Blood dyscrasias relate to which hematopoietic processes?

Blood dyscrasias relate to which hematopoietic processes?

• A. Erythropoiesis, granulopoiesis, thrombopoiesis
• B. Lymphopoiesis
• C. Respiration and digestion
• D. Metabolism

Answer: (A)

Blood dyscrasias are disorders of the blood’s cellular components that arise from problems in hematopoiesis, the process by which blood cells are produced in the bone marrow. The major lineages involved are erythropoiesis (red blood cells), granulopoiesis (granulocytes such as neutrophils, eosinophils, and basophils), and thrombopoiesis (platelets). These three together account for the main blood cell types that can be disrupted in dyscrasias, which is why this option is the best fit. Lymphopoiesis (lymphocytes) is also part of hematopoiesis but the question emphasizes the primary formed elements commonly implicated in dyscrasias, whereas respiration, digestion, and metabolism are not hematopoietic processes.
