And a multitude of other 'jobs' you can get with a physiology major, some of which have absolutely nothing to do with the health sciences. That's a very broad question really...
This is a really important point, many students from VCE don't really understand the different between Health Sciences (or Human Sciences) and Biomedical Sciences.
what is the difference ??
Biomedicical science is anything to do with biology and medicine.
Health Sciences are those which particularly deal with only one species in great depth; that is, Humans, as this is undoubtedly a very important part of general Biomedical Science.
Studying Animal Physiology will give you broad, sweeping views of Animals as a whole given that it's more of a biomedical science subject. Studying Human Physiology will give you much more depth than the physiology that you would study in AP, but it won't be nearly as diverse, given that you generally need to know more about humans specific functions rather than the finnicky details of snail respiratory systems, for example.
And what a terrible example it was, but you catch my drift
Offtopic: I fucking love not having 2 of my normally 3 weekly pracs on the first week back. But I have so much bloody work to do and all I do is surf AN.
