Why is dialysis done when kidneys fail?
Answer and explanation
Correct answer: To remove wastes from blood
The governing concept is excretion and maintenance of the internal environment. Healthy kidneys filter blood, remove nitrogenous wastes and excess water or salts, and form urine. When kidney function fails, wastes can accumulate to dangerous levels. During dialysis, blood passes near a dialysis fluid across a partially permeable membrane, allowing selected wastes and excess substances to diffuse out. It does not add food, fill lungs, or produce stomach acid.
