- Mr. Johnson has a gallstone (a stone) that completely obstructs the normal flow of bile and pancreatic juice into the duodenum. Explain how the digestion of carbohydrates (polysaccharides and disaccharides), lipids (triglycerides), proteins, and nucleic acids would be affected throughout the digestive tract, starting in the mouth and ending in the microvilli of the cells in the small intestine. Make one paragraph per molecule.arrow_forwardInflammation of the digestive tract is common to most irritable bowel diseases including Crohn’s Disease, IBD Syndrome, and Celiac’s Disease. While each of these diseases causes inflammation by a different mechanism, they all result in decreased capacity to absorb nutrients and minerals. In extreme cases, this can lead to severe diarrhea, malnutrition, osteoporosis (weakening of the bones), and iron deficiency, to name a few. Based on the information above, which region(s) and structure(s) of the alimentary canal is (are) most likely targets of inflammation? Explain your answer based on the roles of each segment of the alimentary canal.arrow_forwardWhen the duodenu is actively digesting food, the Sphincter of Oddi released both bile and pancreatic juice into the duodenum Between meals, when the Sphincter of Oddi is closed, an accessory pancreatic duct remains open, allowing a slow but continual flow of pancreatic juice into the duodenum between meals WHy must there be pancreatic juice in the duodenum even if no food is currently being digested? A- Even if there isnt chyme in the duodenum, stomahc acid might leak into the duodenum. the trypsin in pancreatic juice neutralizes that B- We eat a lot, so we're always digesting food in the duodenum C - the process of fat breakdown is slow, so lipids could stay in the duodenum for over a day, so we need a steady supply of pancreatic lipase. D- Even if there isn't chyme in the duodenum, stomach acid might leak into the duodenum. The bicarbonate in pancreatic juice neutralizes thatarrow_forward
- Fred has been experiencing recurring episodes of heartburn, especially when he bends over to lace his shoes or when he lies down in bed. His physician believes Fred may have a hiatal hernia. To confirm this diagnosis, she has scheduled Fred for a “barium swallow.” In this test, a barium-containing fluid that blocks x-rays is swallowed so that the stomach appears as a bright mass in a radiograph. If Fred has a hiatal hernia, what should the radiologist see on the radiograph? Can you explain what caused the symptoms that brought Fred in to see his physician?arrow_forwardDisorders of the digestive system often disrupt many aspects of homeostasis. Explain why?arrow_forwardMorgan has been overweight for years. Recently, he developed abdominal pain that occurs every few days. The pain usually starts within 30 minutes after a fatty or greasy meal and can last for one to five hours. Preliminary diagnosis indicates stones formation at location X as shown in Figure 1. Liver- X Figure 1 (i) Identify the organ labelled “X". (ii) Analyse why Morgan usually experienced pain within 30 minutes after a fatty or greasy meal. (iii) Suggest two possible treatments for Morgan.arrow_forward
- Jake was having dinner at home with his family after coming back from work. While enjoying his favorite pizza and pasta dishes, he started to feel nauseous and felt pain at his left-upper abdominal region. His family sent him to the emergency department for further checks to determine the problem. At the hospital, Jake was diagnosed as suffering from pancreatitis, which affects the function of his pancreas. Explain how the digestion of major nutrients (carbohydrates, proteins and fats) maybe impacted if the pancreas is unable to function normally. (Include the enzymes and processes that are involved)arrow_forwardThe 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.arrow_forwardIn some severe cases of stomach ulcers, the branches of the vagus nerve (X) that lead to the stomach are surgically severed. How might this procedure control the ulcers?arrow_forward
- What is the danger of excessive amount of cholesterol in bile? Explain why.arrow_forwardAll of the following statements concerning this region of the small intestine are true, EXCEPT for . . . Chooe one from the following: (A) This region of the small intestine is the 2nd longest region (B) Peyer's patches are located in the submucosa of this region of the small intestine (C) This region of the small intestine is classified as intraperitoneal (D) Branches of the superior mesenteric artery supplying this region of the small intestine demonstrate multiple levels of arcades (E) Most of the nutrients available to the body after digestive hydrolysis are absorbed across the wall of this region of the small intestinearrow_forwardDuring 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.arrow_forward
