During this disease, why does anemia occur despite increased white blood cell production?

Are not responsible for the anemia Uses nutrients from other cells Have an abnormally short life span of cells Crowd red blood cells

Correct Answer:

Crowd red blood cells

Explanation:

In leukemia, anemia happens because the marrow is overtaken by proliferating white cells, which crowd out red blood cell precursors. This reduces erythropoiesis, so fewer red blood cells are made even though white blood cell production is high. The problem isn’t that red cells die faster; it’s that they aren’t produced in enough numbers due to marrow crowding by leukemic cells.
