The Medical Focus reading, “Dehydration and Water Intoxication” is also new to this edition. Chapter 4: Body Tissues and Membranes Each type of tissue now has its own major section. In addition to body membranes, connections between cells and different types of glands are discussed in respective sections. Art and ta￾bles have been revised for this chapter. Chapter 5: The Integumentary System Section 5.5. Homeostasis is new to this edition. It shows how the various functions of the skin assist the body in maintain￾ing homeostasis. Also discussed are hyperthermia and hy￾pothermia, which occur when homeostasis has been over￾come. The section is accompanied by an updated Human Systems Work Together illustration. Chapter 6: The Skeletal System New illustrations, each of which is on the same or a facing page to its reference, much improve this chapter. More infor￾mation is given about each bone and joint discussed. The chapter ends with a review of the many ways the skeletal sys￾tem helps maintain homeostasis. Chapter 7: The Muscular System The first two illustrations in this chapter are new: The first shows the three types of muscles, and the second describes the connective tissue coverings within and around a skeletal mus￾cle. Instructors and students will appreciate the new in-depth discussion of the sources of energy for muscle contraction, which is also accompanied by a new illustration. Chapter 8: The Nervous System This chapter was rewritten. In particular, the discussion of the cerebrum has been expanded to include not only the various lobes but also the areas within these lobes. The somatic sys￾tem of the peripheral nervous system is now clearly defined, and the spinal reflex has been moved to this section. New il￾lustrations support improved discussions of all aspects of the nervous system. Chapter 9: The Sensory System Types of senses, rather than types of receptors, are now used to organize this chapter. The discussions of the anatomy and physiology of the eye and ear are better organized, with an em￾phasis on how information regarding vision and sound is gen￾erated and transmitted to the brain. The sense of equilibrium is now divided into rotational and gravitational equilibrium. Chapter 10: The Endocrine System An overview of the endocrine glands now precedes an im￾proved discussion of each gland. A new illustration shows how the adrenal medulla and the adrenal cortex are in￾volved in short-term and long-term stress, respectively. Other new illustrations pertain to regulation of blood cal￾cium, regulation of blood pressure, Addison disease, and Cushing syndrome. The chapter also includes a discussion of chemical signals in general and how hormones affect cel￾lular metabolism. Chapter 11: Blood A detailed description of the composition and function of blood now opens the chapter. There follows a more compre￾hensive look at the formed elements. The section on platelets centers around hemostasis, including coagulation. The trans￾port function of blood is illustrated by considering capillary exchange. The last section of the chapter, Blood Typing and Transfusions, is supported by new art that clearly illustrates blood types and agglutination. Chapter 12: The Cardiovascular System An overview of the cardiovascular system, supported by an illustration, offers a much-improved introduction to the chapter, which has been reorganized into five parts: the anatomy of the heart, the physiology of the heart, the anatomy of blood vessels, the physiology of circulation, and circulatory routes. A better discussion of cardiac output and peripheral resistance improves the presentation of the chapter. Chapter 13: The Lymphatic System and Body Defenses As requested by reviewers, the lymphatic organs are now divided into those that are primary and those that are sec￾ondary. The discussion of specific immunity is much im￾proved by new illustrations depicting the action of B cells and T cells. A new reading on emerging diseases modernizes the chapter. Chapter 14: The Respiratory System An improved Table 14.1, which includes a description of the respiratory organs, adds to the discussion of the respiratory system. The respiratory membrane is better described and is accompanied by a new illustration. The section entitled Mechanism of Breathing is better organized so that regulation of breathing rates now has its own subsection. Following reviewers’ suggestions, the chapter is more student friendly because gas exchange and transport no longer require a knowledge of partial pressures. All readings are new or exten￾sively revised. x Preface
