      Systole is the relaxation phase of the heart, and Diastole is the contraction phase of the heart.

    • B. 

      Systole is pumps the blood, Diastole fills the chambers with blood.

    • C. 

      Systole is the contraction phase of the heart, and Diastole is the relaxation phase of the heart.

    • D. 

      B and C

    • E.

      Plasma

    • B. 

      Endothelium

    • C. 

      Lymph Nodes

    • D.

    • E. 

      All of the above

  • 4. 
    What are red bloods cells produced by?
  • 5. 
    Mammals including humans use positive pressure breathing or negative pressure breathing?
  • 6. 
    When ph lowers, hemoglobin's affinity for O2 does what? (Also know as the Bohr Shift)
    • A. 

      It lowers

    • B. 

      It raises

    • C. 

      Allows more 02 for to be used for cellular respiration.

    • D. 

      A and C

    • E. 

      B and C

  • 7. 
    Countercurrent exchange is used in fish to  maximize oxygen absorption efficiency. What is the process it uses.
    • A. 

      Blood flows in the opposite direction of the water coming in. This way the blood at the end of the blood stream is constantly getting more 02.

    • B. 

      They have two separate vessel systems each going in different directions, this doubles the amount of blood and oxygen, because it is has a greater amount it can absorb.

  • 8.

    • A. 

      Low-density lipoproteins.

      High-density lipoproteins.

  • 10. 
    How do Myogenic and Neurogenic hearts differ? 
    • A. 

      The neurogenic heart doesn't separate the the oxygenated blood from non-oxygenated blood.

    • B. 

      The neurogenic hearts is controlled by stress factors and subconsciously by the body. Myogenic is controlled purely by the subconscious.

    • C. 

      Myogenic heart is found in most arthropods. Neurogenic is found in all vertebrates.

    • D. 

      Myogenic hearts are controlled from the inside muscle tissues. Neurogenic is controlled by the muscle tissues on the outside.

    • E. 

      Neurogenic hearts are more complex.
