haematopoiesis
C2CEFR level
95/100Rarity: very rare
TechnicalRegister
The formation and maturation of all cellular blood components from haematopoietic stem cells, chiefly in the bone marrow.
In myelofibrosis, marrow scarring drives haematopoiesis into the spleen and liver, causing organomegaly.
Rarity runs from 0 (a word everyone knows) to 100 (almost never seen outside specialist or literary writing). Level is the word's real difficulty on the CEFR scale, from A1 to C2.
