Answers
a) It is basically a machine that purifies your blood and separates it from harmful substances in your blood (the work your kidneys actually do).
b) When one or both the kidneys fail, your blood is not purified hence leading to increase in the harmful substances, so this treatment becomes necessary to be taken.
PS: the harmful substances can mainly be called urea, uric acid and ammonia.
