What is peristalsis?
- Involuntary contraction and relaxation of muscles of the intestine or other canal.
- Peristalsis moves food through your digestive system, beginning in your throat when you swallow and continuing through your esophagus, stomach and intestines while you digest.
- automatic wave-like movement of the muscles that line your alimentary canal
- This slow but steady process gives your body time to break food down for digestion and to absorb nutrients along the way.
- The parasympathetic nervous system (PNS) stimulates peristalsis via the myenteric plexus.
