  2. Structural Organization • Cells • Smallest, most numerous structural unit • Tissues • Groups of similar cells with specialized functions

  3. Structural Organization • Organs • Tissues arranged together to perform a particular function • Body systems • Organization of different organs to perform bodily functions

  4. Terms Relating to Cells • Anaplasia • Aplasia • Dysplasia • Hyperplasia • Hypoplasia • Neoplasia
