In the present work we studied the erythropoietic response to chronic phlebotomy-induced anemia and changes in cellular and systemic body iron distribution. Female mice (CF1 strain, n =32) were divided into control and experimental groups, following a paired experimental design. Iron distribution in spleen and liver during chronic phlebotomy was assessed by morphological studies and erythropoietic activity by hematological studies. Statistical differences were determined by Student test. The significance level was set at p
