This is the type of organ that is in charge of the production of the blood cells. At the same time, it is also in charge of removing the blood cells that cannot be used by the body anymore. It has some effect in the immune system of humans and other vertebrates.
There are some who say that people cannot live without their spleen but it will be harder for their body to cope especially if they are exposed to a lot of bacteria all the time. If the spleen gets damaged, it will be removed in order to help the person survive but this person will be fighting off more infections for his/her life.
A spleen is an organ in the human body located in the upper left part of your abdomen, behind your ribs, under your diaphragm and above and behind your stomach. Its primary function is to filter your blood by storing and generating red and white blood cells.
The spleen helps regulate red blood cells (which carry oxygen) and platelets (which help blood to clot) by breaking down and removing cells that are abnormal, old or damaged. The spleen also stores and produces white blood cells which are used to fight off infections such as bacteria, viruses, or other germs that might be in your blood.
