Erythema (from the Greek erythros, meaning red) is redness of the skin or mucous membranes, caused by hyperemia (increased blood flow) in superficial capillaries. It occurs with any skin injury, infection, or inflammation. Examples of erythema not associated with pathology include nervous blushes.
Describe the process of erythropoiesis. -pluripotent stem cell becomes an erythrocyte colony-forming unit (ecfu) -the hormone erythropoietin (EPO) stimulates the ecfu to develop into an erythroblast. -erythroblast (aka erythrocyte precursors) develop a nucleus, ribosomes, golgi, as well as hemoglobin.
