Such organs are called vestegial organs. They are remains of evolution. For example, apendix, the nipples in man, the muscles for movement of ears in human beings, and to some extent, the hair in armpits and groin.

vestigial organs are actually present in our bodies brought about by evolution such that our coccyx are present because our ancestors had tails and such explanations.

well, the spleen is an useless organ, so is the appendix seeing as in some people it is a ticking time bomb. If it brusts it can kill you. also the tonsils are pretty useless as well.
