The centralportion of the stomach is called the "body", and is outlined by the greater and lesser. Theinferior portion of the stomach is called thewhich contains a sphincter that regulatesmovement of chyme to the small intestine. Generally, it only moves abouthere) of chyme at a time, to allow the duodenum to fully process the chyme. Similar to the otherstructures comprising the alimentary canal, the stomach has 4 tissue layers.ml (write a numberhas numerousthat contain specialized cells that produce theThegastric juice.in these glands that produce alkaline mucus. This mucusserves to coat the mucosa layer, protecting it from the acid. If the mucosa layerbecomes infected, mucus production declines, and the mucosa layer begins to have). The only cure to this problem is antibiotic medicationsThere are manyacid burns (known asto cure the infection.in these glands produce the hydrochloric acid, resulting in the acidic nature ofinto agastric juice. The acid not only dissolves food particles, it also convertsmore absorbable form. These cells also produceabsorption of vitamin B12.,,which is important for thesecrete gastric lipase and the zymogen pepsinogen.The muscularis externa layer is unique in the stomach. Throughout the alimentary canal, the muscularisexternal layer has a longitudinal andlayer of muscle. In the stomach, however, there is anadditionallayer. This third muscle layer is necessary because the stomach is performing a lotofdigestion while combining food with gastric juice to produce chyme.

The mechanism of digestion involves the break-down of the large and complex food molecules into a…
