vomit, nauseated
嘔 centers on the physical act of vomiting and the feeling of nausea that leads to it.
嘔 combines 口 (mouth) with 區, which likely contributes the sound and may relate to expelling or a container, suggesting vomiting from the mouth.
The mouth 口 on the left and the container-like 區 on the right: imagine a mouth emptying its contents like a tipped-over container.
For オウ, picture someone vomiting and making a loud 'Oww!' sound: Oww -> オウ, as they clutch their stomach.
