Digesting Kfc

Digesting KFC

Form the second you start chewing on all those potato strips, the chicken pot pie, the pecan pie, and drinking all 32oz of that soda, you are beginning the digestion process. When food enters the mouth it is partly broken down by the process of chewing and by the salivary enzymes. These enzymes are produced by the salivary glands and break down starches into smaller maltose molecules. Many of the starches from the potato strips, pecan pie, and chicken pot pie with be broken down in the mouth. The sugars from the soda do not get a chance to be broken down in the mouth because it only spends a short time in the mouth before being swallowed. After being chewed and swallowed, the food passes the epiglottis and larynx, and then enters the esophagus. Food in the esophagus is called bolus. The esophagus is a long tube that runs from the mouth to the stomach. It uses rhythmic, wave-like muscle movements called peristalsis to force food from the throat into the stomach.
Before food enters the stomach it passes the lower esophageal sphincter.   Once the delicious KFC enters the stomach, the stomach secretes gastric juices from the gastric gland. The gastric gland has three types of cells. Mucus cells secrete mucus which protects the lining of the stomach, chief cells chief cells secrete pepsinogen which is the inactive form of pepsin, and the parietal cells secrete hydrochloric acid. Gastrin stimulates the gastric juices, which are made up of a mixture of digestive enzymes and Hydrochloric acid. The mixture of food and gastric juices in the stomach is called chyme. The stomach can also physically break down chyme by using its muscles to churn its contents. The HCL has a pH of about 2, and it acidity denatures the proteins the hold the food together. The enzyme pepsin also helps break down proteins in the stomach. The many of the proteins found in the chicken pot pie, potato wedges and the pecan pie will be denatured in the stomach.   Depending on the type...
