1. ACOS 3
Relate major tissues and organs of the skeletal, circulatory, reproductive, muscular, respiratory, nervous, and digestive systems to their functions.
Arranging in order the organizational levels of the human body from the cell through organ systems

2. Levels of Organization
Cell-the smallest unit that is capable of performing life functions.
Tissue-a collection of cell working together to perform a job
Organ-a collection of tissue working together to perform a job
Organ System-a collection of organs working together to perform a job
Organism-a collection of organ systems working together to perform a job
