Questions to answer:

  1. Why is the presence or absence of vascular tissue a major evolutionary delineation for plants?  How does the presence/ absence of vasculature tissue constrain bryophyte anatomy?
  2. Explain how transpirational pull is created starting with the roots and ending with evaporation of water at the stomates.
  3. How is control of stomates utilized by different types of plants.
  4. Diagram the pressure flow hypothesis for phloem transport of sap.
  5. What are the trends that are seen in animal circulatory systems over evolutionary time?
  6. Compare the open circulatory system of arthropods with the closed circulatory systems of vertebrates.
  7. Explain how the components of blood allow for the various functions of blood.
  8. Compare arteries, capillaries and veins.
  9. Diagram the path that blood flows through the mammalian body.  Include all four chambers of the heart, and all arteries and veins that lead immediately to and from the heart.  Indicate where blood is the most oxygenated, and where it is the least oxygenated.
  10. Explain how heart beat is regulated in the mammalian heart, and how that heartbeat relates to blood pressure.
  11. Why do animals need specialized systems to exchange gasses with the environment?
  12. What are the characteristics of a functional respiratory surface?
  13. Diagram an alveolus to show blood flow, air flow, and oxygenation of both.
  14. Compare the transport of oxygen and carbon dioxide in the bloodstream.
