Food moves through the digestive tract via peristalsis (rhythmic contractions) and segmentation (mixing contractions).
Food movement occurs via peristalsis (rhythmic contractions of longitudinal and circular muscles causing unidirectional movement) and segmentation (non-adjacent segment contractions in the intestines causing bidirectional mixing).
