Spleen

The spleen is an important organ located in the upper left part of the abdomen, under the rib cage. It is a part of the lymphatic system and plays a crucial role in filtering the blood, storing red blood cells and platelets, and producing white blood cells.

Functions of the Spleen

• Filtering the blood: The spleen helps remove old or damaged red blood cells and platelets from the bloodstream.
• Immune function: It plays a role in the body's immune response by producing and storing white blood cells, which help fight infections.
• Blood storage: The spleen acts as a reservoir for red blood cells and platelets, releasing them into the bloodstream when needed.

Common Disorders of the Spleen

Some common disorders associated with the spleen include:

• Splenomegaly: Enlargement of the spleen, often due to various underlying conditions such as infections, liver disease, or blood disorders.
• Splenectomy: Surgical removal of the spleen, which may be necessary in cases of trauma, certain blood disorders, or cancer.
• Splenomegaly: Enlargement of the spleen, often due to various underlying conditions such as infections, liver disease, or blood disorders.
