The spleen.
Red blood cells are taken out of circulation in the spleen. Their iron is recycled and stored in the liver.
The spleen identifies "old" erythrocytes (RBCs) and destroys them. The life of an RBC is around 120 days.
The spleen is responsible for breaking down red blood cells. The hemoglobin is then recycled by the liver.
Yes, red blood cells are recycled every 100-120 days.
The old red blood cells get replaced by the newly formed red blood cells.
Blood cells are born in the bone marrow and are delivered into the bloodstream to begin work. Blood cells only live a limited time in the blood. Old blood cells are destroyed by a type of cell called a macrophage. Macrophages are the trash collectors of the body and are, in fact, blood cells themselves.
It is actually the spleen that filters out old and useless red blood cells.

All cells are born with a nucleus, but not the red blood cell. Without the large structure in the cell, it can carry more oxygen. But without a nucleus, it cannot reproduce and will die eventually. A red blood cell's life span is about 3-4 months. After that, it will be sent to the liver to be destroyed.When red blood cells are destroyed they release heme, a prosthetic group, that consists of iron. Iron is used to reproduce red blood cells in bone marrow. Red blood cells usually are reproduced in bone marrow.
