It is made up of a complex network of lymphoid organs, lymph nodes, lymph ducts, lymph tissues, lymph capillaries and a network of lymphatic vessels that carry lymph and other substances throughout the body. In comparison to the cardiovascular system the lymphatic system has not in the past been the focus of much research. The spleen, which is located in the upper left part of the abdomen under the ribcage, works as part of the lymphatic system to protect the body, clearing worn out red blood cells and other foreign bodies from the bloodstream to help fight off infection.
The lymphatic system collects this fluid and returns it to the circulatory system. The lymphatic system plays an integral role in the immune functions of the body.
It is the first line of defense against disease. This network of vessels and nodes transports and filters lymph fluid containing antibodies and lymphocytes good and bacteria bad. The spleen also helps the body fight infection. The spleen contains lymphocytes and another kind of white blood cell called macrophages, which engulf and destroy bacteria, dead tissue, and foreign matter and remove them from the blood passing through the spleen.
Lymph vessels in the lining of the gastrointestinal tract absorb fats from food. A malfunction of this part of the lymphatic system can result in serious malnutrition. The lymphatic system also impacts diseases such as excessive obesity caused by abnormal fat and carbohydrate metabolism. 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 heart, lungs, intestines, liver, and skin also contain lymphatic tissue. The lymphatic system has three primary functions. First of all, it returns excess interstitial fluid to the blood. Of the fluid that leaves the capillary , about 90 percent is returned. The 10 percent that does not return becomes part of the interstitial fluid that surrounds the tissue cells. Small protein molecules may "leak" through the capillary wall and increase the osmotic pressure of the interstitial fluid.
Different approaches include: 1 cancer vaccination to train the immune system to recognise the cancer cells as targets to be destroyed, 2 giving therapeutic antibodies to recruit immune system cells to destroy tumor cells, and 3 cell based immunotherapy which is either transfusing immune cells such as Natural killer Cells or by administering cytokines such as Interleukins which activate the immune cells.
There are over different sub-types of HPV. Over time these can cause cells in the cervix to change, leading to precancerous conditions - cervical intraepithelial neoplasia CIN , with a higher risk of developing cancer. It can have many causes. In the context of cancer it is often a result of obstruction by a tumor or enlarged lymph nodes.
It can also be a side effect of radiotherapy or surgery, which has damaged the lymph vessels. Here are some examples related to the Lymphatic and Immune systems.
Immune System. Introduction to the Lymphatic System. Lymphatic System - Self Test questions. WebAnatomy, University of Minnesota Test your anatomy knowledge with these interactive questions. Includes different question types and answers. Mechanism of lymph node metastasis in prostate cancer.
Future Oncol. Sentinel Lymph Node Biopsy. National Cancer Institute Factsheet in the form of questions and answers, with references. The components of the immune system. New York: Garland Science; The Immune System. Paul Andersen Paul Andersen explains how your body protects itself from invading viruses and bacteria. He starts by describing the nonspecific immune responses of skin and inflammation.
He then explains how we use antibodies to disrupt the function of antigens and mark them for destruction. He then explains both the homoral and cell-mediated immune response highlighting the importance of B and T lymphocytes. He finally describes the process of long term immunity. The Lymphatic System. UCSF Dr. Found this page useful? Introduction What is Cancer? Lymph Lymph is a fluid that circulates throughout the body in the lymphatic system.
It contains a high number of lymphocytes white cells that fight infection.
