n. pl. di·al·y·ses (-sēz′)
1. The separation of smaller molecules from larger molecules or of dissolved substances from colloidal particles in a solution by selective diffusion through a semipermeable membrane.
2. Medicine Any of several techniques, especially hemodialysis and peritoneal dialysis, in which filtration through a semipermeable membrane is used to remove metabolic wastes and excess fluid from the blood of people with kidney failure.
[Greek dialusis, separating, dissolution, from dialūein, to break up, dissolve : dia-, apart; see dia- + lūein, to loosen; see leu- in Indo-European roots.]
di′a·lyt′ic (-ə-lĭt′ĭk) adj.
n, pl -ses (-ˌsiːz)
1. (Chemistry) the separation of small molecules from large molecules and colloids in a solution by the selective diffusion of the small molecules through a semipermeable membrane
[C16: from Late Latin: a separation, from Greek dialusis a dissolution, from dialuein to tear apart, dissolve, from luein to loosen]
di•al•y•sis(daɪˈæl ə sɪs)
n., pl. -ses (-ˌsiz)
1. the separation of crystalloids from colloids in a solution by diffusion through a membrane.
2. the process, used in treating kidney disease, by which uric acid and urea are removed from circulating blood by means of a dialyzer.
[1580–90; < Late Latin < Greek diálysis a separation, derivative of dialý(ein) to part, separate (dia- dia- + lyein to loosen)]
di`a•lyt′ic (-əˈlɪt ɪk) adj.
1. The separation of the smaller molecules in a solution from the larger molecules by passing the solution through a membrane that does not allow the large molecules through.
2. The removal of wastes from the bloodstream by a machine that performs dialysis when the kidneys do not function properly.
the process whereby colloids and crystalloids separate in solution by diffusion through a membrane. — dialytic, adj.See also: Biology
A method of compensating for poorly functioning kidneys by using a machine to artificially remove waste products from the blood.
