THE SPLEEN HAS THREE MAIN ACTIONS3: 1. Sequestration: The reticular meshwork of the cords in the red pulp trap cells by creating adhesion to them and then filter out the senescent or poorly formed redblood cells 2. Phagocytosis: Irreversible uptake of antibody-coated particulates and other foreign matter in preparation for antigen presentation. Hence a patient who has undergone a splenectomy will be prone to bacterial sepsis from encapsulated organisms. Phagocytosis can also be performed on antibody platelets and red blood cells, essentially trapping and destroying them, in conditions such as Immune Thrombocytopenia and hemolytic anemia and that can be an indication for a splenectomy. 3.…show more content…
