Including the 7th in the chord (or playing it instead of the 5th) lets you hear a clear difference in the dominant chord (major 3rd, minor 7th). In the V-I chord progressions it's particularly useful because you hear the resolution from the tritone formed by the major 3rd+minor 7th to the root+major 3rd of the tonic.
Keeping this in consideration, why are seventh chords used?
Because the interval between the 3rd and the 7th creates a diminished 5th, a very unstable, dissonant interval that practically begs to be resolved inwards, to notes which just happen to be the 1st and 3rd degree of the tonic chord. Use this chord to create a strong V to I feel.
Additionally, why is the 7th chord diminished? Because these chords have no leading tone in relation to the chords to which they resolve, they cannot properly have dominant function. They are therefore referred to commonly as non-dominant diminished seventh chords or common tone diminished seventh chords (see below).
