@atomedgeanatomy: Ever wonder how your stomach stretches after a big meal? Meet the rugae...your belly’s secret folds! These ridges allow your stomach to expand multiple times its original size. They help to maximize surface area for release of digestive enzymes and acid whilst their seemingly random pattern helps churn your food to form chyme. #stomachanatomy #rugaefolds #digestiveanatomy #medstudentcontent #clinicalanatomy #humanbodyfacts #anatomyvideo #guthealthscience #3danatomyexplained #medicalvisuals
