This book provides readers with an anaesthesia-focused alternative to general physiology textbooks. The new edition has been reorganised with the trainee anaesthesist in mind, into shorter bite-sized chapters ideal for exam revision.  The content includes the physiology of all major organ systems, with specific emphasis on the nervous, respiratory, and cardiovascular systems as well as special sections on pain, aging, specific environments and obesity.  Alongside the learning objectives, reflection points and a handy summary of physiological equations and tables, there is greater emphasis on clinical application in this fourth edition, with applied physiology included in almost every section.
