This two-part unit study of anatomy and physiology introduces high school students to the wonders of the complex design of the human body. Thirty lessons discretely help students to understand the structure, function and interaction of body systems, organs, glands and hormones, as well as hazards to, and diseases of, various organs and systems. Content causes students to question whether life just happens, or whether it is the result of complex design and development. The course contains six quizzes and two chapter tests, plus answers. One of the objectives of this unit study is to equip teenagers with knowledge and principles to make positive life choices that will enhance health and happiness. Thus, students learn how life choices, diet, exercise, and even thoughts, affect physical and emotional health. The three final lessons of part two of Precepts of Anatomy and Physiology deal with male and female reproductive systems, discreetly worded and illustrated by line drawings. The student will learn that life begins at conception, and progresses through intricate and miraculous development of a baby from fertilization to birth. Students will marvel at the maturation process of bones, organs, tissues, muscles and joints that compose the wonders of the human body. Lessons are also applicable as supplemental material for sex education or abstinence studies. Precepts of Anatomy and Physiology is a popular course for students who want to know how they developed as humans, and how they are designed to reproduce life as males and females. This unit study is very popular with students who are considering medical careers and/or parenting. Precepts of Anatomy and Physiology is packaged in two chapters of soft-cover text and two companion activity books. It can serve as a stand-alone unit study worth ½ high school transcript credit in anatomy, or may incorporate chapters 2 and 3 from the Principles, Theories and Precepts of Biology course to create one high school transcript credit in Anatomy and Physiology (providing those chapters have not been counted for biology credit). Refer to local or state policies for assigning transcript credit for high school science courses.
