We will begin the tour by entering the oral cavity. The mouth is a hollow chamber with a roof, a floor, walls, teeth for grinding food, and is lined with mucous membrane. The mucus produced by the lining of the GI tract protects the epithelium from digestive juices and lubricates food passing through the lumen. Digestion starts in the mouth before you even take the first bite of the meal. The smells trigger the salivary glands to secrete saliva. (Mohan, 2010). There are three pairs of salivary glands; they are the parotids, submandibular, and sublingual’s. (Thibodeau & Patton, 2008). The saliva increases when you actually taste the food. Once you start chewing and breaking the food down more saliva is produced to begin the process of breaking down food into a form your body can absorb and use. Foods undergo three kinds of processing in the body: digestion, absorption, and metabolism. (Mohan, 2010). Our first stop past the...

- Digestive System The digestive system is a very large system in our bodies. This system runs all the way from the mouth, where we put whole food in, to the large intestine that includes the rectum and anus, where waste exits. The digestive system is composed of the mouth, esophagus, liver, stomach, gallbladder, pancreas, small intestine, large intestine, rectum, and anus (Diseases). The gastrointestinal (GI) tract that makes up the digestive system includes all of these organs other than the liver, pancreas, and gallbladder, which are digestive accessory organs that food does not have to pass through to be broken down (The Digestive Sytem and Body Metabolism)....

- The digestive system is a myriad of organs functioning together to turn food into energy and basic nutrients to nourish the whole body. Food passes through a long tube on the inside of the body which is known as the alimentary canal or the gastriontestinal tract. Digestion begins in the mouth. The process begins way before food comes in contact with the stomach. When a smell that pleases our senses (smell, taste or imagining a delicious snack) the salivary glands, which are below the tongue and near the mandibular jaw, start producing saliva....

- Overview of the Digestive System The purpose of the digestive system is to hydrolyze macromolecules to their smallest subunits. The organs of the digestive system are located within the GI tract. The digestive track is made up of a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The process of digestion requires ingestion, digestion, movement, absorption, and elimination. All parts of the tract have four layers. These layers surround the lumen, or interior space of the GI tract.... [tags: Digestion, Stomach, Digestive system]
