- White blood count (WBC)
- Universal donor
- a percentage of total blood volume composed of red blood cells. Normocytes are normal sized, microcytes are smaller than normal, macrocytes are larger than normal
- b overabundance of red blood cells
- c type O-, although can be misleading and transfusion reaction is possible
- d total number of white blood cells in blood. Leukopenia is lower than normal, Leukocytosis is abnormally high WBC, Leukemia (cancer of red marrow) results in leukocytosis
- e thrombocytes, minute fragments of cells consisting of a small amount of cytoplasm surrounded by plasma membrane. Derived from megakaryocytes. Form platelet plugs, promote formation and contraction of clots. Have proteins and glycoproteins allowing them to attach to other molecules. Contain actin and myosin

5 True/False Questions
Differential white blood cell count → percentage of each of the five kinds of white blood cells in the WBC.
Red blood count (RBC) → total number of white blood cells in blood. Leukopenia is lower than normal, Leukocytosis is abnormally high WBC, Leukemia (cancer of red marrow) results in leukocytosis
Fibrinogen → made up of plasma, is 8% of the body weight. A type of connective tissue. Important component of the immune system
Hemolytic disease of the newborn (HDN) → also called erythroblastoisis fetalis: if mother produces exposed to a fetus who is Rh positive when she is negative, she will develop anti-Rh antibodies that cross the placenta and cause agglutination and hemolysis of fetal red blood cells.
Albumin → 58% of the plasma proteins. Important in regulation of water movement between tissues and blood. Maintains water balance.
