I'm looking for a light Knowledge base describing human body to annotate disease sites. I do not need a great level of detail, I just need kind of like basic organs/sub-organs taxonomy. I checked out the Foundational Model of Anatomy ontology, but it's over-killing for my purpose and really cumbersome (Protege fails while tries to load FMA.owl).

Is there a simple knowlege base available over the Internet?

(I'm new to this community, hope my question is not ill posed or completely OT)
