Explain why a patient with liver disease would have intolerance to fatty foods.

Your Answer:

Because one of the function of the liver is to produce bile. Bile is used to emulsify fat, if the fat

cannot be broken down, the patient will have intolerance with fatty foods.

The liver produces bile which breaks down fats. If it is not producing bile (or less bile), fats

will not be broken down effectively.

Question 2

5 / 5 pts

Explain in detail how the stomach contents enter the small intestine.

Your Answer:

First, the contents enters the small intestine through pyloric sphincter. The pyloric sphincter then

relaxes and small amount of chyme pass through into the small intestine. A reflex occurs after

chyme enters the small intestine which causes sphincter to close. Once sphincter relaxes again

some more chyme enters and this process continues.

The pyloric sphincter (valve), located at the base of the stomach, relaxes causing a small

quantity of chyme to pass through the opening into the first part of the small intestine.

This initiates a reflex that causes the muscles of the sphincter to contract and close the

opening temporarily. Then the sphincter relaxes again and allows more chyme to enter.
