Actually red blood cells do not have the longest life span of circulating blood cells - that would be differentiated memory B lymphocytes. RBCs actually have a relatively short circulating life span (about 4 months on average) because they lose their nuclei and most cellular organelles when they mature. This means the cell cannot repair damage to the cell membrane and eventually the cell becomes too damaged to function and is removed by the spleen.
They lack a nucleus and other organelles which would replace parts that are wearing out all this contributes to their short life span.
The reason why red blood cells live up to 120 days is because they lack organelles and a nucleus, which are required to keep a cell alive.
Red blood cells have a limited life span because they don't have a nucleus nor DNA.

What percentage of the body's iron is in erythrocytes?

Do reptiles have a nucleus in their erythrocytes?
They do. Mammals are the only vertebrates without a nucleus in their erythrocytes.
When the antigens on erythrocytes bind with antibodies in the plasma?
Agglutination and eventual lysis of erythrocytes occurs.
Is there RNA in erythrocytes?
no
Which of the following formed elements is the most abundant erythrocytes platelet basophils eosinophils lymphocytes?
erythrocytes
Which of the formed elements contains hemoglobin and transports respiratory gases?
I do believe that the answer is erythrocytes. Erythrocytes are the formed element in blood that transport oxygen and carbon dioxide.
What human cells can't have DNA extracted?
Red blood cells cannot have DNA extracted as they do not have a nucleus. This lack of a nucleus means that red blood cells are unable to replicate or repair themselves, and they have a limited lifespan.
