News The lymphatic system is part of the immune system. It also maintains fluid balance and plays a role in absorbing fats and fat-soluble nutrients. The lymphatic or lymph system involves an extensive network of vessels that passes through almost all our tissues to allow for the movement of a fluid called lymph.
The primary function of the lymphatic system is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body. The vessels are connected to lymph nodes, where the lymph is filtered. The tonsils, adenoids, spleen and thymus are all part of the lymphatic system.
Description of the lymphatic system There are hundreds of lymph nodes in the human body. They are located deep inside the body, such as around the lungs and heart, or closer to the surface, such as under the arm or groin, according to the American Cancer Society.
The lymph nodes are found from the head to around the knee area.
The spleenwhich is located on the left side of the body just above the Lymphatic system and body, is the largest lymphatic organ, according to the U.
If the spleen detects potentially dangerous bacteria, viruses, or other microorganisms in the blood, it — along with the lymph nodes — creates white blood cells called lymphocytes, which act as defenders against invaders.
The lymphocytes produce antibodies to kill the foreign microorganisms and stop infections from spreading. Humans can live without a spleen, although people who have lost their spleen to disease or injury are more prone to infections.
The lymphatic system helps keep the body healthy by eliminating infections and diseases. This small organ stores immature lymphocytes specialized white blood cells and prepares them to become active T cells, which help destroy infected or cancerous cells.
Tonsils are large clusters of lymphatic cells found in the pharynx. They sample bacteria and viruses that enter the body through the mouth or nose. Lymph is a clear and colorless fluid; the word "lymph" comes from the Latin word lympha, which means "connected to water," according to the National Lymphadema Network.
Most of this fluid returns to the venous circulation through tiny blood vessels called venules and continues as venous blood. The remainder becomes lymph, according to the Mayo Clinic.
Unlike blood, which flows throughout the body in a continue loop, lymph flows in only one direction — upward toward the neck. Lymphatic vessels connect to two subclavian veins, which are located on either sides of the neck near the collarbones, and the fluid re-enters the circulatory system, according to the Mayo Clinic.
Diseases and disorders of the lymphatic system Diseases and disorders of the lymphatic system are typically treated by immunologists. Vascular surgeons, dermatologists, oncologists and physiatrists also get involved in treatment of various lymphatic ailments.
There are also lymphedema therapists who specialize in the manual drainage of the lymphatic system. The most common diseases of the lymphatic system are enlargement of the lymph nodes also known as lymphadenopathyswelling due to lymph node blockage also known as lymphedema and cancers involving the lymphatic system, according to Dr.
James Hamrick, chief of medical oncology and hematology at Kaiser Permanente in Atlanta. When bacteria are recognized in the lymph fluid, the lymph nodes make more infection-fighting white blood cells, which can cause swelling.
The swollen nodes can sometimes be felt in the neck, underarms and groin, according to the NLM. Lymphadenopathy is usually caused by infection, inflammation, or cancer.
Infections that cause lymphadenopathy include bacterial infections such as strep throat, locally infected skin wounds, or viral infections such as mononucleosis or HIV infection, Hamrick stated. In some areas of the body the enlarged lymph nodes are palpable, while others are to deep to feel and can be seen on CT scan or MRI.
This can happen in lupus, according to Hamrick.
Lymphoma is cancer of the lymph nodes. It occurs when lymphocytes grow and multiply uncontrollably. There are a number of different types of lymphoma, according to Dr. Sharman, director of research at Willamette Valley Cancer Institute and medical director of hematology research for the U.
Non-Hodgkin lymphoma is more common of the two, according to the Lymphoma Research Foundation. This most commonly occurs in women who have had surgery to remove a breast cancer. Part of the operation to remove the breast cancer involves removing lymph nodes in the armpit.
The more lymph nodes removed the higher the risk of chronic bothersome swelling and pain due to lymphedema in the arm, Hamrick explained. From the research, they estimated that the risk of developing anaplastic large cell lymphoma in the breast after getting implants is 1 in 35, at age 501 in 12, at age 70, and 1 in 7, at age The study was published in the Jan.
Castleman disease is a group of inflammatory disorders that cause lymph node enlargement and can result in multiple-organ dysfunction, according to the Castleman Disease Cooperative Network.
While not specifically a cancer, it is a similar to a lymphoma and is often treated with chemotherapy. It can be unicentric one lymph node or multicentric, involving multiple lymph nodes.The lymphatic system is a network of very small tubes (or vessels) that drain lymph fluid from all over the body.
The major parts of the lymph tissue are located in the bone marrow, spleen, thymus gland, lymph nodes, and the tonsils. The lymphatic system is a network of very small tubes (vessels) that drain lymph fluid from all over the body.

The lymphatic system removes infections and other toxins from the blood. A sick body is a toxic and infected (or soon to be infected) body. Arguably, most every chronic disease and every infection is indicative of an overwhelmed lymphatic system.
When the system is overwhelmed, the body .
The lymphatic system includes a system of lymphatic capillaries, vessels, nodes, and ducts that collects and transports lymph, which is a clear to slightly yellowish fluid, similar to the plasma in blood. The lymphatic system is important for maintaining your body’s fluid balance, and it helps.
The lymphatic system is crucial to your immunity. It acts as your personal body builder. The Lymphatic System: Why Is It So Powerful?
Marcelle Pick is the founder and nurse practitioner of Women. The lymph system is the body's drainage system. It is composed of a network of vessels and small structures called lymph nodes. The lymph vessels convey excess fluid collected from all over the body back into the blood circulation.
