The root 'os' refers to which anatomical part?

Explanation:
The root os carries the meaning of the mouth. In medical terms, os comes from Latin for mouth (often seen as oris in related forms), and it shows up in words tied to the mouth or mouth-related openings, like oral or orifice. That’s why this root points to the mouth, not the ear (which uses roots like oto- or aur-), not oxygen (oxy-), and not egg (ovo-). So the anatomical part indicated by os is the mouth.
