How can dialysis be life-saving when the kidneys fail?
Answer and explanation
Correct answer: It helps remove wastes from the blood artificially
The governing concept is excretion and maintenance of the internal environment. Healthy kidneys filter the blood, remove nitrogenous wastes and excess water or salts, and form urine. When kidneys fail, these substances can accumulate and disturb body function. Dialysis uses a special membrane and dialysis fluid to remove some wastes and excess water from blood. Thus option A is correct; the other options concern unrelated organs or plant functions.
