A brief, to-the-point, easy to understand presentation of the most high-yield points in clinical physiology. Particular emphasis on cardio-pulmonary-renal physiology enables the reader to see the conceptual unification of these areas of physiology. The same enjoyable approach is applied as well to blood cells and blood coagulation, the immune system, neurophysiology, the digestive system and the endocrine system by showing them as a clear conceptual whole in only 132 pages! Excellent USMLE Board Review.
