Blood Components: Questions and Answers
1.) Significance of a lower-than-normal hematocrit?
-means your body is not fighting off something, but puts you at risk for problems with bone marrow or puts you at risk for a bacterial infection. anemia What is the effect of a bacterial infection on the hematocrit? -raises them 2). Development of lymphocytes with the development of the other formed elements
-B lymphocytes develop in red bone marrow, T lymphocytes develop in red bone marrow and mature in the thymus; the other formed elements develop in red bone marrow 3.) Erythropoiesis? -the production of RBCs Which factors speed up and slow down erythropoiesis?
-when oxygen delivery to the kidneys falls and slows down when there is sufficient oxygen-carrying capacity of the blood 4.) What happens if a person with type B blood gets type O? -nothing 5.) Name and function of ea. WBC?
a.WBC has a round nucleus surrounded by a blue halo of cytoplasm with no visible granules.

d. WBC contains small, pale lilac granules and a four-lobed nucleus.
e. WBC contains red-orange granules and a two-lobed nucleus.
a) lymphocyte – major combatant in immune responses
b) basophil – intensifies the inflammatory reaction, is involved in hypersensitivity reactions
c) monocyte – phagocytosis and cell debris cleanup
d) neutrophil – active in phagocytosis
e) eosinphil – releases enzymes that combat the effects of histamine and other mediators of inflammation in allergic reactions, phagocytize antigen-antibody complexes, are effective against certain parasitic worms 6.) Level of leukocytes higher when infected with a parasitic disease?
-The presence of the parasitic microorganisms trigger an immune response in the body of the infected individual. The leukocytes are then produced in large amounts in
