I am currently taking Anatomy and Physiology (as separate courses). They will be done December 20th. Should I wait for grades? Or submit now?

These are core courses. I am torn because having these grades IN (and with A's) can certainly help my application. However, submitting in January-- due to the 4 week-ish grade verification period for OTCAS will be cutting it close to many deadlines.

If you did well on all of your other prerequisites then I would submit your application now. If you are applying to any schools with rolling deadlines then this could be especially helpful. You could also email your schools and ask how heavily this could impact your application. My application took about three weeks to be verified so you would probably be cutting it pretty close. Just my opinion though :)
