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.
