Endocrine cells secrete hormones directly into the bloodstream, allowing these chemical messengers to travel to distant target organs and regulate various physiological processes. In contrast, exocrine cells produce secretions that are released through ducts to specific locations, such as enzymes in the digestive system or sweat on the skin surface. This fundamental difference in secretion pathways defines their roles in the body’s regulation and function.

What is the major difference between exocrine and endocrine glands?
I think the student wanted to ask about the difference between an exocrine and endocrine gland but mistakened and wrote both the same. Exocrine gland differ from Endocrine gland because in case of exocrine glands ezymes are secreted by ducts carrying them to their site of actions but in case of endocrine hormones are secreted in body without ducts and are cariied by circulatory fluid of the organism.
Do the pancreatic islets secrete their hormones into the same duct system by the exocrine secretory cells?
No, the pancreatic islets, which contain endocrine cells secrete hormones directly into the bloodstream, while the exocrine secretory cells secrete digestive enzymes into ducts that eventually empty into the small intestine.
What are the four types of endocrine cell in pancreatic islets?
The four types of endocrine cells in the pancreatic islets, also known as the islets of Langerhans, are alpha cells, beta cells, delta cells, and pancreatic polypeptide cells. Alpha cells produce glucagon, which raises blood glucose levels; beta cells secrete insulin, lowering blood glucose levels; delta cells release somatostatin, which regulates the endocrine system and inhibits insulin and glucagon secretion; and pancreatic polypeptide cells produce pancreatic polypeptide, which is involved in regulating both endocrine and exocrine pancreatic function.
What type of cells create exocrine secretion?
Exocrine secretions are produced by specialized cells within exocrine glands, such as acinar cells in the pancreas and mucous cells in the salivary glands. These cells are responsible for synthesizing and releasing substances into ducts or the external environment.
Which system regulates chemical activity in the body?
The endocrine system regulates chemical activity in the body through the release of hormones. These hormones travel through the bloodstream and act on target cells to regulate various physiological processes such as metabolism, growth, and reproduction.
Name the exocrine gland that has both endocrine and exocrine functions?
The pancreas has both endocrine (glucagon-alpha cells and insulin-beta cells secretion) and exocrine (digestive enzymes) functions.pancreas

What are the mixed endocrine-exocrine organs?
One of the mixed endocrine-exocrine organs is the pancreas. It has a mixture of the two tissues. The larger, exocrine part has clusters of secretory cells that form sacs known as acini. The smaller endocrine tissue is known as the islets of Langerhans, which go throughout the entire pancreas. The other endocrine organs that are mixed glands are the ovaries and the testes. Mixed glands means that they are endocrine and exocrine in function.
What kind of gland is pancreaes?
The pancreas has both endocrine and exocrine gland cells so it is a mixed gland.
Is insulin secreted by endocrine or exocrine glands?
Insulin is synthesized in significant quantities only in beta cells in the pancreas.
Do the pancreatic islets secrete their hormones into the same duct system by the exocrine secretory cells?
No, the pancreatic islets, which contain endocrine cells secrete hormones directly into the bloodstream, while the exocrine secretory cells secrete digestive enzymes into ducts that eventually empty into the small intestine.
What is the difference between endocrine and exocrine glands?
Endocrine glands secrete their hormones directly into the bloodstream. Exocrine glands secrete their hormones into a duct that leaves the body externally: for example, sweat glands empty onto the skin. Endocrine gland secretes compounds (hormones) into the blood. Exocrine gland secretes compounds outside of the body (including into the GI tract since the GI tract is topologically outside of the body). Exocrine glands have ducts that carry their secretory product to a surface. These glands include the sweat, sebaceous, and mammary glands and, the glands that secrete digestive enzymes.The endocrine glands do not have ducts to carry their product to a surface. They are called ductless glands. The word endocrine is derived from the Greek terms "endo," meaning within, and "krine," meaning to separate or secrete. The secretory products of endocrine glands are called hormones and are secreted directly into the blood and then carried throughout the body where they influence only those cells that have receptor sites for that hormone.
Are endocrine and exocrine glands classified as epithelium because they develop from epithelial membranes?
Yes, endocrine and exocrine glands are classified as epithelium because they are derived from epithelial cells during development. These glands maintain an epithelial lining even after they have differentiated into glandular tissue.
What is cause of pancreas problems in dogs?
As in most mammals, in the dog the pancreas is a digestive organ. The pancreas has two intermingled types of cells - exocrine cells and endocrine cells. The exocrine cells make digestive enzymes that are excreted into the small intestine when food moves out of the stomach. The endocrine cells make insulin and a few other hormones; these are secreted into the blood stream when blood sugar increases.
Which of the endocrine gland is the biggest?
pancreas which is present in the abdominal cavity close to the stomach is the largest endocrine gland. it is endocrine and exocrine in function. it's main bulk is exocrine as it produces pancreatic juice which helps in digestion. then groups of cells called islets of Langerhans are endocrine in function. they produce 2 hormones one is Insulin and the other Glucagon. these both are opposite in function. they maintain a proper glucose level in the blood.
What organs have endocrine and exocrine function?
There is more than one organ that has both endocrine and exocrine functions. The pancreas houses two distinctly different tissues. The bulk of its mass is exocrine tissue and associated ducts, which produce an alkaline fluid loaded with digestive enzymes which is delivered to the small intestine to facilitate digestion of foodstuffs. Scattered throughout the exocrine tissue are several hundred thousand clusters of endocrine cells which produce the hormones insulin and glucagon, gastrin, and somatostatin, plus a few other hormones. The liver also has both endocrine and exocrine functions. The liver's exocrine function involves the secretion of bile, which moves through ducts to the gallbladder where it is stored until needed to emulsify fats. In addition, the liver produces the hormone insulin=like growth factor 1 (IGF-1), which affects growth and development in childhood and impacts adult muscle development as well. The liver also produces the endocrine hormone thrombopoeitin, which stimulate the production of platelets. It makes angiotensinogen, a hormone that affects blood pressure. The stomach secretes stomach acid (exocrine) as well as gastrin (an hormone that works within the stomach). The duodenum secretes mucus (exocrine) as well as gastrin, cholecystokinin, and secretin (endocrine). While the testicles and ovaries do have endocrine function, they produce no exocrine secretions.
What are the four types of endocrine cell in pancreatic islets?
