Unit 1.2 heme

progenitor cell erythrocytes derived from

major function of mature erythrocyte

Erythropoietin

first cell identifiable as being in erythrocyte series

Pronormablast (rubriblast)

Basophilic normoblast (prorubricyte)

polychromatic normoblast

orthochromic normoblast (metarubircyte)

Reticulocyte (retic) (polychromatic erythrocyte)

mature erythrocyte

Maturation stages of:

Period of time marrow reticulocyte remains in bone marrow prior to release (normal cond.)

Period of time blood reticulocyte continues to mature in blood after release (normal cond.)

Normal red cell

reason(s) for red blood cell senescence
