The exocrine system consists of glands that secrete substances to lubricate and protect the body These glands include the sweat, salivary, mucous, mammary, gastric, prostate, bile, ceruminous, sebaceous, and lacrimal glands Substances produced by exocrine glands flow through ducts to epithelial surfaces The three shapes of epithelial cells are squamous, columnar The pancreas is both an exocrine accessory digestive organ and a hormone secreting endocrine gland The bulk of the pancreatic tissue is formed by the exocrine component, which consists of many serous pancreatic acini cells These acini synthesize and secrete a variety of enzymes essential to successfully "rest and digest" But don't let the nirvana after a great mealMicroscopic Vascular Anatomy of the Pancreas The islets of Langerhans, which compromise nearly 2% of the total pancreatic volume, are highly vascularized structures within the pancreas, receiving approximately 10fold the blood supply of the exocrine tissue by volume, with the intraislet microcapillary network constituting 78% of the total islet volume (15, 27) ( Figure 1 )

Describe the structure and function of endocrine and exocrine glands and their respective secretions;Also called paracrine factor SolutionsDigestive System > Pancreas Histology of the Pancreas The structure of the pancreas is dominated by the fact that it is a dual function organ with both exocrine and endocrine cell types The vast bulk of the pancreas is composed of exocrine tissue, and secretions from those cells flow into a series ducts for ultimate delivery into the duodenum Scattered within the exocrine tissue
The risk factors for pancreatic exocrine insufficiency after PD The enrolled patients were divided into 2 groups based on the results of the 13 Clabeled mixed triglyceride breath test , as follows the exocrine insufficiency group (n = 97, 513 %) defined by %CD7 h < 5 %, and the normal group (n = 92, 487 %) defined by %CD7 h ≥ 5 % Exocrine Pancreas – The Functional Unit The functional unit of the exocrine pancreas includes the acinus and its duct system The word acinus is from the Latin term for "berry in a cluster" These acinar cells are specialised in enzyme synthesis, storage and secretion The duct system modifies the aqueous secretionsThe endocrine system acts through chemical messengers called hormones that influence growth, development, and metabolic activities The action of the endocrine system is measured in minutes, hours, or weeks and is more generalized than the action of the nervous system There are two major categories of glands in the body exocrine and endocrine
The exocrine function of the pancreas is mainly digestive in nature and involves the secretion of pancreatic enzymes and bicarbonate (Jarvis, 15 & Scanlon, 15) Having knowledge of the structure and functions of the gastrointestinal system will assist in the recognition and interpretation of assessment findings related to the patient's history and physical exam A gland is a functional unit of cells that works together to create and release a product into a duct or directly to the bloodstream Two principal types of glands exist exocrine and endocrine The key difference between the two types is that, whereas exocrine glands secrete substances into a ductal system to an epithelial surface, endocrine glands secrete productsHuman endocrine system, group of ductless glands that regulate body processes by secreting chemical substances called hormones Hormones act on nearby tissues or are carried in the bloodstream to act on specific target organs and distant tissues Diseases of the endocrine system can result from the oversecretion or undersecretion of hormones or
