Abstract

The pancreas is a retroperitoneal organ containing both exocrine and endocrine function. The key functional unit of the exocrine pancreas is composed of an acinus and its drainage ductule. The pancreas has been the major model used to demonstrate the mechanisms of synthesis and transport for exportable proteins. The fundamental function of exocrine pancreas is to synthesize and secrete digestive enzymes for the processing and assimilation of a meal and transport the digestive enzymes in a ductal system secreting large volumes of a bicarbonate-rich solution. Pancreatic enzyme secretion is primarily coordinately regulated through the neurohormonal pathways. Chronic inflammatory diseases of the pancreas can lead to loss of normal tissue and the inability of the pancreas to secrete sufficient amounts of enzymes for normal digestion and absorption. Also, loss of exocrine pancreatic tissue from surgical procedures can result in pancreatic insufficiency and nutrient malabsorption. This chapter will present a concise illustration of the current understanding of pancreatic physiology and the clinical implications resulting from disease of the pancreas and pancreatic surgery.
