Agreed.  Also, glad to see "vulva" used.  It's what everyone sees on the outside.  "Vagina" is the most common term people use for the set of features visible from the outside, but it's incorrect... "vulva" is the correct term.  


Vagina is for lack of better term the hole within the vulva.

Anatomically, vagina is the "hole", but enough people have been using the term vagina to describe the entire thing, and English is a growing language, so I would not say it's wrong to describe it all as a vagina. Languages grow and change.
