sIts a typical day. After learned person you stand home and you are starving, but you mediocre wrong a snack. What should I annihilate?, you ask yourself.

They secrete amylase and mucus. The parotid glands begin chemical digestion on the Cheetos. It secretes a clear, watery liquified that is high in amylase. The enzyme, amylase, begins to dislocation carbohydrates into disaccharides. The other two salivary glands, the submandibular and the sublingual, secrete saliva containing mucus, which binds and lubricates the Cheeto particles for thriving swallowing. Now the pabulum has been create into a bolus with the help of saliva, the tongue, and teeth.

neighboring the bolus travels into the pharynx, where the epiglottis closes off the top of the trachea so no forage can enter. Then it moves on to the esophagus, where peristaltic waves push the viands toward the stomach. The food enters the stomach through the cardiac sphincter at the eff of the esophagus. Now the Cheetos have entered the stomach. The process of breaking belt down carbohydrates has already begun in the mouth and immediately more chemical and robotic digestion will take lieu in the stomach. Once the bolus has entered the stomach, it mixes with stomachal 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
