Understanding Human Anatomy and Physiology encompasses three goals: to develop a working knowledge of (1) anatomy and physiology that is based on conceptual understanding rather than rote memory; (2) medical terminology that will increase the student’s con?dence in their chosen ?eld; and (3) clinical applications to broaden their horizons beyond the core principles. This edition follows the same general sequence as the earlier editions. It is divided into ?ve 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.
