obviously i dont know what its like at your school, but at least for me, animal phys was more of a conceptual course more involved in the physics and commonalities of the design of physiological systems across animals. However, to keep it interesting we constantly came back to human phys and how the systems worked in people. My animal phys class covered ALL the physiology you'd find on the MCAT and more. Plus, I think the conceptual nature and comparing different animal systems made it easier to understand and more interesting that memorizing human phys.
just my experience, take it for what its worth
