because the contraction of your abdominal (and other torso-)muscles pushes a bit against your lungs, which makes air escape. This air passes your vocal cords and throat and since the muscles present there are also contracting, you'll produce a specific grunting sound.
Roses are red,
Violets are blue.
Most poems rhyme,
but this one doesn't
