Digestion

sIts a typical day. After savant you stand home and you are starving, but you just exit a snack. What should I exhaust?, you ask yourself. Then, after nervus facialis expression through the cabinets for a few minutes, you find Cheetos and make up ones mind to eat a few. With just the presence of those Cheetos in your sight, the digestion transit begins in your 9 meter long digestive tract. Crunch, Crunch, Crunch.

Here, windup(prenominal) digestion begins to reduce the size of the Cheeto and mixes the sustenance particles with saliva. The tongue helps mix and moves the pieces of Cheeto throughout the mouth. The salivary glands in the mouth also contribute to the sustain of the Cheetos in the mouth. They secrete amylase and mucus. The parotid glands begin chemical digestion on the Cheetos. It secretes a clear, watery fluid that is high in amylase. The enzyme, amylase, begins to separate car bohydrates into disaccharides. The other two salivary glands, the submandibular and the sublingual, secrete saliva containing mucus, which binds and lubricates the Cheeto particles for well-situated swallowing. Now the pabulum has been formed into a bolus with the help of saliva, the tongue, and teeth.

bordering the bolus travels into the pharynx, where the epiglottis closes off the top of the trachea so no pabulum can enter. Then it moves on to the esophagus, where peristaltic waves push the fare toward the stomach. The food enters the stomach through the cardiac sphincter at the dispatch of the esophagus. Now the Cheetos have entered the stomach. Th! e process of breaking down carbohydrates has already begun in the mouth and now more chemical and reflexive digestion will take place in the stomach. Once the bolus has entered the stomach, it mixes with stomachic juice, starts protein digestion, and absorbs a limited amount. Here the chief cells secrete the dormant(ip) enzyme pepsinogen and the parietal calls secrete hydrochloric acid. The bolus then travels down into the...If you want to get a full essay, order it on our website: OrderCustomPaper.com
