The spleen is a lymphoid organ in the left upper quadrant (LUQ) of the abdominal cavity. The white pulp contains lymphocytes, the red pulp contains macrophages. The spleen is part of the phagocytic/immunologic system that surrounds, engulfs, and destroys invading pathogens.
In anemia states the spleen can produce erythrocytes but the anemia must be severe before the spleen assists in this function. In health the spleen is not a primary source of hematopoiesis. The white pulp traps foreign antigens, this causes the release of antibodies and lymphocytes. Macrophages in the spleen remove old or damaged cells and cell debris.
The spleen also acts as a reservoir for blood and contains a high amount of platelets or thrombocytes which are needed for normal blood clotting.
Spleen is an organ in human body that plays an important part in the circulatory and immune system. It the about the size of the fist and is located behind and to the left of the stomach.
Spleen helps filter unwanted substances from the blood by destroying the old and damaged blood cells in the blood. It also helps fighting infection by getting rid of certain parasites and bacteria in the blood stream.
Also spleen releases special proteins called antibodies into the blood. These antibodies, weaken or kill bacteria, viruses, and other substances that cause infection
The spleen is an organ, found in the human abdomen. The spleen has functions as part of the immune system and it contributes in the production and storage of blood cells as part of the circulatory system. Though the spleen is a very important organ it is not vital for human survival.The spleen removes old red blood cells, which are called erythrocytes, from the blood supply and removes, stores and produces white blood cell called lymphocytes. The lymphocytes stored in the spleen produce antibodies and aid in removing microbes and other foreign bodies. In case the spleen has to be removed most of its functions can be taken over by the liver. There is an increased susceptibility to infections though as the the liver cannot compensate for this function.
