front 8 The least abundant white blood cell type is the | back 8 -basophil. |
front 9 B cells fight infections by | back 9 -producing antibodies. |
front 10 The replacement of red bone marrow with yellow bone marrow in the limbs occurs | back 10 -between 8 and 18 years of age. |
front 11 Which cells fight infection by producing antibodies? | back 11 -B lymphocytes |
front 12 Leukocytes, ordered from most to least abundant, are the | back 12 -neutrophils, lymphocytes, monocytes, eosinophils, and basophils. |
front 13 Most abundant formed element. | back 13 -erythrocyte |
front 14 Elevated numbers of reticulocytes may indicate | back 14 -a person is adapting to life at high elevations |
front 15 In the cell line that forms erythrocytes in red bone marrow, all of the following occur except that | back 15 -lysosome-like granules accumulate. |
front 16 Together, leukocytes and platelets constitute roughly which percentage of whole blood volume? | back 16 -1% |
front 17 Along with leukocytes, these contribute less than 1% of whole blood. | back 17 platelets |

front 20 The formed element that is flattened, circular, lacks a nucleus, lacks mitochondria or ribosomes, and is red because of the presence of hemoglobin is | back 20 -an erythrocyte. |
front 21 The blood's globulins include | back 21 -antibodies |
front 22 Reticulocytes are precursors to mature | back 22 -erythrocytes. |
