Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Hydrochloric acid is a chemical that can burn your skin-and yet it exists in your stomach. How can this be?
A
Your small intestines absorb all the hydrochloric acid
B
The food in your stomach absorbs all the acid
C
Your stomach lining protects you against burns
D
The hydrochloric acid in your stomach is different from the hydrochloric acid you would find in a chemistry lab
Explanation: 

Detailed explanation-1: -Cells in your stomach called parietal cells produce this acid and secrete it into your stomach to help break down food. Even though hydrochloric acid can cause severe burns to your skin, your stomach is protected by a protective mucus layer produced by the cells that line your stomach.

Detailed explanation-2: -If the chemical is on the skin or in the eyes, flush with lots of water for at least 15 minutes. If the chemical was swallowed, immediately give the person water or milk, unless instructed otherwise by a health care provider.

Detailed explanation-3: -Your stomach protects itself from being digested by its own enzymes, or burnt by the corrosive hydrochloric acid, by secreting sticky, neutralising mucus that clings to the stomach walls. If this layer becomes damaged in any way it can result in painful and unpleasant stomach ulcers.
