This first seven lessons in this comprehensive eleven lesson unit introduce students to the anatomy and function of themajor organ systems of the human body: the skeletal, nervous, circulatory, respiratory, excretory, digestive, and muscular systems. Following their study of HUMAN BIOLOGY (PART A), students will be able to identify the major organs of each system and explain the functional role they play in that system as well as their importance to other systems. Students will construct a life-size chart of the human body that illustrates the anatomy of these integrated body systems. STUDENT WORKSHEETS and an EDUCATOR GUIDE are included in this download. The UNIT TEST for assessing student performance after completing HUMAN BIOLOGY (PART A and B) is included in HUMAN BIOLOGY (PART B).
