The gastrointestinal tract is the path food takes from mouth to anus. It consists of the mouth (chewing, enzyme-assisted breakdown), esophagus (food propulsion), stomach (churning, storage), small intestine (nutrient absorption, hydrolysis), large intestine (absorbing water, ions, vitamins), rectum (storing waste), and anus (expelling waste). Each part plays a crucial role in digestion.
