Answer: spleen
Step-by-step explanation:
The spleen, the body's largest lymphoid organ, is located in the left hypochondrium, under the protection of the costal arch. It varies in volume according to age, nutritional status, and immune system, in adults it weighs about 150g. The basic functions of the spleen are fundamentally hematological and immunological. From the hematological point of view, we can emphasize that the organ acts as a filter: through the destructive removal of senescent or defective red blood cells from the circulation based on the unique organization of its parenchyma and vasculature. It also acts in the regulation of blood flow to the liver, blood cell storage and endogenous iron.
