Lymph: From 4 Different Sources


A watery or milky body fluid containing lymphocytes, proteins, and fats.

Lymph accumulates outside the blood vessels in the intercellular spaces of body tissues, and is collected by the vessels of the lymphatic system.

This system filters the fluid and eventually returns it to the bloodstream.

Lymph plays an important role in the immune system as well as in absorbing fats from the intestine.

Pertaining to the lymph system or lymph tissue, the “back alley” of blood circulation. Lymph is the alkaline, clear intercellular fluid that drains from the blood capillaries, where the arterial blood separates into thick, gooey venous blood and lymph. It bathes the cells, drains up into the lymph capillaries, through the lymph nodes for cleaning and checking against antibody templates, up through the body, and back to recombine with the venous blood in the upper chest. Blood in the veins is thick, mainly because part of its fluid is missing, traveling through the tissues as lymph. Lymph nodes in the small intestine absorb most of the dietary fats as well-organized chylomicrons. Lymph nodes and tissue in the spleen, thymus, and tonsils also organize lymphocytes and maintain the software memory of previously encountered antigens and their antibody defense response. Blood feeds the lymph, lymph feeds the cells, lymph cleanses the cells and returns to the blood.

Lymph is the ?uid which circulates in the lymphatic vessels of the body. It is a colourless ?uid, like blood PLASMA in composition, only rather more watery. It contains salts similar to those of blood plasma, and the same proteins, although in smaller amount: FIBRINOGEN, serum albumin (see ALBUMINS), and serum GLOBULIN. It also contains lymphocytes (white blood cells), derived from the glands. In some lymphatic vessels, the lymph contains, after meals, a great amount of FAT in the form of a ?ne milky emulsion. These are the vessels which absorb fat from the food passing down the INTESTINE, and convey it to the thoracic duct; they are called lacteals because their contents look milky (see CHYLE).

The lymph is derived, initially, from the blood, the watery constituents of which exude through the walls of the CAPILLARIES into the tissues, conveying material for the nourishment of the tissues and absorbing waste products.

The spaces in the tissues communicate with lymph capillaries, which have a structure similar to that of the capillaries of the blood-vessel system, being composed of delicate ?at cells joined edge to edge. These unite to form ?ne vessels, resembling minute veins in structure, called lymphatics, which ramify throughout the body, passing through lymphatic glands and ultimately discharging their contents into the jugular veins in the root of the neck. Other lymph vessels commence in great numbers as minute openings on the surface of the PLEURA and PERITONEUM, and act as drains for these otherwise closed cavities. When ?uid is e?used into these cavities – as in a pleural e?usion, for example – its absorption takes place through the lymphatic vessels. The course of these vessels is described under the entry on GLAND.

Lymph circulates partly by reason of the pressure at which it is driven through the walls of the blood capillaries, but mainly in consequence of incidental forces. The lymph capillaries and vessels are copiously provided with valves, which prevent any back ?ow of lymph, and every time these vessels are squeezed (as by the contraction of a muscle, or movement of a limb) the lymph is pumped along.

The term lymph is also applied to the serous ?uid contained in the vesicles which develop as the result of vaccination, and used for the purpose of vaccinating other individuals.

Lymphoma

A neoplasia of the lymph tissue, such as Hodgkin’s Disease. Although it is frequently useful to stimulate immunity when a person is undergoing chemotherapy for cancer, since the resultant immunosuppression is a major side effect of the treatment, in lymphatic cancer this the POINT of the therapy...let it be.... lymphoma

Lymphadenitis

Inflammation or swelling of one or more lymph nodes. It may be an acute response or chronic, but signals the drainage into those nodes of microbes, their waste products, or the immuno-complexes produced upstream, whether from infection or allergy. A few infections can target or inhabit lymph nodes such as typhoid and EBV. Some people, with a past history of infection in a specific tissue (such as chronic sore throat as a kid) will have developed a LARGER sized node, hard and permanently palpable. These are hypertrophic or “shotty” nodes, and of no more importance than pumped-up muscles or old scar tissue.... lymphadenitis

