The Human Stomach: Structure & Function The stomach is a muscular digestive organ that stores, mixes, and breaks down food before passing it to the small intestine. • Entry (Esophagus & Cardia): Allows food in, prevents acid reflux. • Fundus: Temporary storage of food and gases. • Body (Corpus): Churns food with acid and enzymes to form chyme. • Rugae: Folds that expand after meals. • Pyloric Region: Controls release into the duodenum.
