"Haematopoiesis (from Greek αἷμα, "blood" and ποιεῖν "to make"; also hematopoiesis in American English; sometimes also haemopoiesis or hemopoiesis) is the formation of blood cellular components. All cellular blood components are derived from haematopoietic stem cells. In a healthy adult person, approximately 10 –10 new blood cells are produced daily in order to maintain steady state levels in the peripheral circulation. " - Ontogeny of the hematopoietic system
