Erythropoiesis is the process by which red blood cells (erythrocytes) are produced. If you lose a lot of blood, erythropoiesis will speed up; anemia can cause erythropoiesis to slow down. 4. Explain what would happen if a person with type B blood were given a transfusion of type O blood. Nothing type B can receive type O
5. What is the name and function of each WBC?
a. WBC has a round nucleus surrounded by a blue halo of cytoplasm with no visible granules. a) lymphocyte – major combatant in immune responses
b. WBC contains dense blue-purple granules that hide the nucleus. b) basophil – intensifies the inflammatory reaction, is involved in hypersensitivity reactions
c. WBC has a U-shaped nucleus and a bluish, foamy cytoplasm with no visible granules. c) monocyte – phagocytosis and cell debris cleanup
d. WBC contains small, pale lilac granules and a four-lobed nucleus. d) neutrophil – active in phagocytosis
e. WBC contains red-orange granules and a two-lobed nucleus. 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. Why would the level of leukocytes be higher in an individual who has been infected with the parasitic disease?
