Hi CJ, 
 
I hope you are doing well! Sorry for this late response, our advisors took a break for the holidays. 
 
Two science sources together is generally doable, however any more than that can get a bit tough. It looks like you would be taking Biochem and Anatomy, which are very different in terms of content. Anatomy is very memorization heavy, and though Biochem can be too, the exams are require more application-based knowledge. If the rest of your schedule isn’t too heavy, I would say you should be good to go. If the med schools you are interested in require anatomy in person, I would definitely take it in person. 
 
Physiology is different than anatomy in that it is focused on processes. I took animal physiology, and you focus on things like the respiratory system, kidneys, and digestion. Whereas in anatomy, you would learn the parts of these processes, but not necessarily go in depth into how they actually function. 
 
I hope this helps! If you have other questions, feel free to respond to this post or attend our advising hours.
