The lack of a nucleus in red blood cells allows them to have more space to carry oxygen efficiently. This adaptation also enables red blood cells to have a discoid shape, which aids in their ability to navigate through small blood vessels.
Without a nucleus, red blood cells cannot divide. This means that they must be continuously manufactured to replace those that die. This process occurs in the bone marrow.
All mature red blood cells are anucleate. Immature red blood cells have a nucleus but eject them later in their development.

Red Blood Cell
Why red blood cells have no nucleus but still they called cell?
Red blood cells lose their nucleus as they mature in order to make space for more hemoglobin, the protein that carries oxygen. Even without a nucleus, they are still considered cells because they have a cell membrane and other cellular components necessary for their function of transporting oxygen in the bloodstream.
What is unusual about a red blood cell?
A red blood cell lacks a nucleus, mitochondria, and other organelles to make more space for hemoglobin, which carries oxygen. This unique structure enables the cell to be flexible and travel easily through narrow blood vessels to deliver oxygen throughout the body.
How does anucleate red blood cell make its proteins and enzymes?
Anucleate red blood cells make their proteins and enzymes while they are still developing in the bone marrow, where they have a nucleus to carry out protein synthesis. Once they mature and lose their nucleus, they rely on the proteins and enzymes already present in their cytoplasm to carry out their functions.
How does the anucleate condition of a red blood cell affect its lifespan?
The anucleate condition of a red blood cell means it lacks a nucleus, limiting its ability to repair itself. This can shorten its lifespan compared to nucleated cells. Red blood cells typically live for about 120 days before being removed by the body's immune system.
Why is a red blood cell called an anucleate?
Anucleate means without a nucleus. Red blood cells are called anucleate because they don't have any nuclei.

Red Blood Cell
What does anucleate mean?
Anucleate means lacking a cell nucleus. Cells that are anucleate may contain other organelles but they do not have a nucleus, which is where genetic material is typically located. Examples of anucleate cells include red blood cells and platelets.
What are the anucleate cells that function to transport oxygen to the body's cell are called?
Red blood cells, also known as erythrocytes, are anucleate cells that transport oxygen to the body's cells. They contain hemoglobin, a protein that binds to oxygen in the lungs and releases it in tissues where it is needed.

What is a cell that DNA is not found in?
DNA is found in every cell in every organism, even diseased cells.
Which blood cell has DNA?
All blood cells have DNA, which carries genetic information and is important for cell functions. White blood cells, red blood cells, and platelets all contain DNA, although red blood cells lose their nucleus during maturation and do not have a nucleus with DNA.
What goes into and out of the blood as it comes close to body cells?

What does anemia secondary to blood loss mean?
It means that the blood count is low because somebody was bleeding (as opposed to blood count being low due to, say, lack of red blood cell production or increased blood cell detruction.)
