I would say Biochem would be immensely helpful for the application. Having this foundation will not only be good for the MCAT (if you haven't taken it yet) but it is also helpful for other classes in medical school that will progress quickly. Additionally, this might be required or heavily recommended by several schools.
Human Phys and Anatomy could be helpful for the app, but those classes are generally several credits and as @baxt1412 said, you will learn them in medical school. Unless you want to take the time now to take these classes, I would say pass on this. If you wanted to decide between the two (if that's an option) I would go with physiology.
Micro might be helpful too, but not a make or break decision.
Personally, I only took Animal Physiology and Biochemistry out of these options and I have received one acceptance so far.
In sum, it is your decision. Just make sure you double check you have fulfilled all classes required/recommended by the schools you are interested in.
Don't forget about Genetics.
Best of luck.
