Compare the structure and function of the human body system to a nonliving system and how are they alike.

The human body is composed of interactive systems. Most organs in the body are necessary, a few like tonsils are not.  There are specific functions for each of the organs in the systems, but they cannot operate by themselves.
Below is a chart that will help you review the different systems with your students.
