Red blood cells are released from the spleen into blood circulation to help compensate for blood loss. The spleen is a lymphatic organ that performs the valuable function of filtering blood. While it is an important organ, it can be removed when necessary without causing death. This is the case because other organs, such as the liver and bone marrow, can perform filtration functions in the body.
The spleen is a vital organ, which plays a huge role in the immune system. The spleen is located in the abdomen of the body, where it functions in the destruction of old red bâ¦lood cells and holds a reservoir of blood. Until 1993, the purpose of the spleen was not known.
