What is the most complex level of body organization?
Levels of structural organization in the human body work from simple to complex, or small to large. For instance, the simplest level, or “chemical level”, consists of atoms and molecules. The highest and most complex level of organization, the organismal level, represents the sum total of all structural levels working together in unison.
