# What is the function of buffers?

In the human body, certain buffers help maintain a consistent pH in order to keep enzymes running smoothly. These buffers achieve this task by taking away ${H}^{+}$ and adding $O {H}^{-}$ when the pH is too low (acidic), while adding ${H}^{+}$ and taking away $O {H}^{-}$ when the pH is too high (basic).
