Which image shows the type of leukocyte responsible for antibody production?
D

What type of connective tissue cells are similar to basophils in that they contain granules that release histamine to mediate the inflammatory response?
Mast cells
Blood is a type of connective tissue. What primary germ layer is responsible for producing both blood cells and phagocytic brain glial cells?
Mesoderm
Which of these is true of the materials making up the buffy coat in centrifuged blood?
They are intermediate in density between erythrocytes and plasma
Which of the following best explains how platelets enter the blood?
They are passed through the wall of a bone marrow capillary.
Which part of the hemoglobin molecule binds carbon dioxide for transport?

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 ______.
antibodies that can cause this agglutination are not produced by a fetus
hemo
blood
Which of these is most likely in the event of excessive consumption of erythrocytes by macrophages?
blood levels of bilirubin would rise
Erythropoietin (EPO) stimulates the developmental process shown here. What part of the body does erythropoietin (EPO) target to increase erythropoiesis?
bone marrow
myelo
bone marrow
thromb
clot
embal
embolus or wedge
What part of the pathway to produce platelets is shared with other formed elements?
hematopoietic stem cell (hemocytoblast)
Which of the following is not a function of blood?
hormone production
myeloblast
immature bone marrow that gives rise to granulocytes
From which cell do the granulocytes descend?
myeloblast
In a cancer patient undergoing chemotherapy, the decision to utilize a CSF capable of specifically stimulating the production of only the granular leukocytes would require that the CSF acts exclusively on ______.
myeloblasts
Which cells of the myeloid stem cell pathway have accumulated granules?
myelocytes
Identify the leukocytes in the figure in order.

embolism
the sudden blockage of a blood vessel by an embolus
