Question

why hcl is needed for our body

Answer 1

hcl creates acidic medium for action of an enzyme, pepsin.(protein digesting enzyme)

it also kills bacteria in the food.

Answer 2

HCl (Hydrochloric Acid) helps our body in digestion.

When the half churned food reaches the stomach, the proteins need to be digested.

When HCl is secreted, the pH of the stomach becomes 2-3, and so, the pepsinogen gets secreted which digests the protein.
