Tim has a rare genetic disorder that is characterized by the destruction of the parietal cells. How would this order affect Tim's digestive processes
Step by step
Solved in 2 steps
- Trey has cystic fibrosis, a genetic disorder that is characterized by the production of excessive mucus, affecting several body systems (e.g., respiratory, digestive, reproductive). In the digestive system, the excess mucus blocks bile ducts in the liver and pancreatic ducts. How would this affect Trey’s digestive processes?Barb suffers from Crohn’s disease, a regional inflammation of the intestine that is thought to have some genetic basis, although the actual cause remains unknown. When the disease flares up, she experiences abdominal pain,weight loss, and anemia. Which part(s) of the intestine is (are) probably involved, and what might be the causes of her signs and symptoms?why does pernicious anemia cause a lack of pepsin
- Alexandra experienced vomiting and diarrhea and was diagnosed with gastroenteritis (stomach flu). What specific digestive system organs were affected by the illness?Jim’s jaundice is caused by the accumulation of bilirubin in his blood and tissues. What is the normal fate of bilirubin, and what role does the liver play? Explain how cirrhosis is related to Jim’s jaundice.During your lifetime you may have known individuals (or maybe even yourself) who had various digestive disorders or difficulties such as diverticulitis, ulcers, diarrhea, irritable bowel syndrome, Crohn’s disease, Celiac sprue (gluten intolerance), constipation, choking, or a related disorder. Select one of these digestive issues and discuss the following: Provide a brief description of the digestive issue you will be discussing Describe the experience of the individual – discuss their symptoms, any dietary changes that were required, and the outcome and/or prognosis Describe the related scientific treatments and nutritional treatments of this digestive disorder.
- As Lorraine is listening to Mr. Volpe's complaints she automatically visualizes the organs in the epigastric region that are the potential source of his problems. Where is the epigastric region and what organs associated with digestion are located in that area?Bleeding can occur from any part of the GI tract. Describe a possible cause of bleeding in the small intestine and a different cause in the colon. Are there differences in symptoms or presentation in your two examplesThe entire digestive tract contains layers of muscle that contribute to the digestive process. However, these muscle layers are not the same in all parts of the digestive tract. Describe two examples of digestive organs with unique specializations of these muscle layers and how these specializations contribute to the function of the organs where you find them.
- Harold had his gallbladder removed (cholecystectomy). What advice is given concerning his diet that directly relates to the removal of his gallbladder? a. Eat a diet low in protein. b. Avoid meals high in fat. c. Consume a diet low in carbohydrates. d. Eat large meals once a day.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.…Select the best answer or answers from the choices given: The arasympathetic nervous system influences digestion by (a) relaxing smooth muscle, (b) stimulating peristalsis and secretory activity, (c) constricting sphincters, (d) none of these.
