Abstract

Gain a foundational understanding of renal physiology and how the renal system functions in health and disease. Renal Physiology, a volume in the Mosby Physiology Series, explains the fundamentals of this complex subject in a clear and concise manner, while helping you bridge the gap between normal kidney function and disease with pathophysiology content throughout the book.

  • Helps you easily master the material in a systems-based curriculum with learning objectives, "In the Clinic" and "At the Molecular Level" boxes, chapter summaries, clinical cases with review questions and answers, self-study questions, and a comprehensive exam.
  • Includes more than 250 clear, 2-color diagrams that simplify complex concepts.
  • Features clinical commentaries that show you how to apply what you've learned to real-life clinical situations.

Complete the Mosby Physiology Series! Systems-based and portable, these titles are ideal for integrated programs.
