Study Notes
Digestive System Overview
- This chapter covers normal and clinical aspects of the digestive system
- Duration: 1.5 hours
- Major Topics:
- Normal structure and general functions of the digestive system
- Roots related to the digestive system
- Clinical symptoms and disorders of the digestive system
- Common abbreviations and medical terminologies
Digestive System Functions
- The digestive system processes food and liquids for absorption into the bloodstream
- It consists of the digestive tract (series of structures and organs)
- The digestive tract processes food and liquids
- Other organs contribute digestive juices to the process
Organs of the Digestive Tract (Diagrammed)
- Oral Cavity (Mouth): Chewing and mixing food with saliva (containing amylase)
- Pharynx: Swallows food by reflex action
- Esophagus: Moves food to the stomach by peristalsis
- Stomach: Stores food, mixes it with digestive juices (HCl and pepsin)
- Small Intestine: Secretes enzymes and receives secretions, processes food for absorption
- Pancreas: Secretes digestive enzymes and bicarbonate
- Liver: Secretes bile salts to break down fats
- Gallbladder: Stores bile and releases it into the digestive tract
- Large Intestine: Processes undigested waste
Accessory Organs (Diagrammed and Described)
- Salivary Glands: Produce saliva containing amylase
- Liver: Produces bile, processes nutrients
- Gallbladder: Stores bile
- Pancreas: Secretes digestive enzymes
Normal Structure and Function
- Anus: The distal opening of the digestive tract
Roots and Meanings (Mouth, specific examples included)
- Bucc/o: Cheek
- Buccversion: Turning toward the cheek
- Dent/i, Dent/o: Tooth, teeth
- Edentulous: Without teeth
Roots Related to Digestive Tract (Examples Provided)
- Esophag/o: Esophagus
- Esophageal: Pertaining to the esophagus
- Gastr/o: Stomach

Roots for Accessory Organs, including examples