Lymphadenopathy

Lymphocyte

A variety of white blood cell produced in the LYMPHOID TISSUE and lymphatic glands (see LYMPHATICS; GLAND) of the body. It contains a simple, rounded nucleus surrounded by protoplasm generally described as non-granular. Two varieties of lymphocyte are described, small and large, and together they form over 20 per cent of the white cells of the blood. They play an important part in the production of ANTIBODIES, and in the rejection of transplanted organs such as the heart (see TRANSPLANTATION). This they do in two di?erent ways: what are known as B-lymphocytes produce antibodies, while T-lymphocytes attack and destroy antigens (see ANTIGEN) directly. The latter are known as T-lymphocytes because they are produced by the THYMUS GLAND. Their numbers are increased in TUBERCULOSIS and certain other diseases. Such an increase is known as LYMPHOCYTOSIS.... lymphocyte

Lymphatic System

Lymph is the same fluid which oozes from a cut when bleeding stops. It surrounds every living cell. Lymph conveys to the blood the final products of digestion of food. It also receives from the blood waste products of metabolism. This is a two-way traffic.

Lymph fluid, loaded with waste, excess protein, etc, is sucked into the lymph tubes to be filtered by the spleen and the lymph nodes. The tubes are filled with countless one-way valves referred to collectively as the lymphatic pump, which propels the flow of lymph forwards. Lymph ultimately is collected in the main thoracic duct rising upwards in front of the spine to enter the bloodstream at the base of the neck.

A number of disorders may arise when the fluid becomes over-burdened by toxaemia, poor drainage and enlarged nodes (glands). Such un-eliminated wastes form cellulite – unwanted tissue formation and swelling. Thus, the soil may be prepared for various chronic illnesses from glandular disorders to arthritis. If the lymph is circulating freely it is almost impossible to become sick.

This system is capable of ingesting foreign particles and building up an immunity against future infection. Some herbal Lymphatics are also antimicrobials, natural alternatives to conventional antibiotics.

Burkitt’s Lymphoma

Lymphoid tumour associated with Epstein-Barr (EB) virus. Especially common in malaria endemic areas, such as Africa and Papua New Guinea. May be associated with the immunosuppressive effects of the malaria infection.... burkitt’s lymphoma

Lymph Nodes

The central drainage and metabolic organs strung along the lymph vessels. The mesenchymal structure is native, being present at birth. The functional cells have all migrated there, some recently from the marrow, spleen, thymus or blood, others have resided since a few months after birth. Much of the antibody memory is stored in these nodes, and having only venous blood supply, lymph nodes are constantly shunting metabolized substances back into the blood, so the final lymph drainage from the thoracic duct into the left subclavian vein (or the right subclavian) contains fluid already screened and cleansed by many nodes.... lymph nodes

Lymphadenectomy

Surgical removal of the LYMPH NODES. The procedure is usually carried out when cancer has in?ltrated the nodes in the lymphatic drainage zone of an organ or tissue invaded by a malignant growth.

Burkitt’s Lymphoma

A cancer of lymph tissues that is characterized by tumours within the jaw and/or abdomen. It is confined almost exclusively to children living in low-lying, moist, tropical regions of Africa and New Guinea. Anticancer drugs or radiotherapy give complete or partial cure in about 80 per cent of cases. (See also lymphoma.)... burkitt’s lymphoma

Lymph Node

A small organ lying along the course of a lymphatic vessel (see lymphatic system); commonly but incorrectly called a lymph gland. Lymph nodes vary considerably in size, from microscopic to about 2.5 cm (1 in) in diameter.

A lymph node consists of a thin, fibrous outer capsule and an inner mass of lymphoid tissue. Penetrating the capsule are several small lymphatic vessels (whichcarry lymph into the node). Each node contains sinuses (spaces), in which the lymph is filtered. The flow of the lymph slows as it moves through narrow channels in the sinuses; this reduction in flow allows macrophages (white blood cells that engulf and destroy foreign and dead material) time to filter microorganisms from the lymph. Germinal centres in the lymph node release white blood cells called lymphocytes, which also help to fight infection. A single, larger vessel carries lymph out of the node.... lymph node

B-lymphocyte (or B-cell)

A type of white blood cell that circulates through the body and is able to detect the presence of the foreign agents. Once exposed to an antigen on the agent, these cells differentiate into plasma cells to produce antibody.... b-lymphocyte (or b-cell)

