| kallikrein system | A blood serum system, the activity of which is initiated by factor XII (Hageman factor) leading to the production of prekallikrein activator and then to kallikrein which, after activation by plasmin, splits bradykinin from kininogen. (05 Mar 2000) |
|---|---|
| kidd blood-group system | A group of antigens consisting principally of jk(a) and jk(b), determined by allelic genes. Amorphs are encountered. Antibodies of these substances are usually weak and quite labile, stimulated by erythrocytes. (12 Dec 1998) |
| Zaffaroni system | A chromatographic system for the separation of steroids. (05 Mar 2000) |
| kinetic system | A term proposed by G.W. Crile to denote the chain of organs through which latent energy is transformed into motion and heat: it includes the brain, the thyroid, the adrenals, the liver, the pancreas, and the muscles, that part of the neuromuscular system whereby active movements are effected; distinguished from the static system. (05 Mar 2000) |
| feedback system | A complex of neuronal circuits whereby a part of the efferent path returns to the input to modulate its activity, thus acting as a governor on the system. See: feedback. (05 Mar 2000) |
| urinary system | The organs concerned in the production and excretion of urine, together with the organs of reproduction. (12 Dec 1998) |
| urogenital system | The organs concerned in the production and excretion of urine, together with the organs of reproduction. (12 Dec 1998) |
| uropoietic system | The kidneys, ureters, bladder, and urethra, considered as a system for the secretion and excretion of urine. (05 Mar 2000) |
| filling defect in renal collecting system | <radiology> Common causes: transitional cell carcinoma, blood clot, lucent calculus (urate) less common causes: fungus ball, sloughed papilla, fibroepithelial polyp, invasion by hypernephroma, malakoplakia, vessel impression, metastases (12 Dec 1998) |
| foot-pound-second system | <mechanics> A system of absolute units based on the foot, pound, and second. (05 Mar 2000) |
| lateral line system | A series of sense organs that detect pressure or vibrations along the head and side of cyclostomes, fishes, and some amphibians. (05 Mar 2000) |
| fuel handling system | A system for unloading wood fuel from vans or trucks, transporting the fuel to a storage pile or bin, and conveying the fuel from storage to the boiler or other energy conversion equipment. (05 Dec 1998) |
| lewis blood-group system | A group of dominantly and independently inherited antigens associated with the abo blood factors. They are glycolipids present in plasma and secretions that may adhere to the erythrocytes. The phenotype le(b) is the result of the interaction of the le gene le(a) with the genes for the abo blood groups. (12 Dec 1998) |
| light harvesting system | Set of photosynthetic pigment molecules that absorb light and channel the energy to the photosynthetic reaction centre, where the light reactions of photosynthesis occur. In higher plants, contains chlorophyll and carotenoids and is present in two slightly different forms in photosystems I and II. (18 Nov 1997) |
| limbic system | Collective term denoting a heterogeneous array of brain structures at or near the edge (limbus) of the medial wall of the cerebral hemisphere, in particular the hippocampus, amygdala, and fornicate gyrus; the term is often used so as to include also the interconnections of these structures, as well as their connections with the septal area, the hypothalamus, and a medial zone of mesencephalic tegmentum. By way of the latter connections, the limbic system exerts an important influence upon the endocrine and autonomic motor system's; its functions also appear to affect motivational and mood states. Synonym: visceral brain. (05 Mar 2000) |
