The complete digestive tract, also known as the alimentary canal, is a long tube starting from the mouth and ending at the anus. It consists of the mouth, esophagus, stomach, small intestine (duodenum, jejunum, and ileum), large intestine (colon), and rectum. This system is responsible for breaking down food, absorbing nutrients, and eliminating waste.
