According to the National Medical Library (NLM), the spleen is on the left side of the body just above the kidneys and is the largest lymphoid organ. "The spleen functions as a blood filter and controls the amount of erythrocytes and blood stored in the body and helps prevent infections," said Jordan Norton, senior nurse at the University of Florida Health Shadows. . When the hospital spleen detects potentially dangerous bacteria, viruses or other microbes in the blood, it produces white blood cells called lymphocytes together with the lymph nodes. This serves as a defense against intruders. Lymphocytes produce antibodies to kill foreign microbes and prevent the spread of infection. Those who have lost the spleen due to illness or injury are more likely to be infected, but humans can live without the spleen.
