Step by step
Solved in 3 steps
- Which of the following types of movement is responsible for the mixing of food in the GI tract? Group of answer choices Deglutition Mass movement Peristalsis Segmentation In the digestion of lipids, a chylomicron contains Group of answer choices Both monoglycerides and fatty acids Monoglycerides Fatty acids Triglycerides Which of the following components of digestion is responsible for the chemical breakdown of foods? Group of answer choices Chewing Enzymatic hydrolysis Dissolving Emulsification Which of the following is a hormone that stimulates the pancreas to secrete bicarbonate? Group of answer choices Cholecystokinin Secretin Gastrin Glucose-dependent insulinotropic peptideDoes digestion in the GI tract take place extracellularly (outside the cells) or intracellularly (inside the cells)? Explain your answer.What would be the significance of selectively destroying gastric vagal innervations on pepsin production?
- When sensors in the GI tract are stimulated, they respond via reflexes. What types of digestive activity may be put into motion via those reflexes?How does gastrointestinal tract evade dehydration? 1) Alternating wave-like contraction and relaxatio of the oral (mouth) muscles reabsorbs water which will be transported to the urinary system 2) water is an important digestive enzyme in the stomach. 3) Normal peristaltic movements in the large intestine ensure reabsorption of water that will be delivered to the circulatory system. 4) the water we drink will be mostly absord by the blood vessels attached to the esophagus and stomach. Skip questionWhere are each of our macronutrients (carbohydrates, proteins and fats) chemically digested? Where does the process for each of them begin? Also note all locations in the GI tract that these processes continue (until each macronutrient has been broken down into components that our cells can absorb).
- The highest absorption efficiency for Vitamin E is __________________ and it must be solubilized as ______________________ in the intestinal lumen. 20%, chylomicrons 50%, chylomicrons 20%, micelles 50%, micellesWhat is the specific role of pepsin and pancreatin in protein digestion? Where can these enzymes be found in the body?Why are there so many mucin-producing glands along thelength of the GI tract?
- In upper gastrointestinal bleeding, without knowing the cause or source of bleeding, why do we give proton pump inhibitors (PPIS, e.g. omeprazole)? What is the role of these, if the source of bleeding is not peptic or duodenal ulcer?What are the major characteristics of the layers (mucosa, submucosa, muscularis externa and adventitia) in eachof the 4 major regions of the GI tract and what does that tell you about the function of each of those sections?Why does digestion need regulation and how is it achieved?
