The gastrointestinal tract is the continuous muscular tube extending from the mouth to the anus, comprising the oral cavity, pharynx, esophagus, stomach, small intestine, and large intestine, together with accessory organs such as the liver, gallbladder, and pancreas that secrete digestive fluids. Its principal functions are the mechanical and chemical breakdown of food, the absorption of nutrients, water, and electrolytes, and the elimination of waste, processes coordinated by enteric neural networks, hormones, and a vast resident microbiota that contributes to digestion, immunity, and metabolic homeostasis. The mucosal lining serves both as an absorptive surface and as a barrier and immune interface, and the tract is subject to a wide spectrum of disease, including inflammatory, infectious, functional, and neoplastic disorders. Diagnosis and management draw on endoscopy, imaging, histopathology, and increasingly on understanding of the gut microbiome and gut-brain interactions. Themes in the associated literature include surgical correction of digestive-system reflux and its clinical manifestations, metastatic malignant melanoma and other rare tumors of the gastrointestinal tract, gastrointestinal tuberculosis and fistula formation, small-intestinal bacterial overgrowth, the role of antimicrobial resistance in gastrointestinal infection, food-preservative and health-promoting plant compounds, peptide-based nutrition in pediatric populations, and the gastrointestinal effects of Helicobacter pylori. This journal publishes peer-reviewed research on the structure, function, and disorders of the gastrointestinal tract and its intestinal segments.
