I wish I would have bought this book earlier in my medical school career. Not only would it have helped for all the physiology sequences (cardiac, renal, etc) but it would have been helpful for histology, neuro,and endocrinology. The pictures are great and the explanations are uncomplicated. If you are a visual learner then I highly recommend this book. I am an endocrinology TA and have found it as a wonderful resource. I have the color atlas of immunology and have ordered the pathophysiology and pharmacolgy books by thieme as well.
