The spleen is an organ located above your stomach and below your ribs on your left side. It looks like your fist. The spleen is part of your lymphatic system, which fights infection and keeps your body fluids in balance. It contains white blood cells that fight germs. Your spleen also helps control the amount of blood in your body, and destroys old and damaged cells.

What Is The Purpose Of Spleen In Human Body

Some diseases can make your heart swell. You can also damage or break your heart from an injury, especially if it is already swollen. If your heart is too damaged, you may need surgery to remove it. You can live without a spleen. Other organs, such as your liver, will take over some of the spleen’s functions. Without a spleen, however, your body cannot fight disease.

Although most people do not know about the spleen, it remains an important organ in the abdomen that performs many functions. Behind the stomach on the upper left side of the abdomen, the spleen is a fist-sized organ that is part of the lymphatic system, which is part of the immune system. The role of the spleen is to act as a filter for our blood to remove old blood cells and detect pathogens that may have entered the body.

The spleen is in the left upper quadrant of the abdominal cavity below the diaphragm and behind the ribs; it is located between the stomach, kidneys and pancreas. The spleen is surrounded by a capsule of connective tissue that is held in place by various ligaments. Because of its important role as a blood vessel, the spleen is also highly vascularized with blood supply from the arteries. It is also a relatively small organ, usually 3 to 5 inches long for most adults.

Unlike many other organs, the spleen does not have easily distinguishable regions or divisions. Instead, it consists of two different types of fat that are mixed throughout: red pulp and white pulp. The white pulp is lymphoid tissue that surrounds many blood vessels and contains plasma cells, lymphocytes and lymphatic nodules. The red pulp contains a network of splenic tissues and sinusoids and acts as a reservoir for a type of white blood cell called monocytes.

As noted, the spleen has many functions depending on the type of cells it contains. The white pulp, which accounts for 25% of the fat in the spleen, is primarily involved in the normal immune response to potential infections. When a pathogen is detected, lymphocytes stored in the spleen are activated and produce antibodies. These antibodies circulate through the lymphatic system to find and attack the pathogen. The white pulp of the spleen is the source of antibodies in the body.

The other 75% of splenic tissue is red pulp, and most of it is involved in filtering blood in a similar way to filtering lymph fluid. One of the most important jobs is to remove old, damaged red blood cells from circulation so that new, healthy cells can replace them. In addition to filtering the blood for old blood cells and certain types of bacteria, the spleen also acts as a reservoir for platelets and red blood cells that can be released into the bloodstream in the event of an injury that causes blood loss. .

Technically, the spleen is not considered a “vital” organ because people can still live a normal life after it is removed. But because of its role in regular immune function, the absence of the spleen can increase the risk of illness and disease. Fortunately, the spleen rarely needs to be removed, although there are a number of problems that can affect the organ:

Considering the number of potential problems that can negatively affect the spleen, it is surprising that treatment options are limited. Generally, spleen problems will be resolved by treating the underlying condition. For example, cases of sickle cell anemia can be treated with medication, lifestyle changes, or in rare cases with a bone marrow transplant. In cases of infection or asplenia, antibiotics or vaccines are usually used.

For all spleen problems that cannot be treated with medication and therapy, the usual procedure is surgery. Splenectomy surgery is usually performed laparoscopy to limit the complications and risks of surgery. Depending on the nature of the problem, part or all of the spleen is removed during surgery. With some lifestyle changes, most people can continue to live a normal life after surgery.

Because of the spleen’s importance in blood filtration and immune function, living without a person requires some adjustments. Fortunately, other organs such as the liver can take over some of these functions, but the patient will still be susceptible to certain diseases such as pneumonia or meningitis. The biggest disadvantage is that the increased risk will remain throughout a person’s life.

To minimize the risk of infection, most splenectomy patients must take low-dose antibiotics regularly, especially for the first two years after surgery. People who have had their spleens removed also need to make sure they are up to date on all vaccinations. They also need to be especially alert for symptoms such as fever and cough.

The spleen is an important organ of the lymphatic system, but there are some ways in which its function is related to the digestive system. Although there are less obvious symptoms related to spleen problems, it is always good to know the changes in your body. If you’re experiencing unusual symptoms and aren’t sure what they could mean, it’s a good idea to seek advice from an expert like the very knowledgeable staff at Cary Gastro.

Removes unhealthy, old, and dysfunctional red blood cells from circulation.Nerthuz/iStock/Thinkstock

The spleen helps keep harmful microorganisms out of the blood. It contains the main components of the body’s immune system. The spleen also removes unhealthy, old, and poorly formed red blood cells from circulation.

Red blood cells carry oxygen throughout the body and remove carbon dioxide (waste products). These disc-shaped cells are filtered by the spleen according to their physiological properties. They can only enter the blood vessels if they can pass through a tiny structure called the interendothelial slit. When red blood cells change in size, shape, or ability to turn, they cannot pass.

In some cases, such as hereditary spherocytosis, the wrong red blood cells can become trapped in the spleen, causing anemia. In addition, certain diseases – such as malaria, leukemia, and lymphoma – can cause the spleen to enlarge and cause it to filter out not only abnormal cells but also healthy red blood cells.

It is difficult to study how the spleen filters out the wrong red blood cells. The anatomy and physiology of the human spleen differs from that of conventional laboratory animal models. And invasive procedures, such as a biopsy or a needle, can cause dangerous bleeding. A research team led by Dr. Subra Suresh of Carnegie Mellon University and Dr. Ming Dao of MIT approached the problem using computational simulation tools. Their work was funded by the National Heart, Lung, and Blood Institute (NHLBI). The study was published online

The team developed computational simulations of the mechanics of red blood cells as they pass through the spleen. The researchers determined that the cells are significantly damaged when they pass through the narrow slit. On the contrary, according to them, the simple bullet-shaped changes that occur in narrow capillaries.

The analysis showed the limits of the surface area and the amount of red blood cells that can cross the spleen. The work showed how the splenic cyst determines the size and distribution of healthy red blood cells. The team’s predictions were consistent with the results of independent experiments using healthy, artificially modified and infected red blood cells.

“Computational modeling and analysis from this work, together with various experimental observations, indicate a more detailed picture of how the physiology of the human spleen may be affected.
