Zachary’s Story Essay

A. An ulcer starts by eroding the mucosa of the G.I. tract wall. What functions of digestion and/or reabsorption might be lost if this seam is no longer functional? What functions will be compromised if the ulcer consume through the sub mucosa and then the muscularis? Absorption would not hazard correctly some of the ingested and secreted may seep out of the lumen. This also could shape a pathway of entry for pathogens if the ulcer ate through to the muscularis mucosa. You may lose some control of defacation.B. If Zach has a peptic ulcer touch his ache or duodenum, which components of the peritoneum will be affected? If the ulcer take a hole into the wall of the stomach, bacteria and partially digested food rotter spill through h the opening into the peritoneum causing severe discharge of the abdominal cavity and wall.C. How can Zachs stomach contribute to the institution of ulcers in other parts of the G.I. tract? Which cells are direct participants in formation, and how do they contribute to lesions in the G.I. tract wall? Zachs stomach contributes to the formation of ulcers by the acids needed to breakdown food when they are excessive. parietal cells (secrete HCI) and gastric glands (acetylcholine) are directly related to the formation of ulcers.D. Why does Zachs G.I. tract need the substance that contributes to the formation of ulcers? How is this substance secreted by cells indoors the gastric pits? Zachs G.I. tract needs the substance to assist in the breakdown of food and for absorption. Epithelial cells extend into the lamina where they form secretory folds called gastric glands. Several of these glands open into the gastric pits and secretions from these glands flow into the pits.
