study of the structures in the body
anatomy
study of the processes of the body
physiology
structural and functional organization of the body
- Chemical level – atoms
- Cell level – molecules
- Tissue level – similar cells and surrounding materials
- Organ level – different tissues combine to form organs
- Organ system level – different organs work together
- Organism level – organ systems make up
the small structures that make up some cells
