CASE FILES: PHYSIOLOGY (Black & White), 2nd Edition by Eugene C. Toy is a case-based learning and review book designed to help medical students and health science learners develop a strong clinical understanding of physiology. It is especially useful for integrated learning and USMLE-style exam preparation.

The book presents core physiology concepts through realistic clinical cases, each followed by guided questions, detailed explanations, and key learning points. Major systems covered include cardiovascular, respiratory, renal, gastrointestinal, endocrine, neurophysiology, and acid–base physiology, with emphasis on mechanisms underlying clinical signs and symptoms.

A key strength of this book is its problem-oriented, case-based format, which helps students apply physiological principles to patient scenarios and strengthens clinical reasoning. Each case concludes with clinical pearls and review questions to reinforce high-yield concepts.

The language is clear, concise, and student-friendly, making it ideal for active learning, small-group discussion, and rapid revision. The black-and-white format keeps the focus on content and exam-relevant material.

Case Files: Physiology is highly recommended for students seeking a clinically integrated, high-yield, and exam-focused approach to mastering physiology.
