Microscopic Anatomy: examines cells and molecules. O Cytology: study of cells. O Histology: study of tissues. Physiology: is the study of functions of anatomical structures. *Smallest living is a CELL. *Smallest organismsis a ATOM. Levels of Hierarchy Atom- the most basic complete unit of an element.
