WebbThe small intestine is divided into the duodenum, jejunum, and ileum. The small intestine follows the general structure of the digestive tract in that the wall has a mucosa with simple columnar epithelium, submucosa, smooth muscle with inner circular and outer longitudinal layers, and serosa. WebbCastor oil is transformed into ricinoleic acid in the gut, which subsequently irritates, inflames, and releases inflammatory mediators including prostaglandins and histamine into the intestinal mucosa. 39,40 The ensuing prostaglandin production promotes vasodilation, mucus secretion, and smooth muscle contraction in the small intestines. … WebbGastrointestinal smooth muscle contractility is a highly integrated process, in that smooth muscle cells are the final terminals of several modulatory inputs from neurons, … on the house property sales history
