  1. agranular white cells: Lymphocytes and monocytes. Responsible for immunity.
  2. albumin: From the liver, helps maintain blood's osmotic pressure and volume.
  3. arterial blood: Lots of oxygen= bright red.
  4. components of plasma: Water, blood proteins, plasma proteins, nutrients, electrolytes, hormones, vitamins, enzymes, metabolic waste products.
  5. diapedesis: When white cells move through capillary wall into neighboring tissue.
  6. erythrocytes: Red blood cells. Shape= biconcave discs.
  7. erythropoiesis: Manufacture of red blood cells. Occurs in bone marrow. Red cells live 120 days. Old cells are broken down by the spleen and liver.
  8. fibronogen: Necessary for blood clotting, synthesized in the liver.
  9. function of hemoglobin: Red cells travel through the lungs where oxygen is carried to tissues and released CO2 is picked up and carried back to the lungs for exchange.
  10. granular white cells: Neutrophils, eosinophils, and basophils. Fight infection.
  11. hemoglobin: Gives red color; heme= iron, globin= protein. Function is to transport oxygen to tissues and CO2 away from cells. Normal= 14-18 g in men and 12-16 g in women.
  12. hemolysis: Rupture or bursting of erythrocute. Can be from a blood transfusion or disease.
  13. heparin: An anticoagulant produced by basophils.
  14. leukocyte facts: Larger than erythrocytes. Five types. Normal count= 3200-9800. Manufactured both in bone marrow and lymphatic tissue. Translucent, ameboid in shape. MAIN FUNCTION IS TO FIGHT INFECTION!
  15. leukocytes: White blood cells.
  16. phagocytosis: Process when white cells surround, engulf, and digest harmful bacteria.
  17. plasma: Liquid portion of the blood. Straw colored.
  18. plasma proteins: fibronogen, albumin, prothrombin.
  19. platelet facts: Smallest of solid blood components; synthesized in red marrow; not cells: they are fragments of megakaryocytes; necessary for the initiation of the blood clotting process; short life span (5-9 days); primary function is coagulation.
  20. prothrombin: A globulin that helps blood coagulate. Vitamin K is necessary for its synthesis.
  21. thrombocytes: Platelets.
  22. types of white cells: Neutrophils, eosinophils, basophils, lymphocytes, and monocytes.
  23. venous blood: Lots of CO2= dark crimson.
