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.
As you've seen, your spleen is a very useful organ, but it is not vital. Sometimes, a person's spleen does have to be surgically removed. This may be because the spleen becomes injured, or it may be taken out in the course of transplanting other organs. Other parts of your body, like your lymph nodes and your liver, are able to step in and take over many of your spleen's functions.
