    The main job of the small intestine is to break down digested material (assimilation) with the use of chemicals in order to break down large molecules of food into little molecules and to absorb most of the nutrients from everything we eat or drink through the intestine walls via the process of diffusion. As written in IvyRose Holistic website, “Digested material may be transported into blood vessels in the wall of the small intestine by the processes of simple/passive diffusion, facilitated diffusion, primary active transport, or secondary active transport.” (2016, para. 12). So digestion means the process where food and drink are broken down into very small pieces in order for the body to be able to use them sustain cells and for energy.…

    The body makes secretin when chyme enters the duodenum of the small intestines. Like others, secretin is made by special cells in the duodenum. As we have learned for some of the other hormones, secretin targets the stomach to make less enzymes and acid, and to make the mixing action slow down. More importantly, though, secretin also causes the liver to make more bile, while causing the pancreas to make bicarbonate ions. Bicarbonate ions are very important for the duodenum because in order…
