- List the organs and accessory organs of the digestive system. On a separate piece of paper, list the main functions of each organ.Figure 16.7 Which of the following statements about the digestive system is false? a. Chyme is a mixture of food and digestive juices that is produced in the stomach. b. Food enters the large intestine before the small intestine. c. In the small intestine, chyme mixes with bile, which emulsifies fats. d. The stomach is separated from the small intestine by the pyloric sphincter.Which surgery do you think would have the most profound effect on digestion: (a) removal of the stomach (gastrectomy); (b) removal of the pancreas (pancreatectomy);or (c) removal of the gallbladder (cholecystectomy)? Explain your reasoning.
- There are several processes that take place from the moment food enters our mouth until it is completely digested and used for energy. Using approximately 400-500 words, describe in detail and in order of process the mechanical (stomach and intestine)and chemical (gastric acid and enzymes) digestion of eating a grilled chicken sandwich with mayonnaise, lettuce, and tomatoes. Note what role the pancreas, gallbladder, and liver play in digestion of the ingredients? From what ingredients is your body deriving its energy and how many basic calories from the macronutrients ingested? Include at least two scholarly references (using APA formatting and style) to guide your answers (note that you can use your textbook as one of your references).Consider this statement: "Gastric bypass surgery condemns the recipient to starve to death over many years." Using your understanding of the digestive system, defend or refute the statement. Include: 200-300 words impact of gastric bypass on homeostasis diagram of the digestive system to support your position active enzymes and biological molecules involved in digestion evidence-based argument for your positionDigestion of the macronutrients begins in different parts of the GI tract. Apply what you have learned about the digestive process by showing what the digestive fate will look like for a chicken-mayonnaise toasted sandwich, made with whole wheat seed bread. Remember to discuss the functions and/or type of digestion per organ and the secretions per organ relevant to the digestion of the macronutrients. It is important that your answer is provided in the correct order in which these digestive processes would take place.
- The digestive system is composed of many organs. The organs have their specific functions in the digestion process. For you, what are the importance of knowing the function of the organce?Consider a meal of pancakes with syrup and a side of bacon. Answer the following question. Describe the progression of this meal through the digestive system beginning in the mouth and ending in the colon. Your description should include where mechanical and chemical digestion are occurring as well as an explanation of specifically where the different nutrients/macromolecules that make up the foods are broken down.There are two different kinds of secretions associated with the digestive system that needs to be understood to avoid confusion when describing how the digestive system functions. Which one of these secretions will be involved in the control of digestion through the blood? A.Endocrine B.Exocrine
- 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.Digestion takes place in a long tube-like canal called the alimentary canal, or the digestive tract. Food travels through these organs in the following order: 1) Mouth, gullet, stomach, small intestine,large intestine and rectum 2) Mouth, oesophagus, stomach, large intestine,small intestine and rectum 3) Mouth, stomach, oesophagus, small intestine,large intestine and rectum 4) Mouth, stomach, gullet, small intestine,large intestine and rectumWith the two menus provided, answer the question below: Menu 1: Roasted chicken with mashed potatoes (mostly proteins and carbohydrates) Menu 2: Pasta with alfredo saude and cheese (mostly carbohydrates, dairy products and lipids) Question: Describe the steps in the chemical digestion of the main constituents of your meal (name the enzyme (s) and other secretions involved, and what cells secrete them), all of that from the beginning to the end of digestion.
