The three major concepts developed in this unit are: the human organism's digestive and respiratory systems exchange energy and matter with the environment the human organism's excretory system exchanges energy and matter with the environment the human organism's circulatory system transports energy and matter to maintain equilibrium among the body systems as well as between the organism and its external environment.
