| artificial kidney | A machine for haemodialysis in acute or chronic renal failure; toxic substances in the blood are removed by exposure to dialyzing fluid across a semipermeable membrane. Synonym: artificial kidney. Ultrafiltration haemodialyzer, a haemodialyzer that uses fluid pressure differentials to bring about loss (usually) of protein-free fluid from the blood to the bath, as in certain edematous conditions.

| artificial respiration | Application of mechanically or manually generated pressures, usually positive, to gas(es) in or about the airway as a means of producing gas exchange between the lungs and surrounding atmosphere. Synonym: artificial respiration. (05 Mar 2000) |
| artificial selection | <genetics> The selective breeding by humans towards a desired trait in a plant, animal, or other organism which is of value (usually economic) to the humans. The process operates on the same principles as natural selection. (09 Oct 1997) |
