Study Notes

Hematopoiesis

The process of creating circulating red blood cells (RBCs), white blood cells (WBCs), and platelets from undifferentiated stem cells.
Requires a constant supply of iron, vitamin B12, and folic acid as well as hematopoietic growth factors such as erythropoietin and colony-stimulating factors.
Insufficient essential nutrients or growth factors can lead to deficiency of functional blood cells.

Anemia

Defined as a low hemoglobin (Hb) concentration due to decreased production or increased loss of RBCs.
The World Health Organization (WHO) defines anemia as Hb concentration below 13 g/dL in men and 12 g/dL in women.
Anemia is a prohibited substance in the Olympics due to its effects of increasing RBC concentration for improved oxygen delivery and athletic performance.
