It's been a while since I took any so I don't have specific recommendations (offerings may have changed), but I've taken many good medical-related courses on both EdX and Coursera. I'd look at those first.
Khan Academy AP Bio and AP Chem would probably be helpful too for making sure you understand the basics.
You could also look into the ASU Universal Learner Courses-- pay the $25 registration fee but not take them for a grade. All the science courses I've taken through them are excellent.
I highly recommend NinjaNerd on YouTube for understanding things in more detail from a medical and anatomical perspective, but you need a good basis in bio and chem to really follow a lot of the lectures.
