they apply concepts associated with human anatomy and physiology. Studies will include the process of
homeostasis and the essentials of human function at the level of genes, cells, tissues, and organ systems. Students
are to understand the structure, organization, and function of the various components of the healthy human body
in order to apply this knowledge in all health-related fields.

Students enrolled in this course should have a basic understanding of the indicators in the following subsections of Standard 1, Principles of Biology (Biology 1, ISBE 2000): • Developmental and Organismal Biology Students should also know the principles of atomic structure, bonding, molecules, and structural formulas, types of
