ORIGIN OF THE BLOOD BONE MARROW
ORIGIN OF THE BLOOD The kidneys for synthesize the peptide hormone erythropoietin (EPO), which is an essential factor for the stimulation of RBCformation.EPO is produced in the renal tissue and released to the blood circulation to promote the maturation cycle of immature RBCs in the bone marrow. Without nucleus, RBC die quickly, about 120 days and need constant replacement.
