Hehe, well, they do teach the basics in undergrad, depending on your major. For a while, I thought they were the same class. But anatomy is basically straight up memorizing whats in the body, learning the names of every single vessel, nerve, muscle, bone, organ in the body, plus what supplies what, what innervates what, etc.
Physio is a much more interesting class in my view. That actually explains how everythign works, the mechanisms our body uses to get through. The main physio topics at my school are Cardio, Respiratory, Renal, GI, and Endocrine.
