  1. WHat do all cells need?
    • a.      All cells need to respire; they need to take in oxygen, utilize it, and releases CO2 as a byproduct
    • b.      Without this, cells will die
  2. Three types of respiration?
    •                                                               i.      External: movement of O2 and CO2 in and out of the respiratory organs
    •                                                             ii.      Internal: occurs at capillary beds; movement of respiratory gases between the circulatory system and the tissues of the body
    • 1.      Exchange between cells and circulatory system
    •                                                           iii.      Cellular: utilization of oxygen and production of CO2 with glucose metabolism
  3. Adapatations
    • no respirartory system
    • tracheal system
    • gills
    • lungs
  4. No respiration
    • a.      Some don’t have a need for a respiratory system and do respiration at the level of their body surface
    •                                                               i.      High ratio of surface volume
    •                                                             ii.      No need for a circulatory system
    • 1.      Ex: aquatic invertebrates, annelids, some arthropods, very few vertebrates
  5. Tracheal System and examples
    •                                                               i.      Ex: insects and some arthropods
    •                                                             ii.      Unique in that it does not use the cardiovascular system for transport of the respiratory gases
    •                                                           iii.      Network of tubese
    •                                                           iv.      Only type of system that doesn’t utilize some form of transport
  6. Gill ex.
    in aquatic both vertebrates and invertebrates
  7. Lungs
    both vertebrates and invertebrates terrestrial
  8. The tracheal system is in?
    insects and arthropods
  9. What does the tracheal system not use?
    a.      DOES NOT USE CIRCULATORY SYSTEM TO TRANSPORT THE RESPIRTORY GASES
  10. What is the tracheal system?
    • a.      It is a network of tubes called tracheal tubes that are found throughout the organism’s body
    •                                                               i.      Respiratory gasses get in through an opening on the outside of the body called spiracles that tallow access into the tracheal tubes
  11. a.      The larger tracheal tubes are kept open through a larger tissue embedded in their walls called __made of __
    • tennidiae
    • cutin
  12. What are tennidiae?
    •                                                               i.      They are circular, hardened tissue (cutin) embedded in the walls of the tracheal tubes
    •                                                             ii.      The only place you don’t find them is in the tiniest tubes called tracheoles, but all the rest of the system does
  13. Function of tennidiae?
    •                                                               i.      Function: prevent collapse because they are the passageway of CO2 and O2 through system
    •                                                             ii.      Branch through all tissues of the body
  14. This muscle is every cell of the insect's body. 
    Where does it go?
    Gases?
    Circulation?
    Networks?
    • 1.      Goes to all tissues and at end of division, the smallest tracheoles allow exchange wbetween the tracheole and whatever tissue or cell is there
    • 2.      Oxygen is high in the tracheole tubes; CO2 is high in the tissues and so COmoves out               
    • 3.      No circulation
    • 4.      Networks throughout the body are tubes
