|
agglutinogens |
genetically determined antigens on the surface of every individual's erythrocyte |
|
|
agglutinins |
antibodies that bind to the antigens(agglutinogens) |
|
|
agglutination |
anitgen-antibody reaction which causes the red blood cells to clump together |
|
|
hematocrit |
the percentage of the total blood volume that is comprised of the packed red cells |
|
|
normal ranges for hematocrit |
adult males: 40-50% adult females: 36-45% |
|
|
how to test for blood type |
get a drop of blood in 3 separate areas mix with antibody A,B, and RH. when they clot with one of these that mean it has the agglutinogen. |
|
|
test for hematocrit |
fill a capillary tube with blood the put clay in one end put in centrifuge with clay facing out. measure total mm of liquid, then total mm of red |
|
|
hematocrit equation |
(red cell column/total blood column)x100= hematocrit% |
|
|
leukocytes |
white blood cells |
|
|
granulocytes |
cells containing cytoplasmic granules |
|
|
agranulocytes |
cells without cytoplasmic granules |

|
|
normal range of eosinophils |
2-4% |

|
normal range of basophils |
0.5-1% |
|
|
trabeculae of the spleen |
inward extensions of the capsule, thich chords |
|
|
capsule of the spleen |
outside layer of the spleen |
|
|
red pulp |
vascular tissue and forms the majority of the spleen |
|
|
white pulp |
lymphatic tissue and the purple dots within it are the darkly stained nuclei of lymphoid tissue |
|
|
fibrous capsule |
encloses the lymph node and extension of trabeculae |
|
|
trabechulae |
divides the lymph node into small compartments |
|
|
stroma of the lymph node |
supports cellular components formed by a network of reticular fibers |
|
|
reticular fibers of the lymphnode |
thick chords that extend from trabechulae |
|
|
cortex of the lymph nodes |
outer region of the lymph node |
|
|
medulla |
inner region of the lymph node |
|
|
medullary chords of the lymph nodes |
chords of dense areas of reticular fibers |
|
|
peyer's patches |
(aka lymphoid nodes) embedded in submucosa in the lining of an organ (ex. ileum, jejunum) beteween epithelium and smooth muscle |
