Organs that are not part of the digestive tract but contribute to its functioning, such as by secreting substances that aid in digestion. Some such organs include:

- Salivary glands
- Liver
- Gallbladder
- Spleen
- Pancreas

Accessory Digestive Organs

The mouth, or oral cavity, serves as the first step in food processing, with its parts contributing to both mechanical and chemical digestion before passing the food along to the GI tract. Some parts of the digestive system include:

- Tongue
- Teeth
- Lips
- Gums
