Immune And Lymphatic Systems.

LYMPHATIC SYSTEM. The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste and other unwanted materials..

DISEASES AND DISORDERS. Diseases and disorders of the lymphatic system are typically treated by immunologists. The most common diseases of the lymphatic system are enlargement of the lymph nodes (also known as lymphadenopathy), swelling due to lymph node blockage (also known as lymphedema) and cancers involving the lymphatic system.

Lymphoma This refers to cancer of the lymph nodes. It occurs when lymphocytes grow and multiply uncontrollably. The most common types of NHL are follicular, which accounts for about 30% of all NHL cases; diffuse large B-cell lymphoma (DLBCL), which comprises 40 to 50% of NHL cases; and Burkitt's lymphoma, which accounts for 5% of NHL cases..

Lymphatic filariasis Considered a neglected tropical disease (NTD), this parasitic disease is caused by the infiltration of a thread-like worm that infects the lymphatic system, according to the Centers for Disease Control and Prevention (CDC)..

What can go wrong with your immune system? When your immune system doesn't work the way it should, it is called an immune system disorder. You may: Be born with a weak immune system. This is called primary immune deficiency. Get a disease that weakens your immune system. This is called acquired immune deficiency. Have an immune system that is too active. This may happen with an allergic reaction. Have an immune system that turns against you. This is called autoimmune disease..

Some conditions caused by an overactive immune system are: Asthma. The response in your lungs can cause coughing, wheezing, and trouble breathing. Asthma can be triggered by common allergens like dust or pollen or by an irritant like tobacco smoke. Eczema. An allergen causes an itchy rash known as atopic dermatitis. Allergic rhinitis. Sneezing, a runny nose, sniffling, and swelling of your nasal passages from indoor allergens like dust and pets or outdoor allergens like pollens or molds..

In autoimmune diseases, the body attacks normal, healthy tissues. The cause is unknown. It is probably a combination of a person’s genes and something in the environment that triggers those genes..

Rheumatoid arthritis . This type of arthritis causes swelling and deformities of the joints. An auto-antibody called rheumatoid factor is in the blood of some people with rheumatoid arthritis..
