The liver produces bile which breaks down fats. If it is not producing bile (or less bile), fats will not bebroken
down effectively.
2. Explain in detail how the stomach contents enter the small intestine.
The pyloric sphincter (valve), located at the base of the stomach, relaxes causing a small quantity ofchyme to

This initiates a reflex that causes the muscles of the sphincter to contract and close the openingtemporarily.
Then the sphincter relaxes again and allows more chyme to enter.