Cleavers Tea - Best Tonic For The Lymphatic System Available In Nature

Cleavers tea has been used for centuries, even in ancient Greece. It is considered probably the best tonic for the lymphatic system available. Discover all of its benefits and learn how to make the most of this type of tea. Description of Cleavers tea Cleavers is an annual green plant that grows mostly in Britain, North America and Eurasia regions. The green to white flowers look like small balls and they are very sticky, similar to the leaves. Scientifically named gallium aparine, cleavers is also called bedstraw, barweed, catchweed, grip grass. The entire cleavers plant is used in herbal medicine and is harvested just before it blooms in early summer. The active constituents of cleavers tea are chlorophyll, citric acide, rubichloric acid, galiosin and tannins. To benefit the most from these constituents, you can consume cleavers, usually found in the form of tea, extracts, capsule, or fresh for many cooking recipes. The roasted seeds are used as a coffee substitute and the young leaves can be eaten like spinach. Cleavers tea has a slightly bitter taste and no odor. Cleavers tea brew For a tasty Cleavers tea, take 2 to 3 teaspoons of the dried above-ground parts of the plant and infuse them in a 250 mg cup of hot water for 10 or 15 minutes. You may add sugar or honey to improve its taste and drink up to three times per day. Cleavers tea  Benefits Cleavers tea is a strong detoxifying for the lymphatic system. It is diuretic, thus treating most of urinary tract infections. It cleans the blood, the liver and kidneys. The tea can be used together with Uva Ursi or Echinacea for best results. Applied topically, Cleavers tea helps in the treatment of many skin conditions like acne, eczema, psoriasis, dandruff, itchy scalp, sunburns or even wounds. Cleavers tea can be used as a facial tonner because it helps clear the complexion. Cleavers tea Side effects Cleavers tea has no known side effects. Though it is widely safe, children, pregnant or nursing women should drink it with precaution. Cleavers tea can surely be included in a healthy lifestyle. As long as you don’t exaggerate with it, you can enjoy the benefits of this tea and even use the plant to prepare many tasty recipes and salads.... cleavers tea - best tonic for the lymphatic system available in nature

Leukaemia, Chronic Lymphocytic

A type of leukaemia caused by proliferation of mature lymphocytes. Although it is incurable, the disease is not always fatal. The cause is unknown.

Symptoms develop slowly, often over many years. As well as symptoms and signs common to acute forms of leukaemia (see leukaemia, acute), there may be enlargement of the liver and spleen, persistent raised temperature, and night sweats. Diagnosis is by blood tests and a bone marrow biopsy. In many mild cases, no treatment is needed. To treat severe cases, anticancer drugs are given, sometimes with radiotherapy.... leukaemia, chronic lymphocytic

Lymphoma, Non-hodgkin’s

Any cancer of lymphoid tissue (found mainly in the lymph nodes and spleen) other than Hodgkin’s disease. In most cases there is no known cause. Occasionally, the disease is associated with suppression of the immune system, particularly after an organ transplant. One type of nonHodgkin’s lymphoma, known as Burkitt’s lymphoma, is thought to be caused by the Epstein–Barr virus.

There is usually painless swelling of lymph nodes in the neck or groin. The liver and spleen may enlarge, and lymphoid tissue in the abdomen may be affected. Many other organs may become involved, leading to diverse symptoms ranging from headache to skin ulceration. Unless it is controlled, the disease (often marked by fever) progressively impairs the immune system, leading to death from infections or an uncontrolled spread of cancer. Diagnosis is based on a biopsy, usually taken from a lymph node. Chest X-ray, CT scanning, MRI, bone marrow biopsy, and lymphangiography of the abdomen may be needed to assess the extent of the disease.

If the lymphoma is confined to a single group of lymph nodes, treatment consists of radiotherapy. More often, the disease is more extensive, and in such cases anticancer drugs are given. A bone marrow transplant, together with drug treatment and/or radiotherapy, may be performed on some people.... lymphoma, non-hodgkin’s

Sentinel Lymph Node

the first lymph node to show evidence of metastasis (spread) of a malignant tumour (e.g. breast cancer) via the lymphatic system. Absence of cancer cells in the sentinel node indicates that more distal lymph nodes will also be free of metastasis. In breast cancer, the change in practice to perform axillary lymph node dissection only if the sentinel node contains metastatic tumour has reduced the risk of arm lymphoedema. Similarly, in head and neck squamous cell carcinomas, the sentinel lymph node procedure is used as an alternative to neck dissection.... sentinel lymph node
