I. Choose the set of leukocytes which is predominantly found in the peripheral blood of healthy people.
1. Neutrophils, monocytes, lymphocytes, eosinophils, basophils.
2. Neutrophils, promonocytes, lymphocytes, eosinophils, basophils.
3. Neutrophils, promyelocytes, lymphocytes, eosinophils, basophils.
4. Neutrophils, metamyelocytes, lymphocytes, eosinophils, basophils.
II. Leukocytosis may result from the following:
1. Increased release from the storage pool in the marrow.
2. Demargination of neutrophils.
3. Decreased extravasation of leukocytes into tissues.
4. Expansion of marrow leukocyte precursor pool.
5. Splenomegaly.
6. Increased peripheral use of leukocytes.
7. Suppression of myeloid stem cells.
III. Leukopenia may result from the following:
1. Insufficiency of vitamin B12.
2. Splenomegaly.
3. Overwhelming bacterial, fungal or rickettsial infections.
4. Aplastic anemia.
5. Strenuous physical exercise.
