Where to take online classes?

I am looking to take two courses online, which I need to do before the Spring 2014 semester. These courses are Human Anatomy and Human Physiology (and both must be worth 4 credits and include a lab). I realize that usually Human Anatomy and Physiology is offered as one course, but because of my timeline, I can either take A&P I and II before the spring, or Anatomy as one course and Physiology as another. The latter is more likely. Please let me know of any schools which may offer these courses. Thank you. I have found the UNE does offer them in a desirable format-you can sign up at any time and the courses are self paced, but they are a little costly.
