peristaltic
Digestive tract contractions
Peristaltic describes the wave-like muscular contractions that move contents through tubular organs.
The esophagus uses peristaltic motion to push food toward the stomach; intestines move digested material the same way.
Peristaltic pumps mimic this squeezing action mechanically, useful when fluids must stay uncontaminated by pump components.
