2. Compare the development of lymphocytes with other formed elements. B lymphocytes develop in red bone marrow‚ T lymphocytes develop in red bone marrow and mature in the thymus; the other formed elements develop in red bone marrow 3. What is erythropoiesis? Which factors speed up and slow down erythropoiesis? Erythropoiesis is the process by which red blood cells (erythrocytes) are produced.

In acute leukemia‚ the leukemic or blast cells function abnormally and accumulate in the peripheral blood‚ the bone marrow‚ the reticuloendothelial system‚ and sometimes the central nervous system. It is characterized by rapid onset and may be distinguished as lymphocyctic (lymphoblastic) or myeloid (Langhorne‚ 2011). Acute lymphocytic leukemia (ALL) results from
