Explanation: 

Detailed explanation-1: -The spleen has a few important functions. It fights any invading germs in the blood (the spleen contains infection-fighting white blood cells). It controls the level of blood cells. The spleen controls the level of white blood cells, red blood cells and platelets (small cells that form blood clots).

Detailed explanation-2: -Common causes include: Infections. Viral infections such as mononucleosis and HIV, bacterial infections such as tuberculosis and endocarditis and parasite infections such as malaria and toxoplasmosis stress the immune function of the spleen. They can cause it to overproduce antibodies and immune cells (hyperplasia).

Detailed explanation-3: -Your spleen also plays an important part in your immune system, which helps your body fight infection. Just as it detects faulty red blood cells, your spleen can pick out any unwelcome micro-organisms (like bacteria or viruses) in your blood.
