How might a healthcare provider differentiate between Crohn's disease and ulcerative colitis (UC)? Crohn's disease only affects the small intestine; UC only affects the large intestine. O Endoscopy would show evidence of Crohn's disease, but not UC. Crohn's disease affects all tissue layers; UC only affects the mucosal layer. All of these accurately reflect differences between Crohn's disease and UC 1 pts

Figure 34.11 Which of the following statements about the digestive system is false? Chyme is a mixture of food and digestive juices that is produced in the stomach. Food enters the large intestine before the small intestine. In the small intestine, chyme mixes with bile, which emulsifies fats. The stomach is separated from the small intestine by the pylloric sphincter.

Explain the differences between the digestion roles of the small and large intestines. Does the appendix also have a digestive function?

Figure 34.12 Which of the following statements about the small intestine is false? Absorptive cells that line the small intestine have microvilli, small projections that increase surface area and aid in the absorption of food. The inside of the small intestine has many folds, called villi. Microvilli are lined with blood vessels as well as lymphatic vessels. The inside of the small intestine is called the lumen.

Throughout its length, the alimentary tract is composed of the same four tissue layers; the details of their structural arrangements vary to fit their specific functions. Starting from the lumen and moving outwards, the first three layers are the mucosa, submucosa, and muscularis. The final layer is either the serosa or the adventitia, depending on the portion of the GI tract you are looking at. The mucosa is referred to as a mucous membrane, because mucus production is a characteristic feature of gut epithelium. The membrane consists of the epithelium, lamina propria, and muscularis mucosa (not to be confused with the muscularis externa, described later). Epithelium—This layer is in direct contact with ingested food. In the mouth, pharynx, esophagus, and anal canal, the epithelium is primarily a non-keratinized, stratified squamous epithelium. In the stomach and intestines, it is a simple columnar epithelium. Interspersed among the epithelial cells are mucus-secreting goblet cells.…

Its frequency is the same in each intestinal segment.d. It is unaffected by cephalic phase stimuli.e. It produces a slow migration of chyme to the large intestine.
