• Name the levels of organization of the body from
  simplest to most complex, and explain each.


• Define the terms metabolism, metabolic rate, and
  homeostasis, and use examples to explain.

  works, and how a positive feedback mechanism
  differs.


• Describe the anatomic position.


• State the anatomic terms for the parts of the body.

  of body parts with respect to one another.


• Name the body cavities, their membranes, and
  some organs within each cavity.
