Leukocyte

(general)

Granulocyte

(general), contain the suffix “-phil”

Neutrophil

3 or 4 lobed nucleus with faintly colored granules

Neutrophil

Eosinophil

bilobed nucleus with bright pink granules

Eosinophil

Basophil

dark purple granules making nucleus and cytoplasm hard to see, same size as erythrocytes

Basophil

Agranulocyte

(general)

Lymphocyte

same size as erythrocytes, thin band of clear cytoplasm around a spherical nucleus

Lymphocyte

Monocyte

largest leukocyte (double erythrocyte), lots of clear cytoplasm and a c-shaped nucleus

Monocyte

Red bone marrow

Megakaryocyte

Megakaryocyte

Megakaryocyte

Thrombocyte

platelet

Hematocrit

the percentage by volume of red cells in your blood

polycythemia

a blood cancer which causes the bone marrow to make too many red blood cells. This results in thickening of blood causing serious complications like blood clotting.

antigen

a toxin or other foreign substance which induces an immune response in the body, bonds to antibodies

antibody

a blood protein produced in response to and counteracting a specific antigen; combine chemically with substances which the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood.

clumping

the process that occurs if an antigen is mixed with its corresponding antibody

transfusion reactions

include urticaria, fevers, and hemolysis caused by antibodies in the recipient directed against components of the transfused product, including antigens on the red blood cells (RBSc) themselves, plasma proteins, or antigens on contaminating white blood cells or platelets.

universal donor

O- because it has no antigens

universal recipient

AB+ because it already has all of the antigens

megakaryocyte

in red bone marrow

38-46% 42-54%

Hematocrit Relative values female male

formed elements

all the cells in blood

plasma

liquid portion of blood

buffy coat

leukocytes (white blood cells) in a hematocrit

polycythemia

producing too many erythrocytes elevating hematocrit

anemia

not enough healthy erythrocytes to carry enough oxygen

sickle cell anemia

abnormally shaped erythrocytes

iron deficient anemia

not enough dietary iron causing empty looking erythrocyes

anucleate

Lacking a nucleus

biconcave

Indented on two side
