What is the function of Erythrocytes (red blood cells)? To ferry oxygen and blood to all cells throughout the body. What is hemoglobin? An iron-bearing protein, transports the bulk of the oxygen that is carried in the blood.
Is RBC Multinucleated?
The nucleus is the largest and most prominent of a cell’s organelles (Figure 3.19). Interestingly, some cells in the body, such as muscle cells, contain more than one nucleus (Figure 3.20), which is known as multinucleated. Other cells, such as mammalian red blood cells (RBCs), do not contain nuclei at all.

Why is RBC in enucleated?
After synthesis, it undergoes a process called enucleation in which the nucleus is removed. The absence of a nucleus allows the red blood cells to contain more hemoglobin and hence all their internal space is available for oxygen transport in order to the body tissues.
