FIGURE 8

Cholecystokinin (CCK) is released by specific enteroendocrine cells following entry of food into the duodenum. CCK released into the blood or acting locally on enteric nerves exerts several effects that together coordinate important postprandial responses. CCK activates CCK-1 receptors located on the gastric fundus and pyloric sphincter, respectively, causing relaxation of the stomach and contraction of the sphincter, which together reduce the entry of food in the duodenum. CCK acts on the pancreas to stimulate both exocrine and endocrine secretion. Used with permission from Curr Opin Endocrinol Diabet Obes 14:63–7, 2007.
