plasma correct answers ~55% of blood, mostly water, contains proteins and other dissolved
solutes like urea, salts, and organic nutrients
buffy coat correct answers white blood cells and platelets
formed elements correct answers red blood cells, white blood cells, platelets, fragments that
break off from larger cells
white blood cells / leukocytes correct answers help initiate immune responses and defend the
body against pathogens, motile and flexible, large, found in body tissues not bloodstream
- Never Let Monkeys Eat Bananas = neutrophils, lymphocytes, monocytes, eosinophils,
basophils
red blood cells / erythrocytes correct answers biconcave shape, most abundant blood cell, no
nucleus
platelets / thrombocytes correct answers one of the formed elements in the blood that is
responsible for aiding in the clotting process, no nucleus
granulocytes correct answers contain many dark staining granules in the cytoplasm of the cell,
multi-lobed nucleus; neutrophils, eosinophils, basophils
neutrophils correct answers nucleus has several lobes that look like beads on a string, and many
dark staining granules, usually about 60% of WBC
eosinophils correct answers nucleus forms two lobes and many pink staining granules, about 3%
of WBC
Basophils correct answers lobed nucleus hidden by many dark staining granules, usually <1% of
WBC
agranulocytes correct answers contain very few dark staining granules in the cytoplasm of the
cell; lymphocytes and monocytes
lymphocytes correct answers B, T, and natural killer cells, have an oval, evenly stained nucleus
that makes the cell look like a fried egg, about 25% of WBC
monocytes correct answers agranular leukocytes, bean shaped nucleus, about 10% of WBCs
sickle cell anemia correct answers a genetic disorder that causes abnormal hemoglobin, resulting
in some red blood cells assuming an abnormal sickle shape, slows blood flow and thus oxygen
delivery
, polycythemia correct answers elevated proportion of RBCs either via increase in RBC count or
decrease in blood plasma volume, can cause high blood pressure and clotting
infectious mononucleosis correct answers caused by Epstein-Barr virus, abnormally large
lymphocytes with wrong shape nuclei, "cytoplasmic skirting" around RBCs
leukemia correct answers unregulated overproduction of immature leukocytes
Which of the following blood diseases can be recognized by reactive lymphocytes characterized
by bright blue cytoplasm and "skirting" of red blood cells?
a. sickle cell anemia
b. polycythemia
c. infectious mononucleosis
d. leukemia correct answers c. infectious mononucleosis
hemagglutination correct answers clumping reactions involving red blood cells
type A blood correct answers erythrocytes with type A surface antigens and plasma with anti-B
antibodies, shows clumping with anti-A serum
type B blood correct answers erythrocytes with type B surface antigens and plasma with anti-A
antibodies, shows clumping with anti-B serum
type AB blood correct answers erythrocytes with both A and B antigens on the surface and
plasma with neither anti-A nor anti-B antibodies, shows clumping with both anti-A and anti-B
serum
type O blood correct answers erythrocytes with neither A or B antigens on the surface and
plasma with both anti-A and anti-B antibodies, doesn't show clumping with either serum
rhesus (Rh) factor correct answers + or -, positive can receive both positive and negative blood, -
can only receive - blood, will clump with anti-D if positive
If a patient who is type B+ blood receives a transfusion of type A+ blood, what would cause
agglutination of patient's blood?
a. reaction of anti-A antibodies in patient's blood with antigen A on surface of donor erythrocyte
b. reaction of anti-B antibodies in patient blood with antigen B on surface of donor erythrocytes
c. lack of antibodies in patient's blood
d. reaction of anti-A and anti-B antibodies in patient's blood with antigen A on surface of donor
erythrocytes correct answers a. reaction of anti-A antibodies in patient blood with antigen A on
surface of donor erythrocytes
