Q

Gastritis is characterized by a disruption of the __ barrier that normally protects the stomach tissue from __ juices. The impaired mucosal barrier allows corrosive HCI, __, and other irritating agents to come in contact with the gastric mucosa, resulting in inflammation. In acute gastritis, this inflammation is usually transient and self-limiting in nature. In chronic gastritis persistent or repeated insults lead to chronic inflammatory changes and eventually __ of the gastric tissue

A

mucosal
digestive juices
pepsin
atrophy

Q

peptic ulcer disease mainly occurs in the gastroduodenal mucosa b/c this tissue cannot withstand the digestive action of gastric acid and pepsin. the erosion is caused by the increased concentration of acid-pepsin (HCI) or by decreased resistance of the mucosa. A damaged mucosa cannot secrete enough mucus to act as a barrier against HCI. The use of __ inhibits the secretion of mucus that protects the mucosa. Patients with duodenal ulcers secrete more acid than normal, whereas patients with gastric ulcers tend to secrete normal or decreased levels of acid. damage to the gastroduodenal mucosa results in decreased resistance to bacteria, and this infection from _ __ bacteria may occur.

NSAIDs

H. Pylori
