Red blood cell production or erythropoiesis occurs in the fetus in the yolk sac, liver, spleen and in adults in the red bone marrow.
The number normally remains stable. There is a negative feedback mechanism involving the hormone erythropoietin, which is produced and secreted by the special cells in the kidney and liver.
Erythropoiesis is the process of the formation of red blood cells and it occurs when the blood oxygen level falls below the homeostasis level. It is stimulated by hypoxia (i.e. inadequate oxygen delivery) due to decreased number of red blood cells, decreased amount of hemoglobin,and decreased availability of oxygen. The kidneys as well as the liver to a smaller extent will release erythropoietin which will stimulate red bone marrow and enhance erythropoiesis. Enhanced erythropoiesis will increase the number of red blood cells and the oxygen-carrying ability of blood. The blood oxygen level will return to homeostasis level.
-Stem cell differentiates
-Synthesis of hemoglobin begins
-Cell loses its nucleus
-Mature cell enters the blood stream.
Hypoxia in the blood triggers erythropoiesis.
erythropoiesis
Hemopoiesis is the term used to describe the formation of all blood cells. Erythropoiesis is the term used to describe only the formation of red blood cells.
the kidneys detect low levels of oxygen in the blood
Erythropoiesis is the production of red blood cells.
Hypoxia in the blood triggers erythropoiesis.
Erythropoiesis requires B12, Folic acid and iron.

Anemia
thalassemia
There are three main events that are considered stimuli for erythropoiesis. These are aerobic exercises, living in an environment with a high altitude, and hemorrhages.

Erythropoiesis (production of red blood cells) will occur when there are not enough red blood cells (RBCs) in circulation. Therefore the stimulation for erythropoiesis to occur is too few RBCs in the blood, which can be termed 'anaemia'.
