1. Immune response: The spleen plays a crucial role in the immune system by producing and storing white blood cells called lymphocytes. These cells help in fighting off infections and diseases.

2. Filtration of blood: The spleen acts as a filter for the blood, removing old or damaged red blood cells, platelets, and other debris from the bloodstream. It also helps in recycling iron from these old cells.

3. Production of red blood cells: In certain situations, such as during fetal development or in cases of severe anemia, the spleen can produce red blood cells to compensate for the shortage.

4. Storage of platelets: The spleen stores a reserve of platelets, which are essential for blood clotting. In case of bleeding, the spleen releases these platelets into the bloodstream to help stop the bleeding.

5. Hematopoiesis: The spleen is involved in the production and maturation of certain types of white blood cells, such as monocytes and macrophages, which are important for immune response and defense against infections.

6. Removal of damaged or abnormal cells: The spleen identifies and removes abnormal or damaged cells, including cancer cells, from the bloodstream. This helps in preventing the spread of cancer and maintaining overall health.

7. Regulation of blood volume: The spleen acts as a reservoir for blood, storing a significant amount of blood that can be released into circulation when needed. This helps in maintaining blood volume and preventing hypovolemia (low blood volume).

8. Production of antibodies: The spleen is involved in the production of antibodies, which are proteins that help in recognizing and neutralizing foreign substances, such as bacteria or viruses. This contributes to the body's defense against infections.
