WebEach day added to mean RBC lifespan prevents the destruction of 10 11 cells (around 1% of the total population), which is equivalent to the daily production of RBCs in normal conditions. A significant fall in the number of RBCs after a haemorrhage may produce a deficit of oxygen in the tissues. WebOther factors may also play a role in regulating RBC production including iron, vitamin B12, and folate. Iron is needed for hemoglobin to carry oxygen throughout the body. Vitamin B12 and folate are substances that help produce new RBCs. The liver removes excess iron from the bloodstream using proteins called "transferrin" for storage.
