Peristalsis is a series of muscle contractions. These contractions occur in your digestive tract. Peristalsis is also seen in the tubes that connect the kidneys to the bladder.

Peristalsis is an automatic and important process. It moves:

Food through the digestive system
Urine from the kidneys into the bladder
Bile from the gallbladder into the duodenum
Peristalsis is a normal function of the body.

Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. ... There, the food is churned into a liquid mixture called chyme that moves into the small intestine where peristalsis continues. Stretching out a piece of intestine will make it easier to see the wave-like motion

Marina CMI [18]

After the  adenylyl cyclase reaction (which  convert ATP into cyclic adenosine monophosphate-cAMP), cAMP level is directly increased. Next steps of PKA activation include:

• cAMP binding to regulatory subunits of PKA, as a result conformational change in the regulatory subunits of PKA is induced,

•  catalytic subunits are detached and unleashed by regulatory subunits and as a result activated.
