Which acid destroys the bacteria that enter the stomach?
Answer & explanation
Correct answer: option 2
- Hydrochloric acid (HCl) is the acid present in the stomach that helps destroy the bacteria and other pathogens that enter the digestive system.
- The acidic environment of the stomach, with a pH of around 1.5 to 3.5, is highly effective in killing most of the bacteria and microbes that enter the body through food and drink.
- This strong acidity is essential for proper digestion and also acts as a defense mechanism, protecting the body from harmful pathogens that might be present in ingested food.
