Test Two
Show Answers:

  1. Three major components of blood
    • fluid
    • pumping organ
    • vessels
  2. Explain the fluid
    •                                                               i.      Blood (Hemolymph)
    • 1.      Used to carry all the materials need to carry all the materials that need to be transported
  3. Explain the pumping organ.
    1.      Some structure has to provide the pressure for the movement of the fluid through the system
  4. Explain the vessels.
    1.      Tubes (Conduits) that allow for transport from one part of the body to the next
  5. Function
    • a.      Transport
    •                                                               i.      Of nutrients, wastes, respiratory gases, hormones
    • b.      Maintenance of Body Fluids
    • c.       Temperature Regulation
  6. What are the types of life exhibited based on circulatory systems?
    • animals with no
    • animals with open
    • animals with closed single
    • animals with closed double
  7. Some animals who have a __ don't need a circulatory system. 
    What are tehy.
    have a simple structure or large SA

    • a.      All (or most) are aquatic and they have no need for a circulatory system
    •                                                               i.      Cnidaria (hydra)
    •                                                             ii.      Porifera (sponges)
    •                                                           iii.      Ctenophors
    •                                                           iv.      Playtehelminthes
    •                                                             v.      Nematoda
  8. All other animals have a circulatory system, whether __ r __.
    Open are found in...? Closed?
    invertebrate or vertebrate

    • a.      Open Circulatory System
    •                                                               i.      Found in invertebrates, arthropods and non-cephalopod mollusks
    • b.      Closed Circulatory System
    •                                                               i.      Found in rest of invertebrates (cephalopod mollusks, like squids), annelids, echinoderms (starfish), etc.
    •                                                             ii.      All vertebrates (fish, amphibian, birds, reptiles, mammals)
  9. Compare and contrast...between open and closed.
    • a.      Open: Hemolymph, open-ended pfluid, exchange between circulatory system and tissues of the body occurs in large cavities called hemocoels
    • b.      Closed: where vessels are continuous, the exchange between the circulatory system and the tissues occurs at capillaries
  10. Compare and contrast...between open and closed.
    •                                                               i.      Open
    • 1.      Arteries (transport material away from the heart)
    • a.      In open, the arteries end in hemocoel and the veins begin in a hemocoel
    • b.      The artery end is open and the vein beginning is open
    • 2.      Veins (transports blood toward the heart)
    • 3.      No capillaries
    •                                                             ii.      In closed, there are arteries, capillaries (site of exchange), and veins
  11. Compare and contrast...between open and closed.
    •                                                               i.      Fulid called Hemolymph drops off into body cavity in open circulatory system
    •                                                             ii.      Closed system contains blood
