The entire system of red blood cells in the body, including both mature red blood cells and the cells that produce them.
From Greek erythro- (red) + -on (suffix forming nouns). A medical term created to describe the collective red blood cell system as a unified physiological unit.
Scientists use 'erythron' to think about your red blood cells as one interconnected system rather than individual cells, which helps them understand how diseases affecting the whole system (like certain cancers) work differently than isolated problems.
