I checked around and it says here about the usage of 胃, however, I didn't see
おなか there.

What is the difference in おなか and 胃, in pronunciation and usage?

question
words kanji
Is there a difference with 胃 and おなか?
Both means _stomach_ , but おなか or 腹【はら】 refers to the whole _abdomen_ , while
胃【い】 specifically refers to [this organ](http://en.wikipedia.org/wiki/Stomach)
between the esophagus and the duodenum.
