Peptic ulcers are sores in the lining of the stomach that are caused by a bacterial infection. these bacteria increase the acid in the stomach and eat away at the stomach lining, which causes sores. when this occurs, which type of tissue does the acid remove? a. connective b. epithelial c. muscle d. nervous

B. epithelial

Explanation:

The acid caused by the bacteria that cause peptic ulcers removes the epithelial tissue that lines the stomach.

Normally, the epithelial tissue of the stomach and small intestine are protected against irritating acids produced within the stomach. If the protective coating stops working properly, it results in an inflammation (gastritis) or an ulcer. Most of them occur in the first layer of the inner lining.

The most common cause of this injury is infection of the stomach by bacteria called Helicobacter pylori (H.pylori). Most people with peptic ulcers have these bacteria living in their gastrointestinal tracts, but it is not because someone has them present in their body that they will necessarily develop ulcers.
