Where Is The Spleen Located?

The spleen is generally soft and has a purplish color and is located under your ribcage and at the top of the stomach at the left higher abdomen quadrant. It can be found precisely between the ninth and eleventh ribs. It consists of two kinds of tissue, white pulp, and red pulp tissues. The red tissue is responsible for filtering the blood to get rid of damaged or old RBCs. The white tissue, on the other hand, is made up of the immune T and B cells, it fights infection alongside the immune system.


The spleen filters blood and controls the number of RBCs in it. It also helps the body to store up blood and to fight against infections. When potentially harmful bacteria, microorganisms, or viruses get into the blood. It detects them immediately and it teams up with the nodes of the lymph to create a group of white blood cells known as lymphocytes. Together they act in defense against these intruding invaders. These lymphocytes produce certain components known as antibodies that kill off foreign bodies and prevent infections from disseminating around the body.

Medical studies have found out that the flow of blood into your spleen causes the RBCs to go through narrow pathways inside the organ. Healthy RBCs pass through with ease while the damaged or old RBCs are destroyed by the waiting WBCs. It is a good organ because while it breaks down these blood cells it saves their useful components like iron so that it can be used again in the new cells.

The spleen also can increase its size for blood storage. This organ can be narrowed or widened depending on what the body needs per time. The amount of blood that can be reserved in the spleen is up to one full cup.

Instead of spleen breakage, there is also a laceration that can occur. The word laceration describes a lower degree of injury whereby only a portion of the spleen gets damaged. The highest degree of spleen breakage is a ruptured spleen.

The symptoms of a ruptured or lacerated spleen include tenderness or pain around the region where it is located that is the left wall of the chest, left shoulder, and the left abdomen side.

A higher degree of ruptures or lacerations may require surgery to be carried out. This surgery is aimed at repairing the spleen, a part of it might be removed during surgery. Human beings can live without this organbut they would be more open to several infections.

Enlarged Spleen

Another name for a spleen that is enlarged is splenomegaly. This is a severe but treatable condition. Those with this condition are prone to future ruptures.
