Red and white blood cells develop from a common hematopoietic
stem cell, which is large and nucleated. After cell differentiation
and maturation, red cells no longer have nuclei and are very small,
and white cells are nucleated, often large, filled with granules,
and are capable of phagocytosis. Why do mature red blood cells look
so different from their white counterparts?
What is the term for white blood cells? How many types are there
and what does each one do?...
