New Design and Illustrations A new, colorful design and revised illustrations enhance the features of Understanding Human Anatomy and Physiology, fifth edition. Organization This edition follows the same general sequence as the earlier editions. It is divided into five parts: Part I, “Human Organization,” provides an understanding of how the body is organized and the terminology used to refer to various body parts and their locations. Chapters 2 through 4 describe the chemistry of the cell, cell structure and function, and the tissues and membranes of the body. Part II, “Support, Movement, and Protection,” includes the integumentary system in addition to the skeletal and muscular systems. Part III, “Integration and Coordination,” explains that the nervous and endocrine systems are vitally important to the coordination of body systems, and therefore homeostasis, while the sensory system provides the nervous system with information about the internal and external environments. Part IV, “Maintenance of the Body,” describes how the cardiovascular, lymphatic, respiratory, digestive, and urinary systems contribute to the maintenance of homeostasis. Part V, “Reproduction and Development,” concerns the reproductive systems, development, and the basics of human genetics, including modern advances. Homeostasis The theme of homeostasis is strengthened in this edition. As before, Chapter 1 describes how various feedback mecha￾nisms work to maintain the internal environment within a narrow range. New to this edition, each systems chapter ends with a major section on homeostasis to accompany the “Hu￾man Systems Work Together” illustration. This section de￾scribes how the system under discussion, with the help of the other systems, maintains homeostasis. New Readings Understanding Human Anatomy and Physiology, fifth edition, has two types of readings. Previously, the book had two types of readings called Medical Focus and MedAlert. In this edition, the readings are Medical Focus and What’s New. Some of the Medical Focus readings from the fourth edition have been re￾moved, and most of the others have been revised. The What’s New readings, which are new to this edition, tell of treatments that are now experimental but promise to be particularly help￾ful in the future. For example, a What’s New box in the first chapter tells about organs made in the laboratory that are now being transplanted into patients. The What’s New reading in Chapter 8 describes a “pacemaker” for Parkinson disease. Chapter Openers Scanning electron micrographs, X-rays, and MRI images open the chapters for a closer look into the wonders of the human body. The integrated outline has been retained with the addi￾tion of a numbering system for each major concept found in the chapter, including the summary. Visual Focus Visual Focus illustrations are included in several chapters. With the addition of boxed statements, these in-depth illustra￾tions, which contain several art pieces, cover a process from start to finish. For example, Figure 7.3 outlines contraction of a muscle from the macroscopic to the microscopic perspective. Chapter End Matter This edition includes updated Selected New Terms, Sum￾maries, Study Questions, Objective Questions, Medical Ter￾minology Reinforcement Exercises, and Website Links to the Online Learning Center. Objective Questions Labeling exercises have been added to chapters 8, 11, 14, and 18 to reinforce the concepts of the chapter. Chapter Updates and Additions Chapter 1: Organization of the Body New illustrations, tables, and a reading titled “Organs for Transplant” introduce the student to the human body. The discussion of negative feedback now includes temperature control as an example and also includes a discussion of posi￾tive feedback, as requested by reviewers. Chapter 2: Chemistry of Life This chapter has been reorganized and rewritten to help stu￾dents understand fundamental chemistry concepts. Carbohy￾drates, lipids, proteins, and nucleic acids each have their own major section. Chapter 3: Cell Structure and Function Cellular Organization, Crossing the Plasma Membrane, and The Cell Cycle are clearly defined as chapter sections. Tables
