Yes the vagina is TECHNICALLY the fleshy entrance/exit to your uterus. I just find it increasingly annoying when I see people get bitterly offended when someone refers to the collective genitalia as a vagina. It's no different than someone calling male genitalia a penis. In all technicality you should refer to the specific parts of it such as the glans, the scrotum, etc yet all you ever hear is penis and testicles. You will never hear someone talk about how they kicked a guy in the scrotum. Long story short, STOP GETTING SO DAMN OFFENDED. Calling the whole area a "vagina" is much easier than specifying inner labia, clitoris, etc. For example if you are talking about "shaving a vagina." OBVIOUSLY you aren't talking about the canal, you are just talking about that region. The only time it should matter is if you are trying to be very very specific.
