The digestive system takes in food, digests and absorbs nutrients, and eliminates the remaining waste material. The digestive system can be divided into the digestive tract (oral cavity, esophagus, stomach, small intestine, and large intestine) and associated digestive organs (salivary glands, pancreas, liver, and gallbladder).
Tongue – covered by a specialized mucosa that contains multiple types of papillae and taste buds. This specimen has excellent examples of foliate papillae and taste buds.
Esophagus – a muscular tube through which food passes from the pharynx to the stomach. The wall of the esophagus is composed of the four layers characteristic of the gastrointestinal tract.
Colon – composed of the four layers characteristic of the gastrointestinal tract. However, neither villi nor plicae circularis are present and goblet cells become more frequent.
