The spleen is an organ present in all humans.
Similar in structure to a large lymph node, it acts primarily as a blood filter.
Thus life is possible after the spleen is removed.
The spleen plays important roles in regard to red blood cells and the immune system.
It removes old red blood cells and holds a reserve of blood in case of hemorrhagic shock and also recycles iron.
As a part of the mononuclear phagocyte system, it metabolizes hemoglobin removed from senescent erythrocytes.
The globin portion of hemoglobin is degraded to its constitutive amino acids and the heme portion is metabolized to bilirubin, which is removed in the liver.
The spleen synthesizes antibodies in its white pulp and removes antibody-coated bacteria and antibody-coated blood cells by way of blood and lymph node circulation
These monocytes, upon moving to injured tissue turn into dendritic cells and macrophages while promoting tissue healing.
The spleen is a center of activity of the reticuloendothelial system and can be considered analogous to a large lymph node as its absence causes a predisposition to certain infections.
In humans, the spleen is brownish in color and is located in the left upper quadrant of the abdomen.
The spleen is located in the upper left part of the abdomen under the ribcage.
It works as part of the lymphatic system to protect the body, clearing worn-out red blood cells and other foreign bodies from the bloodstream to help fight off infection
The spleen also helps the body fight infection.
The spleen contains lymphocytes and another kind of white blood cell called macrophages which engulf and destroy bacteria, dead tissue, and foreign matter and remove them from the blood passing through the spleen.
The spleen helps control the amount of blood and blood cells that circulate through the body and helps destroy damaged cells.
The spleen is part of the lymphatic system.
