  3. 3. Section 4-3<br />Multicelluar Organization<br />Most cells specialized to perform one or a few function<br />Due to specialization:<br />Cells of multicellular organisms depend on other cells in the organism<br />
  4. 4. Levels of Structural Organization<br />Atoms<br />Molecule<br />Organelle<br />Cell<br />Tissue<br />Organ<br />Organ System<br />Organism<br />
  5. 5. Tissues<br />Cells that are organized into groups that carry out a specific function<br />Examples:<br />Epithelial tissue – sheets of closely packed cells<br />Skin<br />Connective tissue – Loosely scattered cells<br />Muscle tissue – Cells that pull against each other<br />Nerve tissue – Cells that transmit signals<br />
  6. 6. Epithelial Tissue<br />

  12. 12. Organs<br />Several types of tissues that interact to perform a specific function<br />All organisms have organs except most simple<br />
  13. 13. Organ Systems<br />Groups of organs that work together to perform a set of related tasks(need each other)<br />Examples:<br />11 Systems in the Human Body<br />Cardiac<br />Nervous<br />Skeletal<br />Muscular<br />Digestive<br />Reproductive<br />Immune<br />Respiratory<br />Excretory<br />Endocrine<br />Lymphatic<br />
