What is the spleen and its function in the human body? The spleen is a member of the circulatory system, characterized by its dark red color, as well as by the touch of a thin sponge, and it is responsible for the production of white blood cells that fight infections caused by diseases, as it stores platelets and filters blood, It follows that it is a very important part of the immune system and fighting diseases, and the spleen is an important organ involved in cleaning old blood cells and helps to raise the immune response, although it is relatively small, it performs a variety of roles, despite this, If it is removed, the person can continue without it, and you can follow cultural facts to learn about what the spleen is and its function in the human body.

What is the spleen and its function in the human body?

The spleen is located in the upper left part of the abdomen, behind the stomach, under the diaphragm and the last rib, and the width of the spleen ranges between 8 and 10 cm, when its length ranges between 11 cm and 14 cm, and this makes it a rectangular organ. The weight of the spleen ranges from 150 grams to 200 grams. To remember the size of the spleen is the base 1x3x5x7x9x11

An adult’s spleen measures about 1 inch by 3 inches by 5 inches. It weighs about 7 ounces. It is located between the ninth and eleventh ribs.

The importance of the spleen:

1- The spleen eliminates all microbes, infections, and foreign bodies inside the human body.

2- It helps maintain the immune system because it contains clots from white blood cells, called lymphocytes, which produce antibodies or what are known as “proteins in the blood” that eliminate bacteria.

3- The spleen stores a quarter of the blood in the human body, and it empties into the blood circulation in the event of an injury to the individual.

4- The spleen destroys dead RBCs.

5- It is responsible for regulating the amount of blood that passes through the blood vessels, in addition to purifying the blood from impurities, microbes and viruses in the blood.

Diseases affecting the spleen:

1- Splenomegaly

Enlarged liver disease is caused by leukemia, liver disease, or a viral cause.

2- Sickle cell disease

It is considered a type of anemia as a result of heredity, which results in the coalition of many organs, including the spleen, and the result of this disease is to prevent blood from flowing into the blood vessels.

3- Ruptured spleen disease

The rupture of the spleen is caused by injury, and a rupture of the spleen may cause very dangerous internal bleeding, as the spleen is one of the organs that is threatened with rupture, and this rupture or symptoms may not appear until several weeks after the injury.

Low platelet count disease

Sometimes large amounts of platelets are present, which results in too few platelets in the bloodstream.

Spleen cancer

Cancers that originate in the spleen are relatively rare when they do occur, they are called lymphomas, and leukemia is that which occurs in the lymph system. Lymphomas usually begin in other areas and invade the spleen, according to the National Cancer Institute, this type of splenic invasion can also occur with cancer. Blood, a blood cancer that rarely originates in the bone marrow, other types of cancers – such as lung cancer or stomach cancer – will invade the spleen.

Symptoms of spleen cancer may resemble a cold or there may be pain or fullness in the upper abdomen. An enlarged spleen could also be a result of splenic cancer, and treatment for spleen cancer depends on the type of cancer and how far it has spread. The National Cancer Institute lists spleen removal as a possible treatment.

Spleen disease treatment methods

The treatment methods for the spleen differ according to the type of disease, and the treatment methods are:

Splenectomy

The spleen is removed by surgery, either through laparoscopy (multiple small incisions) or laparotomy (one large incision).

Vaccinations

After splenectomy, it is important to get vaccinations against certain bacteria, such as influenza H. and pneumonia. Absent spleen increases susceptibility to these infections. Typically, treatments for cases of the spleen do not focus on the spleen, but rather on treating the underlying condition.

Causes that require removal of the spleen:

1- Genetic conditions

There are many hereditary diseases that may require removing the spleen, including thalassemia and sickle cell disease.

2- Cancer

This disease may lead to the removal of the spleen not for therapeutic purposes, as it includes treating cancer cells that fight infections, including lymphoma and certain types of leukemia (blood cancer).

3- Other reasons

Sometimes the spleen may become infected with an infection, virus, or bacteria that affects the spleen and cannot be cured until it is removed, or the blood supply to it may be cut off, or an artery of its own may expand abnormally, which leads to its enlargement and then its removal.

The importance of the spleen

The importance of the spleen Although their spleen may be removed, they will be more susceptible than others to infection, viruses, and bacteria, and although the spleen has many functions, it is not an essential organ for life, if it is removed or it does not work efficiently As before, there are other organs that take its place, such as the bone marrow and the liver.

There are symptoms, if they occur after the resection, you must contact the doctor immediately:

1- The wound produces pus 2- Severe pain that is not relieved by medication 3- Chills 4- Excessive flatulence 5- Excessive nausea or vomiting.

Spleen tests and examinations

Physical examination

By pressing the abdomen under the left rib cage, the doctor can feel an enlarged spleen, and he or she can also look for other signs of diseases that cause the enlarged spleen.

Computerized tomography (CT scan):

A CT scan machine takes multiple x-ray images, and a computer creates detailed images of your abdomen. A contrast dye can be injected into your veins to improve the images.

Ultrasound:

A probe is placed on the abdomen, and harmless sound waves produce images. By reflecting the spleen and other organs, an enlarged spleen can be detected by ultrasound.

Magnetic resonance imaging (MRI):

Magnetic waves produce very detailed images of the abdomen. Using a contrast dye, blood flow to the spleen can also be measured using an MRI.

Bone marrow biopsy

A needle is inserted into a large bone (such as the pelvis) and a sample is taken from the bone marrow. Leukemia or lymphomas, which cause the spleen to enlarge, are sometimes diagnosed by a bone marrow biopsy.

Liver and spleen scan:

A small amount of radioactive dye is injected into the arm, and the dye travels throughout the body and is collected in each of these organs.

This was a brief description of what the spleen is and its function in the human body , and we learned that it is a small organ, usually located on the left side of the body, behind the rib cage and stomach, and it is the largest organ in the body’s lymphatic system, which is responsible for enhancing immune function, blood filtering and volume management Blood, the spleen performs many beneficial functions for the body, including making antibodies, removing bacteria, removing old red blood cells, breaking down waste from red blood cells, recycling iron for use in new red blood cells, and holding back up red blood cells. , And immune cells that the body can use in emergency situations.
