Which muscles in the gut wall are involved in peristalsis?
Circular muscles - reduce the diameter of the gut when they contract
Longitudinal muscles - which reduce the length of the gut when they contract
The muscles work together to produce wave-like contractions. These have a ‘squeezing action’ that pushes the bolus through the gut.
