    a. 5,000 - 10,000 per cubic millimeter of blood
    2. Leukopenia
    a. Low WBC count (below 5,000)
    3. Leukocytosis
    a. High WBC count (above 10,000)

  5. 1. Protect body against microorganisms and remove dead cells and debris, infection. Can level the blood vessels. work like an ameoba.
    2. Diapedesis: cells become thin, elongate and move either between or through endothelial cells of capillaries
    3. Chemotaxis: attraction (chemical) to and movement toward foreign materials or damaged cells. Accumulation of dead white cells and bacteria is pus.

5 True/False questions

  1. Coagulation (Clotting)clumping of red blood cells in response to a reaction between an antibody and an antigen

          

  2. reason for high hematocrit1. lack RBCs
    2. too much water

          

  3. Thrombocytopeniatoo many platelets (too much clotting)

          

  4. Formation of WBC1. Stimulated by colony stimulating factor
    2. ones that die signal to make new ones
    3. interleukin = cause WBC formation

          

  5. Blood Clot1. A network of threadlike fibrin fibers, trapped blood cells, platelets and fluid
    2. Clot retraction. Fibrin threads of clot attached to blood vessel walls.
    a. Platelets produce processes that attach to fibrin threads.
    b. Actin and myosin molecules within platelets contract, pulling edges of wound together and squeezing out serum.
