New red blood cells are produced in the bone marrow at a rate that matches the destruction of older cells. 1. This is achieved by means of homeostatic mechanisms that control the ratio between cell production and destruction and compensate any unbalance between oxygen supply and demand by increasing or reducing the number of circulating RBCs [1,2].

In asplenic patients, other mononuclear phagocytic cells in tissues and in circulation may function in this capacity. A red blood cell may be destroyed because it is old and the new cells have replaced it or there may be an inherent problem in the body that is causing them to be destroyed before time. 1 Answer Ahmed(Medical Genetics Academy) Sep 1, 2016 Old red blood cells are removed from the blood by the spleen and liver. https://www.pediatriconcall.com/articles/pediatric-hematology/ When blood cells are broken down: Choose the CORRECT statement.
