Why is the spleen part of the immune system?

Answer 1

The spleen is a purplish red organ located in the upper left part of your abdominal cavity. The spleen is an integral part of the immune system. The spleen filters blood, removes old or damaged platelets and red blood cells, stores blood, and forms some types of white blood cells. If the spleen is damaged it can be removed. You can live without your spleen, but your resistance to infection will be lowered.

Answer 2

The human spleen is an organ that creates lymphocytes for the destruction and recycling of old red-blood cells. The spleen is also a blood reservoir. It supplies the body with blood in emergencies such as a bad cut. The spleen is also the location where white blood cells trap organisms. It works as part of the lymphatic system to protect the body, clearing worn out red blood cells and other foreign bodies from the bloodstream to help fight off infection.

Answer 3

The spleen is part of the immune system because it makes humans less vulnerable to infections. The spleen has two components, the red pulp and the white pulp.
