Question

Linda has heard that the acidic environment of the stomach is similar to that of a car battery. if the stomach is so acidic, why doesn't the acid eat away at the stomach lining and cause holes in the stomach? the stomach contracts during peristalsis, which pushes the acid out of the stomach and protects it. the stomach produces bacteria, which denature the acid in the stomach and protect it. the stomach is lined with a layer of mucus that protects it. the stomach produces bicarbonate, which neutralizes the acid in the stomach and protects it.

Answer 1

there is a lining kind of like when you look at the nucleus <3

Step-by-step explanation:

i was thinking this for myself and basically have a process of elimination- sorry if it didn't help

Answer 2

The correct answer is "the stomach is lined with a layer of mucus that protects it".

The stomach is lined by a mucus layer resistant to acid degradation and this is facilitated by the production of protective prostaglandins in the stomach.

The stomach does not physiologically push acid out to during peristalsis as this can be a pathologic process that can cause damage to the esophagus and cause Barrett's esophagus and eventually adenocarcinoma. The stomach does not produce any bacteria and bicarbonate.
