  1. In the Beginning!!!!!!!!

  2. Physiology: Study of the function of the body. How everything works. Systems

  3. Anatomy: The study of the structures and parts of the body.

  4. Levels of Organization • Life can be broken down into physical and chemical levels. We will discuss seven different levels.

  5. ATOMS • ATOMS  • Atoms are considered part of the chemical level. (e.g. C, H, O, N)

  6. MOLECULES •  MOLECULES  • One or more atoms. Also known as the chemical level. (e.g. H20 CO2)

  7. CELL •  CELL  • The smallest living unit in the human body (e.g. cyto-, -cyte)

  8. TISSUE •  TISSUE  • A collection of cells that perform a specific function. • (e.g. muscle)

  9. ORGAN •  ORGAN  • Combination of tissues that perform complex functions. (e.g. heart, liver)

  10. SYSTEMS •  SYSTEM  • A group of organs that work together to perform one or more functions. (e.g. Nervous system, digestive)

  11. ORGANISM •  ORGANISM  • Human being. All systems work together. • (e.g. ME!)

  12. Review • Atom  Molecule  • Cell  Tissue  • Organ  System  • Organism

  13. Don’t forget • This flowchart can go both ways so add  arrows going backwards.

  14. Systems (WORK TIME) • Let us learn about systems of the body. Complete page 4 in you lab books. (Text pages 7-13)
