This updated, student-centric revision of Essentials of Anatomy& Physiology is written in a clear and concise manner to help students from all backgrounds prepare for a career in the allied health professions. The eighth edition simplifies the complexities of anatomy and physiology in ways that enhance understanding without diluting the essentials of the subject matter. The sequence of chapters and content within each chapter progresses from simple to complex. Chapters covering an organ system begin with anatomy to ensure students are well prepared to understand the physiology that follows. Each system chapter concludes with a brief consideration of common disorders the student may encounter in the clinical setting.
