What problem may occur if kidneys do not filter blood properly?
Answer and explanation
Correct answer: Waste materials may accumulate in blood
The governing concept is kidney function in excretion and maintenance of the internal environment. Metabolism continuously produces wastes such as urea, and healthy kidneys filter these substances from the blood and remove them in urine while regulating water and salts. If filtration is seriously impaired, wastes and excess substances remain in the bloodstream, causing harmful imbalance and illness. Thus option A is correct; the other options concern impossible or unrelated events.
