The pancreatic islets or islets of Langerhans are the regions of the pancreas that contain its endocrine (i.e., hormone-producing) cells. Discovered in 1869 by German pathological anatomist Paul Langerhans. New studies show that the pancreatic islets constitute approximately 4.5% of the pancreas volume and receive 10-15% of its blood flow. The islets of Langerhans are arranged in density routes throughout the healthy human pancreas.
There are about 3 million islets distributed in the form of density routes throughout the pancreas of a healthy adult human, each of which measures an average of about 0.1 mm (109 µm) in diameter.:914 Each is separated from the surrounding pancreatic tissue by a thin fibrous connective tissue capsule which is continuous with the fibrous connective tissue that is interwoven throughout the rest of the pancreas.:914 The combined mass of the islets is 2 grams. Islets of Langerhans can also form super structures called Islet clusters which are composed of small islets that surround large blood vessels. The roundness of islets along the pancreas has also been quantified through the Index of Sphericity method. Thus, the islets closest to the spherical form are mainly found in the pancreas tail whereas the islets farthest from the spherical form are found in the pancreas neck.

Description of the anatomy and physiology of the islets of langerhans, and the actions of insulin and glucagon.
The Pancreas The pancreas is shown here with the foreground highly magnified to reveal its inner anatomy. Ninety-nine percent of pancreatic tissue is composed of acinar glands, which secrete an alkaline digestive juice into the duodenum via the pancreatic duct to help digest food. The endocrine areas of the pancreas, known as the islets of Langerhans, are composed of two major types of cell. The alpha cells secrete the hormone glucagon, and the beta cells secrete insulin, into the bloodstream. These hormones work in opposition to control the blood glucose level. Insulin promotes the uptake and usage of glucose in the tissues, particularly skeletal muscle and fat, and reduces glucose production in the liver. Glucagon has an anti-insulin effect in the liver, increasing glucose relea...

start destroying your type 2 diabetes right now-type2diabetesdestroyer http://tinyurl.com/z6udwnp Diabetes is a disorder of assimilation, use and stockagLe Diabetes is a disorder of assimilation, use and storage of sugars provided in the diet. This translates into a glucose level in the blood (also called glucose) high: this is called hyperglycemia. "type2 diabetes destroyer" Foods are composed of lipids (fats), proteins (such as meat) and carbohydrates (sugars, starch). It is they who provide the bulk of energy needed by the body to function, pass into the intestine, then join the bloodstream. When we eat, the sugar level in the blood increases, carbohydrates are then processed mainly into glucose. Pancreas detects the increase in blood glucose. The pancreatic beta cells, grouped into c...

Pancreatitis: acute pancreatitis and chronic pancreatitis nursing NCLEX review lecture on symptoms, treatment, pathophysiology, diet, and nursing interventions. Pancreatitis is inflammation of the pancreas that can lead to the digestion of the pancreas by its own enzymes and/or irreversible structural damage to the organ. There are two types of pancreatitis: acute pancreatitis and chronic pancreatitis. In acute pancreatitis, there is sudden inflammation of the pancreas due to something that has triggered the digestive enzymes to become activated inside the organ (high amylase and lipase levels will be found in the blood) and the pancreas starts to digest itself and swell. Two common causes of acute pancreatitis include: gallstones obstruction and heavy consumption of alcohol. Typically, ...
