| I develop from a proerythroblast | Erythrocyte (RBC) |
| I am a biconcave disc with no nucleus. | Erythrocyte (RBC) |
| My main job is carrying oxygen to cells. | Erythrocyte (RBC) |
| I am formed by budding off a large cell called a megakaryocyte. | Platelet (thrombocyte) |
| My precursor cell is a megakaryoblast. | Platelet (thrombocyte) |
| I function in hemostasis and blood coagulation. | Platelet (thrombocyte) |
| In stucture, I am a tiny package made of membrane with granules inside. | Platelet (thrombocyte) |
| I develop from a monoblast. | Monocyte |
| I am a large cell with foamy blue cytoplasm and a nucleus that varies in shape from a lima bean to a horseshoe. | Monocyte |
| I circulate in the blood as a monocyte. When I leave the blood, I change to a ____ and become highly phagocytic. | Macrophage |
| I do a great job of phagocytizing bacteria, dead tissue, and debris. | Macrophage |
| I develop from a myeloblast. | Neutrophil |
| I have pale lilac granules and a lobed nucleus. | Neutrophil |
| I may be called a polymorphonuclear leukocyte, a polymorph, or a poly. | Neutrophil |
| I am the most plentiful type of WBC, making up 60 - 70 % of the total WBC. | Neutrophil |
| I rush to the site of an injury, arriving in large numbers in a matter of minutes. My specialty is phagocytosis of bacteria. | Neutrophil |
| I develop from an eosinophilic myeloblast. | Eosinophil |
| I have reddish-orange granules in my cytoplasm, and usually a bilobed nucleus. | Eosinophil |
| I help defend you against parasitic worms (yuck). | Eosinophil |
| My numbers go up when you have a severe allergy. | Eosinophils |
| I phagocytize antigen-antibody complexes. | Eosinophil |
| I develop from a basophilic myeloblast. | Basophil |
| I am the scarcest of WBC--you may not see me at all on a differential white count. | Basophil |
| I have large, bluish-black granules. | Basophil |
| I release histamine and intensify allergic reactions. | Basophil |
| I develop from a lymphoid stem cell. | Lymphocyte (B & T) |
| I change to a plasma cell and secrete antibodies as my part of the immune response. | B lymphocyte (B cell) |
| I become able to directly attack and destroy invaders as my part of the immune response. | T lymphocyte (T cell) |
| I have a large round purple-stained nucleus and a little bluish cytoplasm. | Lymphocyte |
| I am the slightly immature form of the RBC that enters the blood and matures in 1 -2 days. | Reticulocyte |
