胃肠蠕动在英语中可以翻译为 "peristalsis". 这个词来自希腊语 "peristallein", 意思是"包围"或"环绕".
Peristalsis是指胃肠道内的肌肉收缩和松弛，使内容物在胃肠道中向前移动的过程。例如：
The peristalsis in the small intestine helps to move food along the digestive tract. (小肠中的胃肠蠕动有助于将食物沿消化道移动。)
Peristalsis is essential for proper digestion. (胃肠蠕动对于正常消化至关重要。)
If the peristalsis in the colon is slowed down, it can lead to constipation. (如果结肠中的胃肠蠕动减慢，可能导致便秘。)
