Study Notes
Digestive Tract Processing
- Food needs to be processed into small, uniform particles for efficient digestion.
- Teeth crush food to achieve this.
- The alimentary canal lining is soft; saliva lubricates food for smooth passage.
- Saliva, secreted by salivary glands, is more than just water.
- Food is complex and must be broken down into smaller molecules for absorption.
- Enzymes, biological catalysts, facilitate this breakdown.
