You need to have Microbiology with Lab, Anatomy with Lab, and Human Physiology with Lab. At my school Anatomy, Anatomy Lab, Human Phys, and Human Phys Lab were 4 separate courses which were each taken in two sequential terms (i.e. Anatomy Lecture I and Anatomy Lab I followed by Anatomy Lecture II and Anatomy Lab II the next term). What I believe is meant by combined courses are obviously courses that combine Anatomy and Phys. A single class (taken in one term/semester) combining the two does not count, however, if the combined course has two sequential terms/semeters (i.e. Anatomy & Phys I followed by Anatomy & Phys II) then the combined courses are fine. I believe this is what it means, but to make sure you should call Pacific admissions, they are very nice and helpful.
