lymph

  (lĭmf) pronunciation
n.
  1. A clear, watery, sometimes faintly yellowish fluid derived from body tissues that contains white blood cells and circulates throughout the lymphatic system, returning to the venous bloodstream through the thoracic duct. Lymph acts to remove bacteria and certain proteins from the tissues, transport fat from the small intestine, and supply mature lymphocytes to the blood.
  2. Archaic. A spring or stream of pure, clear water.

[Latin lympha, water nymph, from Greek numphē, young bride, water nymph.]


 
 

Pale fluid that bathes tissues, maintaining fluid balance and removing bacteria. It enters the blood system at a vein under the collarbone that it reaches via channels and ducts, being driven through them mainly by surrounding muscle activity. The lymphatic organs (spleen and thymus) and lymph nodes filter out bacteria and other particles the lymph takes up from body tissues. Lymph contains lymphocytes and macrophages, the primary cells of the immune system. See also lymphatic system.

(limf)

A clear, colorless fluid that circulates through the lymphatic system. Lymph fills the tissue spaces of the body.

 

A transparent, usually slightly yellow, often opalescent liquid found within the lymphatic vessels, and collected from tissues in most parts of the body and returned to the blood via the lymphatic system. It is about 95% water; the remainder consists of plasma proteins and other chemical substances contained in the blood plasma, but in a slightly smaller percentage than in plasma. Its cellular component consists chiefly of lymphocytes.

  • l. duct — large vessels carrying lymph from smaller collecting vessels. Include thoracic duct, right lymphatic duct.
  • l. heart — a muscular dilatation in a lymph vessel, capable of contraction and moving lymph along the vessel. Seen in embryos and lower vertebrates.
  • l. node — any of the accumulations of lymphoid tissue organized as definite lymphoid organs along the course of lymphatic vessels, consisting of an outer cortical and an inner medullary part; they are the main source of lymphocytes of the peripheral blood and, as part of the reticuloendothelial system, serve as a defense mechanism by removing noxious agents, e.g. bacteria and toxins, and play a critical role in antibody formation. Sometimes called, incorrectly, lymph glands.
  • l. node abscess — hard, usually cold swellings containing pus; secondary to primary lesion in node's drainage area; a feature of some chronic infections, e.g. tuberculosis, caseous lymphadenitis of sheep; specific nodes may cause specific syndromes, e.g. retropharyngeal nodes.
  • l. node hyperplasia — increase in size due to increase in number of normal cells but with preservation of natal architecture.
  • l. node hypoplasia — occurs in cattle and causes antenatal edema of the fetus, leading to dystocia in many cases. The calves are not viable.
  • l. nodule — germinal centers in lymph nodes which produce lymphocytes. Called also lymphatic or lymphoid nodule.
  • periarteriolar l. sheath (PALS) — the white pulp, heavily populated with T lymphocytes, that surrounds arteries in the spleen.
  • l. tissue — see lymphoid tissue.
