We need to talk about red blood *** cells are defined as cells containing distinct nuclei and other membranous ***,red blood cells(RBCs)lack a nucleus and organelles—perhaps to limit the generation of reactive oxygen species(Zhang et al.,2011)—and are filled with hemoglobin(Hb).This oxygen carrier is limited to the cytosol by the cell membrane and cytoskeleton,which maintain cellular integrity and deformability as RBCs pass through narrow capillaries(Gratzer,1994)to perform their primary function of gas exchange.
