rewatch submit

Explanation:

A buffer is a solution that resists changes in pH when small amounts of an acid or a base are added. It does not make the body more basic (unless a basic buffer is added in excess which is not the general function), nor does it change the pH (its role is to resist change). Its main function is to prevent changes in pH of our body (or any solution it is in).

Answer:

prevent changes in pH of our bodies
