Final answer:
Leukocytosis is the correct term for the overproduction of white blood cells, while leukopenia refers to a deficiency, and polycythemia pertains to red blood cells. The correct option is 1) leukopenia
Step-by-step explanation:
The overproduction of white blood cells is referred to as leukocytosis. This condition involves excessive leukocyte proliferation, which even though increases the leukocyte count, often results in the production of cells that may be nonfunctional.
Such nonfunctional cells can leave the individual with an increased risk for disease. Leukopenia, on the other hand, describes a below-normal production of leukocytes which may prevent the body from effectively warding off disease.
Polycythemia is related to the excessive production of red blood cells (RBCs) and not leukocytes. It should not be confused with leukocytosis which specifically refers to overproduction of white blood cells. The correct option is 1) leukopenia
