With a combination of text and graphics Precepts of Anatomy and Physiology will not only teach your older child about the interdependency of body systems bone, tissue and organs of the incredible human body. It will also delve into that awkward topic, reproduction. It is a judgment call, how much you teach and when but if your teens are ready for a more mature look at the origin of human life, this is the most age appropriate we have seen. All the nitty gritty details a teen needs to know, with the author's much appreciated bias as to the necessity of marriage as a prerequisite.
What the publisher recommends: "The Precepts of Anatomy and Physiology can serve as a stand-alone unit study worthy of 1/2 high school transcript credit in anatomy, or may be included as an adjunct to the Principles, Theories and Precepts of Biology course for 1 or 1 1/2 biology credits, depending on local or state policies for assigning transcript credit for high school courses."
