Study Notes
Digestive Tract Functions
- Mastication's main function is mechanical breakdown of food into smaller particles, increasing the surface area for enzymatic digestion.
- Salivary amylase, gastric amylase, and trypsin are secreted within the digestive tract, but insulin is NOT secreted in the digestive tract.
Hormone Release
- Hormone release in the digestive tract stimulates digestive enzymatic secretions, regulates appetite, and modulates gut motility.
Digestion Process
- Hydrolysis is the process that occurs in the digestive tract to break down large macromolecules in food into smaller molecules.
Motility Function
- The primary function of motility in the digestive tract is to mix food with digestive enzymes and move the food bolus through the digestive system, facilitating digestion and absorption.
