This book examines comprehensively all the major health topics covered in an introductory health course and may be used in courses with a science orientation as well as in those oriented toward behavioral and social issues. The book is designed so that each chapter is a complete, independent unit. Relevant physiological facts are presented in the first section of the chapter. At the end of each chapter is a summary, review questions, a glossary, and suggested readings. The overall organization of the book lends itself to a thematic approach. Early chapters--such as "Personality Development" and "Smoking and Health"--are concerned largely with the individual. Chapters in the middle of the book - such as "Human Sexuality" and "Marriage and Parenthood"--are concerned largely with human relationships. Later chapters, including "Nutrition" and Venereal Diseases" examine public health problems. The final chapter, "Environmental Health and Population", deals with matters of global significance. (DMT)
