Study Notes
Food Processing in the Digestive System
- The digestive tract processes food regardless of its type.
- Food is crushed by teeth to create particles of similar size and texture.
- The digestive tract lining is soft, so food is moistened for smooth passage.
- Saliva, secreted by salivary glands, aids in moistening food.
- The complex nature of food requires breakdown into smaller molecules for absorption.
- This breakdown is facilitated by enzymes, which act as biological catalysts.
