the Endocrine System
- The endocrine system is in contrast to the exocrine system, which features ducted glands that secrete substances onto an epithelial surface; for example, a sweat gland.
-
Sjögren's Syndrome
- Sjögren's syndrome is an autoimmune disease in which immune cells attack and destroy the exocrine glands that produce tears and saliva.
- Sjögren's syndrome, also known as "Mikulicz disease" and "Sicca syndrome," is a systemic autoimmune disease in which immune cells attack and destroy the exocrine glands that produce tears and saliva.
-
Pancreatic Cancer
- The most common type, accounting for 95% of these tumors, is adenocarcinoma, which arises from the exocrine, or digestive, component of the pancreas .
