"Animal Physiology is the acclaimed textbook by Knut Schmidt-Nielsen for all undergraduate and graduate courses in physiology. The book is used all over the world, and its comprehensive coverage and clear style are unparalleled." "NOw in its fifth edition, the textbook has been extensively updated to take into account recent developments in the field. Numerous new references and figures have been added, and the use of color to highlight illustrations and text guides the reader through each chapter." "Central to this popular textbook is its focus on the fundamental principles of animal physiology. As in the previous editions, these are introduced and developed according to major environmental features - oxygen, food and energy, temperature, and water. It covers the basic principles with greater clarity than its competitors and is the only textbook of its type to place function clearly in relation to environment." "With the user-friendly cohesion of a single-authored textbook, Animal Physiology is the essential core text for all those studying physiology or zoology."--Cover.
