Study Notes
Erythropoiesis
- Erythropoiesis occurs in the following anatomical sites: bone marrow, spleen, and liver (in the fetus)
- The primary stimulus for the production of RBCs is hypoxia (low oxygen levels)
RBC Maturation Stages
- The series of RBC maturation stages is referred to as erythropoiesis
- The earliest recognizable RBC precursor is the pronormoblast (or proerythroblast)
RBC Maturation Stage Characteristics
- The stage of RBC maturation that produces hemoglobin but is not detected in light microscopy is the normoblast (or erythroblast) stage
