Which of these develops from lymphoid stem cells? monocytes granulocytes lymphocytes erythrocytes

From which cell do the granulocytes descend? monoblast promonocyte myeloblast lymphoid stem cell

What part of the pathway to produce platelets is shared with other formed elements? -hematopoietic stem cell (hemocytoblast) -megakaryoblast -lymphoid stem cell -reticulocyte

What triggers erythropoietin (EPO) production to make new red blood cells? reduced availability of oxygen a high hematocrit excess oxygen in the bloodstream too many platelets

What erythrocyte production disorder results from an autoimmune disease associated with vitamin B12 absorption? renal anemia hemorrhagic anemia pernicious anemia aplastic anemia

What protein involved in coagulation provides the activation for the final step in clotting? prothrombin activator fibrin fibrinogen thrombin

All lymphocytes are also leukocytes.

What factor stimulates platelet formation? erythropoietin thrombopoietin interleukin 2 plasmin

Which of the following represents a difference between extrinsic and intrinsic blood clotting pathways? -One involves calcium ions, while the other does not. -One is triggered by tissue damage, while the other cannot be triggered by tissue damage. -One is faster than the other. -One leads to the production of prothrombin activator and the other does not.

During which event of hemostasis do clotting factors (procoagulants) assist with the transformation of blood from a liquid to a gel?

What "clot buster" enzyme removes unneeded clots after healing has occurred during fibrinolysis? plasmin thrombin fibrin plasminogen

During erythroblastosis fetalis, a Rh- mother's anti-Rh antibodies that have crossed the placenta will cause agglutination of the fetus's Rh+ RBCs. However, the reverse problem never happens when a Rh+ mother is pregnant with a Rh- fetus, that is, antibodies produced by the fetus cannot cause agglutination of the mother's Rh+ RBCs. This is true because ______. -agglutinins are physically too large to pass across the placenta -fetal antibodies are immature and non-functional -antibodies that can cause this agglutination are not produced by a fetus -the placenta is a barrier that prevents the passage of all antigens
