One of the spleen’s main jobs is to filter your blood. It affects the number of red blood cells that carry oxygen throughout your body, and the number of platelets, which are cells that help your blood to clot. It does this by breaking down and removing cells that are abnormal, old, or damaged.
Spleen cancer typically develops when cancer in another part of the body, most often lymphomas and leukemia, spread to this fist-sized organ. The spleen is under the rib cage on the left side of the body. It is part of the lymphatic system and plays a part in helping the body fight off disease.
The human spleen is about the size of a fist and is tucked under the left ribcage. It usually cannot be felt as most of it is shielded by the ribs. The spleen is a reservoir of blood and when needed, blood can be ‘squeezed’ out and enter the circulation. However, one of the main functions of the spleen is to filter blood.This diagram with labels depicts and explains the details of Spleen In Humans.
