Question 1 w

w w w
Explain why a patient with liver disease would have intolerance to fatty foods.
w w w w w w w w w w w w
Your Answer:
w w
Because one of the function of the liver is to produce bile. Bile is used to emulsify fat, if the fat
w w w w w w w w w w w w w w w w w w w w
cannot be broken down, the patient will have intolerance with fatty foods.
w w w w w w w w w w w w
The liver produces bile which breaks down fats. If it is not producing bile (or less bile), fats
w w w w w w w w w w w w w w w w w
will not be broken down effectively.

Question 2 w

Explain in detail how the stomach contents enter the small intestine.
w w w w w w w w w w
Your Answer:
w w
First, the contents enters the small intestine through pyloric sphincter. The pyloric sphincter then
w w w w w w w w w w w w w
relaxes and small amount of chyme pass through into the small intestine. A reflex occurs after
w w w w w w w w w w w w w w w w
chyme enters the small intestine which causes sphincter to close. Once sphincter relaxes again
w w w w w w w w w w w w w w
some more chyme enters and this process continues.
w w w w w w w w
The pyloric sphincter (valve), located at the base of the stomach, relaxes causing a small
w w w w w w w w w w w w w w
quantity of chyme to pass through the opening into the first part of the small intestine.
w w w w w w w w w w w w w w w w
This initiates a reflex that causes the muscles of the sphincter to contract and close the
w w w w w w w w w w w w w w w w
opening temporarily. Then the sphincter relaxes again and allows more chyme to enter.
