The digestive system comprises the gastrointestinal tract and accessory organs, facilitating food processing through ingestion, propulsion, secretion, mechanical and chemical digestion, absorption, and defecation. The gastrointestinal tract consists of four layers: mucosa, submucosa, muscularis, and serosa, with various organs including the mouth, esophagus, stomach, and intestines.
