Peristalsis is strictly mechanical. If you think of pedaling a bicycle up and down small rolling hills, that is like the mechanical action of peristalsis. It keeps pushing foodstuffs forward--even when you become constipated, the muscles will still try to keep 'pedaling'. Chemical action involves enzymes or bile.
