Cards in this set: Term What is the difference between plasma and serum? Definition Plasma is the liquid of centrifuged blood. Serum is plasma minus the clotting factors. Term What are the four criteria for recognizing and distinguishing WBCs? Definition a) morphology of nuclei b)presence/ absence of granules and their color c) size of cell d) relative abundance Term Name the granulocyte WBCs Definition Neutrophils, Eosinophils and Basophils Term Name the agranulocyte WBCs Definition Lymphocytes and Monocytes Term What is the most abundant WBC? Definition the Neutrophils (60-70% of all WBCs) Term Which is the largest WBC? Definition Monocytes are the largest Term Which WBC is responsible for phagocytosis? Definition Neutrophils. They are capable of creating reactive oxygen species (O2, H2O2 and HOCl) to help in that process Term Which WBC is chemotactic to parasites? Definition Eosinophils Term Define Hemopoiesis Definition Hemopoiesis is the formation of blood cells (from stem cells) Term What color bone marrow do adults have? Definition Adults have yellow bone marrow, which has low RBC production. Infants have red marrow, which makes lots of RBC. In times of need, adults may switch to red marrow. Term There are six stages in the erythropoietic series (proerythroblast -> erythrocyte). What is the best way to distinguis between the different phases? Definition Size. Erythrocytes are the smallest. Only reticulocytes and erythrocytes are anucleated. Term Platelets (aka __________) are disk shaped cell fragments of much larger ____________. Definition 1) thrombocytes 2) megakaryocytes Term List four major features of RBCs Definition 1) no nucleus 2)durable 3) deformable (can compress) 4)elastic (can return to original shape) Term What is an anemia? Definition Anemia is a decreased functional capacity of blood to deliver O2 to tissues/cells Term Anemia may be caused by a decrease in numbers of RBCs. What can cause a decrease in RBCs? Definition RBC decrease can be caused by: a) blood loss b)hemolytic anemia (abnormal breakdown of RBCs) c) ineffective erythropoieses (new RBC formation) Term Anemia may be caused by an insufficient amount of functional hemoglobin. What causes dysfunctional Hb? Definition a) hemoglobinopathies b) defect in heme synthesis c) iron deficiencies Term _______________ is an anemia associated with erythrocytes of reduced size and hemoglobin content. Definition Microcytic hypochromic anemia Term __________ is an anemia caused by low numbers of large RBCs. Definition Macrocytic anemia Term In a CBC, the ______________ gives the volume of red blood cells/volume of blood. Definition Hematocrit
