lymphoid

resembling or pertaining to lymph or to tissue of the lymphatic system.

bronchus-associated lymphoid tissue (BALT)
aggregations of B and T lymphocytes in the lower respiratory tract.
lymphoid cells
lymphocytes and plasma cells.
lymphoid foci
small foci of lymphoid tissue which occur in almost all parenchymatous organs in birds. The foci are not encapsulated and blend with the surrounding tissue.
lymphoid follicles
see lymph nodule.
lymphoid granuloma
one of the lesions in chronic follicular pharyngitis in the horse and a cause of persistent cough, difficulty in swallowing and a stertorous respiration.
gut-associated lymphoid tissue (GALT)
aggregations of mucosal-associated lymphoid tissue in the gastrointestinal tract, including adenoids, tonsils, Peyer's patches and lamina propria of the intestine; responsible for a local immune response to antigens.
lymphoid leukemia
see lymphatic leukemia.
lymphoid leukosis
a very rare primary tumor in mammals characterized by high blood lymphocyte counts. It is the most common form of the avian leukosis complex of diseases caused by avian retroviruses. Birds are affected between the ages of 14 to 30 weeks and show nonspecific signs of emaciation, inappetence and weakness, but many also have enlarged abdomens and a palpably enlarged liver. The primary lesion is the transformation of B lymphocytes in the lymphoid follicles of the bursa of Fabricius, but multiple metastatic lesions occur in the liver, spleen, etc.
mucosal-associated lymphoid tissue (MALT)
aggregations and organized lymphoid cells tissue found immediately beneath mucous membranes lining the respiratory, gastrointestinal and urogenital system.
lymphoid organs
primary lymphoid organs include the thymus and the bursa of Fabricius and its mammalian equivalent; secondary lymphoid organs include lymph nodes, spleen, Peyer's patches, etc.
skin-associated lymphoid tissues
include a group of non-activated T lymphocytes and Langerhans cells derived from lymphatic or hematopoietic tissues which have antigen-presenting properties; enable the skin to maintain a functional immunological relationship with the immune system. Called also SALT.
lymphoid system
the lymphoid tissue of the body, collectively; it consists of the bone marrow, thymus, lymph nodes, spleen, and gut-associated lymphoid tissue (tonsils, Peyer's patches).
lymphoid tissue
a lattice work of reticular tissue, the interspaces of which contain lymphocytes.
lymphoid tumor

lymphatic, lymphoid

1. pertaining to lymph or to a lymphatic vessel.
2. a lymphatic vessel.

lymphatic aplasia
causes distention of other lymphatics where lymph flow is blocked and local edema.
lymphatic ducts
the two larger vessels into which all lymphatic vessels converge. The right lymphatic duct joins the venous system at the junction of the right jugular and subclavian veins and carries lymph from the cranial right side of the body. The left lymphatic duct, or thoracic duct, enters the circulatory system at the junction of the left jugular and subclavian veins; it returns lymph from the cranial left side of the body and caudal to the diaphragm.
lymphatic enlargement
includes distention with lymph as in lymphangiectasia, or thickened as in cutaneous tuberculosis.
lymphatic flow obstruction
by local compression, congenital, segmental aplasia, lymphangitis, lymphadenitis.
lymphatic follicle
see lymph nodule; may be primary or secondary.
inherited lymphatic obstruction edema
inherited as a single recessive in Ayrshire and Hereford cattle; calves are edematous, locally or generally at birth and do not improve; the defect is in aplasia of lymph vessels and nodes.
lymphatic leukemia
see lymphatic leukemia.
lymphatic lumbar trunks
a plexus of lymphatics on the abdominal roof that drain into the cisterna chyli.
lymphatic nodule
see lymph nodule.
primary lymphatic organs
see lymphoid organs.
secondary lymphatic organs
see lymphoid organs.
lymphatic system
the lymphatic vessels and lymphoid tissue, considered collectively. See also circulatory system.

lymphatic tissue
see lymphoid tissue.
lymphatic vessel obstruction
occurs as a result of pressure from nearby tumors or other space-occupying lesions, because of hypoplasia of lymph nodes in the fetus, in extensive calcinosis, e.g. in Solanum malacoxylon poisoning and in horses not getting sufficient exercise. Called also lymphangiectasia.
lymphatic vessels
the capillaries, collecting vessels, and trunks that collect lymph from the tissues and carry it to the bloodstream; called also lymphatics.
