though agglutination damages organs what does it do the most damage to?
kidneys
what do granulocytes contain?
cytoplasmic granules
what does agglutination do to erythrocytes?
damages them
what do agglutinins do?
bind to antigens
what is the lymph node enclosed by?
a fibrous capsule
What is white pulp?
lymphatic tissue and the purple dots within it are darkly stained nuclei of lymphoid tissue
what do agranulocytes not have?
cytoplasmic granules
what is the stroma formed by?
a network of reticular fibers that extend from trabeculae
what are normal ranges for hematocrit?
males 40-50% and females 36-45%
what are the trabeculae of the fibrous capsule?
extensions which divide the lymph node into small compartments
where is an antigen?
on the surface of a blood cell
what are leukocytes (white blood cells)?
protecting the body against disease
how are some of the cells of the cortex arranged?
in masses known as germinal centers
what is agglutination?
when there is an antigen-antibody reaction which causes the red blood cells to clump together
what are the 2 types of lekocytes?
agranulocytes and granulocytes
what are agglutinogens?
genetically determined antigens on the surface of every individual’s erythrocyte.
what is the presences of agglutinogens determined by?
testing the erythrocytes with antibodies
what are the dark blue circles you’ll observe scattered in the red pulp?
white pulp
what materials do you need for blood typing? (6) (ASPTL)
1) alcohol prep pad 2) sterile lancets 3) plastic blood typing slide 4) toothpicks 5) blood typing antisera (Anti- A, Anti-B and Anti-D (Rh) 6) light box
what is hematocrit?
the percentage of the total blood volume that is comprised of packed red cells.
what is the tissue that makes up the lobules referred to as?
red and white pulp
what is the average hematocrit range for the class of females?
43%
what should we note from the inner medullar?
that the cells are arranged in lines
what materials do you need for determining hematocrit? (3) (SAH)
1) sterile lancet 2) alcohol prep 3) heparinized capillary tube
what are aglutinins?
antibodies in blood type reaction
what does the stroma of the lymph node do?
supports the cellular components
what are the normal ranges for leukocytes?
1) neutrophils- 60-70% 2) lymphocytes 25-30% 3) monocytes 3-8 % 4) esoinophils 2-4 % 5) basophils 0.5-1%
what do the exercise based on these agglutination reactions determine?
blood types
what do granulocytes consist of?
neutrophils, basophils and eosinphils
what is the lympoid nodule?
a compact mass of lymphoid cells and appears as a large collection of purple circles
what are lymphoid nodules also known as?
peyer’s patches
what are the cells that are arranged in lines referred to as?
cords
where does the trabeculae extend into?
the spleen and divide into lobules
what is the cortex (germinal layer)?
the outer region of the lymph node
what do agranulocytes consist of?
monocytes and lymphocytes
what is the trabeculae?
inward extension of the capsule
