Physiology Secrets, 2^nd Edition is a good balance of basic physiology and clinical applications with comprehensive coverage of physiology. As basic science courses are increasingly becoming problem-based, with an emphasis on clinical applications of basic science principles, the Secrets approach is ideally suited to present this kind of information. In its basic Q & A format, this approach is also especially well suited to focusing on the key information in each area of what can be a difficult subject of study.
