What is the process that forms blood cells called?

The process that forms blood cells is known as hematopoiesis. This is a crucial physiological function occurring primarily within the bone marrow, where multipotent stem cells differentiate into various types of blood cells, including red blood cells, white blood cells, and platelets. Hematopoiesis encompasses the entire spectrum of blood cell development and is vital for maintaining normal blood cell counts and function throughout life.

In contrast, while hemoglobin synthesis refers specifically to the production of hemoglobin within red blood cells, it does not encompass the entire process of blood cell formation. Similarly, erythropoiesis is a subset of hematopoiesis focusing solely on the formation of red blood cells, and leukopoiesis pertains specifically to the production of white blood cells. This distinction is what affirms hematopoiesis as the overarching process involved in the formation of all types of blood cells.
