Organs that can remove us and continue living

A organ is defined as a functional unit of the organism. It is formed by a more or less complex grouping of tissues and cells specialized in a certain function.

All organ functions are important, but some are vital. Without that function the body dies.

However, it is surprising how many organs that we can lose and continue living with an acceptable quality of life, even without any type of problem.

Among the organs that can be removed and continue living we have the spleen, the stomach, reproductive organs, a lung, a kidney, the colon, the appendix or the gallbladder.


The spleen is an organ of lymphatic system very important in the activity of the immune system, both in humoral immunity and in cellular immunity.

This is also where old red blood cells are destroyed and some components of the blood, notably iron and hemoglobin, are recycled.

Due to its location, under the ribs and above the stomach on the left side of the abdomen, it is relatively unprotected. Trauma is the most common cause of spleen removal.

Surprisingly the spleen can be removed if necessary and not be life threatening. The liver takes the role in the recycling of red blood cells and other lymphoid tissues take on the immune function.


The stomach It is an organ that is part of the digestive tube. Your contractions and secretions help digest foodThey are necessary to absorb some vitamins and also act as a defense mechanism by destroying bacteria and other types of pathogens.

The stomach is removed for various reasons, including cancer. The gastrectomy It may be partial or total. If the entire stomach is removed, the esophagus joins directly to the duodenum, the first portion of the small intestine.

After removal, the person receives nutrients intravenously for a period of time. When you fully recover you will be able to eat a fairly normal diet, although you will need to eat small portions and chew very well, or eat semi-solid foods.

People without a stomach also often need supplements of some vitamins and minerals.

reproductive organs

The uterus, ovaries or testicles are organs that are removed for various reasons, including cancer and trauma.

Women and men are a single ovary or a single testicle can still have offspring. If both are removed, in addition to ceasing to be fertile, symptoms may develop due to hormonal changes.


Every person has two lungs. Although the capacity for physical exertion may be limited, it is possible to do without a part of a lung or an entire lung and lead a normal life.

The most common reason for removing a lung is cancer.


The kidneys they filter our blood to remove chemical waste products. From this filtration urine is formed.

There are several reasons for removing a person's kidneys. Among them are hereditary diseases, pyelonephritis, drug and alcohol damage, cancer, etc.

As with the lungs, each person has two kidneys and can survive with only one. It is even possible to live without any kidneys, although in this case a hemodialysis periodic and has many negative effects.


The colon It is the largest part of the large intestine and among its functions is the reabsorption of water from the food bolus and its transformation into feces.

The colon cancer and its prevention, along with Crohn's disease, are the most common causes of colon removal.

People can live without a colon by carrying a bag outside the body that collects feces and remains of the food bolus. In some cases, an internal bag can also be placed in the small intestine that acts as a colon.


The gallbladder, located under the liver, is responsible for storing and maturing bile. Bile is necessary for the digestion of fats, but too much cholesterol can cause the formation of gallstones (cholelithiasis).

In some cases of cholelithiasis, removal of the gallbladder may be necessary. The operation is known as cholecystectomy.

The removal of this organ can be supplemented with a low-fat diet and, on some occasions, with a nutritional supplement or a special diet.


The appendix It is a small dead-end tube attached to the intestinal cecum, the first part of the large intestine. The function of the appendix is ​​not very clear and it is often considered a vestigial organ, although it has been proven that it acts as a reservoir of microorganisms of the intestinal flora.

Because it has no outlet, contents of the intestine can sometimes enter and then cannot come out. This can cause inflammation of the appendix (appendicitis) and in severe cases it may be necessary to remove it.
