Question

Red blood cells have no nucleus then why do we call them cells?

Answer 1

Red blood cells:

1. Red blood cells are blood cells that are generated in the bone marrow and noticed in the blood.
2. Red blood cells contain hemoglobin, a protein that transports oxygenated blood to all parts of the body.
3. Red Blood Cells do not have a nucleus but are still regarded as cells.
4. It's because Red Blood Cells (RBCs) have a nucleus before they're even generated in the bone marrow.
5. They end up losing the nucleus in order to appease more hemoglobin and thus transit more oxygen.
