tends to dampen activity is a broad sense. Think of it as a bias to do or a counter bias to do less. The central nervous system can boost either or both. Chemical signaling exists as well; especially upper gut releasing chemical signals to lower gut (get ready for what’s coming).

In the absence of correct control these mechanisms tend to revert to clock like cyclical function. There are tricks to bowel train those with paralysis so as to make toileting not interfere with daily activities. At the most primitive level peristalsis defaults to moving contents from mouth to anus. How? It is easier to visualize in the large colon (bigger and more discrete). First a bowel region narrows closing the lumen at the constriction.
