Chemical and Physical Processes in the Digestive System Answer Key

Focus on the breakdown of food molecules by enzymes and their mechanical breakdown through chewing and stomach churning. Each action plays a distinct role in preparing nutrients for absorption.

For accurate assessment: Match each action with its corresponding function, such as identifying which part of the body initiates enzymatic digestion or where physical grinding occurs. These tasks are crucial for nutrient breakdown and transport.

Tip: Review the stages carefully: enzymatic breakdown typically occurs in the small intestine, while physical grinding happens in the mouth and stomach. Knowing these stages will solidify your understanding of nutrient absorption.
