MICROANATOMY

Detailed explanation-1: -RBCs lack nucleus. It enables the red blood cell to possess more oxygen-carrying haemoglobin, thus enabling more oxygen to be transported in the blood and boosting the metabolism.

Detailed explanation-2: -CAMBRIDGE, Mass. – Unlike the rest of the cells in your body, your red blood cells lack nuclei. That quirk dates back to the time when mammals began to evolve. Other vertebrates such as fish, reptiles and birds have red cells that contain nuclei that are inactive.

Detailed explanation-3: -Red blood cells don’t have a nucleus like white blood cells, allowing them to change shape and move throughout your body easier.

Detailed explanation-4: -By contrast, the red blood cells of mammals lack nuclei and other internal structures found in most animal cells. This simplification allows mammal red blood cells to carry more gas-transporting proteins and to squeeze through smaller blood vessels.
