Any general biosciences course will probably have some scope for various aspects of human biology and pathology. You will probably also have to study general mammalian and plant biology, and some ecological and evolution based topics on a general scale.
Biomedsci is just a specific subset of biosci. Generally if you're interested in human biology and medicine, a general biosciences course will end up having too much unrelated stuff (like I think most require at least 1 course in ecology in the US, although I don't know if this is an accreditation thing or just a common theme).
You'll probably end up doing more chemistry, biochemistry and molecular biology in a biomedsci course (possibly specifically revolving around human biology and medicine bu not necessarily) whereas these would probably be somewhat more ancillary topics in a general biosciences course.
Consider why you're interested in any courses in the biological regime in the first place, and you'll probably find your answer quite quickly.
