Accessory Organs in Digestion: The Liver, Pancreas, and Gallbladder

Definition

Accessory organs in digestion, including the liver, pancreas, and gallbladder, are not directly part of the digestive tract but contribute significantly to the digestion process by producing and secreting enzymes, bile, and other substances. These organs work in concert to break down food into nutrients that can be absorbed by the body.
