The acid present in the stomach is hydrochloric acid (HCl). Its main function is to kill harmful bacteria that may enter along with the food. This is important because the stomach is the first line of defense against harmful pathogens that can cause infections and diseases.
Kills harmful bacteria
When we eat food, it passes through the esophagus and enters the stomach. The acidic environment of the stomach, with a pH of around 1.5 to 3.5, helps to kill most of the bacteria that may be present in the food. This is an important function of the stomach because it helps to prevent infections and diseases that can be caused by harmful bacteria.
Protects stomach lining
The acid in the stomach also helps to protect the stomach lining from being damaged by harmful substances that may be present in the food we eat. The stomach lining is made up of a layer of mucus that helps to protect it from the acid. The acid helps to break down the food we eat, making it easier to digest.
Does not digest starch
Contrary to the given answer option, the acid in the stomach does not digest starch into simpler sugars. The digestion of starch begins in the mouth, where it is broken down into simpler sugars by the enzyme amylase present in the saliva.
Does not make medium alkaline
The acid in the stomach makes the medium acidic, not alkaline. The acidic environment of the stomach is created by the secretion of hydrochloric acid by the cells lining the stomach.
In conclusion, the acid present in the stomach plays an important role in protecting the body from harmful bacteria that may be present in the food we eat. It also helps to break down the food we eat, making it easier to digest.
