Relating to the process of producing blood cells in the body.
The hemopoietic tissue in the bone marrow is essential for blood cell formation.
Hemopoietic → It is formed from "hemo-" (from Greek "haima", meaning blood) and "poietic" (from Greek "poietikos", meaning relating to making or producing). The word "hemopoietic" refers to the process of producing blood cells.
Think of 'blood' ('hemo-') being 'made' ('poietic') — that's why hemopoietic relates to the production of blood.
