Objective(s):After this unit, student should be able to:

  1. Describe anatomy of blood
    1. Plasma
      1. water:  thermal, cohesive, solvent, also osmosis
      2. electrolytes (inorganic:  Na, K, salts (anions & cations)
      3. buffer: molecules that can accept of donate H+ ions (donate to bases and accept from acids to keep pH stable) 
      4.  
    2. Cells
      1. erythrocytes
      2. leukocytes
    3. Platelets
      1. thrombocytes
  2. Describe function of blood
    1. Describe role of oxygen, carbon dioxide and glucose in organisms in general terms
    2. Based on location (ie. muscle/intestine/lung/brain), explain whether oxygen/carbon dioxide/glucose are moving from tissue into blood or vice versa.
    3. Explain purpose of blood
      1. including molecules dissolved in the blood and their function
      2. cells in the blood and their function

(1) special features of erythrocyte shape
