Moore Clinically Oriented Anatomy and Guyton Physiology, however, I think most books will be overkill for EMT. My EMT class I think spent 4 hours on anatomy? Whatever book your EMT class is going to use, it probably has a chapter on anatomy and physiology, and that's probably what I would focus on to pass the class. The anatomy and physiology EMTs learn isn't very comprehensive. Most Anatomy and Physiology books will probably take longer to read than to complete the EMT class. You'll likely take one test on it early on, some questions will pop up in your final, and then some questions will pop up in the NREMT. I think it'll be low yield. There likely won't be a lot of questions on it in your final or on the NREMT. People say that knowing your anatomy and physiology will help make you a good clinician, but I personally think it won't help a lot to pass the class or NREMT unfortunately.
