WebNucleated RBCs are called normoblasts. These are red blood cells that retain the cell nucleus. These cells are actually precursors for production of normal erythrocytes. These immature RBCs are commonly observed in neonates. Thus, nucleated red blood cells in newborns is not usually a cause for concern. These nucleated RBCs (NRBCs) are present ... WebJun 25, 2024 · 3 Answers. The absence of a nucleus is an adaptation of the red blood cell for its role. It allows the red blood cell to contain more hemoglobin and, therefore, carry more oxygen molecules. It also allows the cell to have its distinctive bi-concave shape which aids diffusion. This shape would not be possible if the cell had a nucleus in the way.

Mammal red blood cells (erythrocytes) contain neither nucleus nor mitochondria. Traditional theory suggests that the presence of a nucleus would prevent big nucleated erythrocytes to squeeze through these small capillaries.
