How the body disposes of the hemoglobin from RBCs and the relation between this and bile pigments, fecal pigments, and the pigment of the urine. Introduction: The body is endowed with mechanisms to detect changes in its internal environment, to antagonize the changes, and to ultimately maintain a fairly constant internal environment. These mechanisms together are termed as homeostasis – the maintenance of a constant internal environment. The number of RBCs in the blood is maintained at a constant level by a balance between the supply of new RBCs by erythropoiesis and RBC death and degradation, which happens around their 120-day life.
