In which gland are the islets of langerhans
WebThe pancreas is both an exocrine (compound acinar) and an endocrine (islets of Langerhans) gland. The exocrine pancreas releases alkaline secretions, containing enzymes, into the duodenum that aid in food digestion and neutralize the acidity of chyme leaving the stomach. The islets synthesize hormones that regulate blood glucose levels. 40x. WebThe dimensions of the islets of Langerhans are 50 to 500 microns, and there are between ten and 20 islets per mg of gland tissue. The islets do not communicate with the gland’s effluent ducts. The islets of Langerhans develop from tubular processes of the anterior gut and, depending on the type of animal, consist of cells of several types.
