Mechanical characteristics of GI motility.

System Pressure wave amplitude Contraction phenomenon Pressure wave frequency Electrical activity References
Esophagus 40–180 mmHg (swallowing), 5–10 mmHg (peristaltic amplitude) Connected to CNS Swallowing, 1–2 min−1 [327,328]
Stomach <10 mmHg (antral), 60.5 ± 8.9 mmHg (Pylorus, Phase III) MMC 1–3 min−1 (antral, Phase III) ≈3 min−1 (Slow wave) [329]
Small intestine 18–62 mmHg (Phase III) MMC 11 min−1 (Phase III) 10–20 min−1 [318,322]
Large Intestine 14.6 ± 11.1 mmHg (simultaneous pressure waves) Peristatis/retroperistatis, giant migrating contractions Simultaneous pressure wave, 1.4 ± 0.6 min−1, 1–2 day−1 (giant migrating contractions) 3–8 min−1 (Slow wave) [330]
