, Question 1
pts
Explain why a patient with liver disease would have intolerance to fatty
foods.
Your Answer:
They would have an intolerance to fatty food because one of the livers
primary functions is to produce bile. If the person has a diseased liver than
they probably cannot produce a normal amount of bile. Bile is used to break
down fat so that it can be digested and used for energy. If it can't be broken
down than the person will have isses 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
pts
Explain in detail how the stomach contents enter the small intestine.
Your Answer:
The pyloric sphincter is located at the base of the stomach. When it relaxes a
small amount of chyme is able to pass through into the small intestine. Then
there is a reflex that causes it to close temporarily. When it relaxes the
procces starts over again. Its a slow process.
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.
