Peristaltic movement comprises relaxation of circular smooth muscles, then their contraction behind the chewed material to keep it from moving backward, then longitudinal contraction to push it forward. Earthworms use a similar mechanism to drive their locomotion, and some modern machinery imitates this design.
Peristalsis is also involved in the mixing of the food with the digestive juices and in breaking it down from lumps into a thick paste which is then squeezed through the body. This increases the surface area of food available to the digestive enzymes.hysical digestion. Part of the digestive process which breaks down the food you eat into the small, soluble molecules you need is physical. This involves breaking the food down into smaller pieces which are easier to move along your digestive tract.
