The pancreas is an organ of the digestive system and endocrine system of vertebrates. In humans, it is located in the abdomen behind the stomach and functions as a gland. The pancreas is a mixed or heterocrine gland, i.e., it has both an endocrine and a digestive exocrine function. [2] 99% of the pancreas is exocrine and 1% is endocrine.
Ultrasonography [9] – the role of ultrasonography in imaging the pancreas is limited by patient habitus, operator experience and the fact that the pancreas lies behind the stomach (and so a gas-filled stomach will obscure the pancreas). Computerized tomography [10] – this is the gold standard for initial assessment and follow-up.
The pancreas arises as two separate bodies, the dorsal pancreas and the ventral pancreas. The dorsal pancreas appears first, at around day 26, opposite the developing hepatic duct, and grows into the dorsal mesentery. The ventral pancreas develops at the junction of the hepatic duct and the rest of the foregut.
The agenesis of dorsal pancreas can be classified into two classes based on the morphological features: complete and partial agenesis. For the former one, the accessory pancreatic duct (also known as duct of Santorini) as well as the body and tail of the pancreas are missing. [1] For partial agenesis, the tail of the pancreas is still present. [1]
The pancreas is involved in digestion and managing blood sugar. When it's is in trouble, diabetes, pancreatitis, or pancreatic cancer can result. How to care for this organ.
Pancreatitis is a condition characterized by inflammation of the pancreas. [1] The pancreas is a large organ behind the stomach that produces digestive enzymes and a number of hormones. [1] There are two main types: acute pancreatitis, and chronic pancreatitis. [1] Signs and symptoms of pancreatitis include pain in the upper abdomen, nausea and ...
Water follows the movement of these ions. The GI tract accomplishes this ion pumping using a system of proteins that are capable of active transport, facilitated diffusion and open channel ion movement. The arrangement of these proteins on the apical and basolateral sides of the epithelium determines the net movement of ions and water in the tract.
Exocrine pancreatic insufficiency (EPI) is the inability to properly digest food due to a lack or reduction of digestive enzymes made by the pancreas.EPI can occur in humans and is prevalent in many conditions [1] such as cystic fibrosis, [2] Shwachman–Diamond syndrome, [3] different types of pancreatitis, [4] multiple types of diabetes mellitus (Type 1 and Type 2 diabetes), [5] advanced ...
