Spleen

The spleen is an important organ located in the upper left part of the abdomen, just below the diaphragm and behind the stomach. It is the largest organ of the lymphatic system and serves various vital functions in the body.

Functions of the Spleen

• Immune Function: The spleen plays a key role in the body's immune system. It acts as a filter for blood, removing old or damaged red blood cells and foreign particles, and producing white blood cells that help fight off infections.
• Blood Storage: The spleen acts as a reservoir for blood, particularly platelets, which are important for blood clotting.
• Red Blood Cell Production (Fetus): In the developing fetus, the spleen is involved in the production of red blood cells. However, this function diminishes as the fetus matures.

Common Disorders of the Spleen

Some common disorders associated with the spleen include:

• Splenomegaly: This refers to an enlarged spleen, which can occur due to various conditions such as infections, liver disease, or certain cancers.
• Splenectomy: In some cases, a surgical procedure called splenectomy may be performed to remove the spleen, often as a treatment for certain blood disorders or traumatic injuries.
• Splenomegaly: This refers to an enlarged spleen, which can occur due to various conditions such as infections, liver disease, or certain cancers.
• Other Disorders: The spleen can also be affected by disorders such as splenic infarction, where the blood supply to the organ is compromised, and splenic abscess, which is a collection of pus within the spleen.
