There is no one specific organ that takes over the functions of the spleen, rather their are several tissues in the body that are able to pick up some of the important functions of the spleen, for example the recycling of red blood cells.
Yes that is true, but, once the spleen is gone, the liver takes over most of the fuctions that the spleen used to do.
One of the functions of the spleen is to play a role in the processing of dead red blood cells (erythrocytes), but it is not the only place in the body where that process takes place. The liver can take up that function as well as other tissues in the lymphatic system.
Some of the jobs of the spleen are taken over by the liver, but not all. The spleen stores platelets for instance. This job is not done by anything after the spleen is removed, but this is really not too big of a deal. The spleen also takes apart red blood cells after they are dead and can reuse the material taken from them (This process also creates bilirubin which is taken by the liver and is an ingredient of bile, the substance stored in your gallbladder and used in digestion). The spleen is also part of your lymphatic and immune system, so there are some jobs that go undone. There are meds that patients of spleen removal must take for the rest of their life after a splenectomy.
After the removal of the spleen, the liver and bone marrow take over its functions.
The two organs that produce red blood cells prior to birth are the liver and the spleen. After birth, the bone marrow takes over as the primary site of red blood cell production.
Yes. But it takes time and effort. You can't wrestle or do any contact sports... Baseball, basketball, horseback riding, etc. You know your spleen is swollen if your ribs are or have been hurting. Also tell your doctor because an enlarged spleen could mean lots of things such as infections. They might need to take blood of do an ultrasound.
After birth, the two organs that take over the placenta's functions are the lungs and the liver. The lungs begin to facilitate gas exchange, allowing the baby to breathe air and obtain oxygen. Meanwhile, the liver takes on functions related to metabolism and detoxification, processing nutrients from breast milk or formula. Together, these organs support the baby's physiological needs as they transition to life outside the womb.
The Liver.
The organs of the circulatory system include the heart, blood, and blood vessels. The heart is the pump that takes the oxygenated blood through the blood vessels to supply the cells with energy.
A spleen disorder is quite dangerous as it takes away the immunity of the person which then makes them very vulnerable to infection and means that they will have to take special medications for the rest of their lives to accommodate this.
Your lungs
Following removal of the spleen, the liver primarily takes over the role of filtering out the older red blood cells. Other organs may also contribute to red cell removal, eg. heart. However, these other organs cannot completely compensate for the loss of the spleen. Consequently there is an increased risk of infections as well as, over time, iron overload in patients. These consequences have their own dangers. For example, increased liver iron can lead to cirrhosis. Other organs, such as the heart, are also susceptible to accumulation of iron and can ultimately lead to heart failure if iron accumulation is great. Thus splenectomised patients should have their circulating iron levels regularly checked. If the spleen is removed as a treatment for a severe anemia, it is more important that iron levels are thoroughly monitored. Iron supplements (a supposed simple 'fix-all' dietary treatment for anemia) can therefore do more harm than good for such patients.
Most of the cleanup of dead red blood cells takes place in the spleen. The spleen contains specialized cells called macrophages that engulf and break down the old red blood cells, recycling their components for future use in the body.
