1. Explain why a patient with liver disease may have
intolerance to fatty foods.
CORRECT ANSWER: Reduced bile production or impaired
bile flow can interfere with fat digestion and absorption.
Explanation:
The liver produces bile, which is stored and concentrated in the
gallbladder and released into the small intestine. Bile salts
emulsify fats, breaking large fat globules into smaller droplets
and increasing the surface area available for pancreatic lipase.
Liver disease can reduce bile production or impair bile
secretion, resulting in inadequate fat digestion and absorption.
This may cause intolerance to fatty foods, abdominal
discomfort, diarrhea, and fatty stools (steatorrhea).
,2. Food enters the stomach from the _____ via the _____
sphincter. Food exits the stomach via the _____ sphincter
into the _____.
Choices:
A. Esophagus; lower esophageal sphincter; pyloric sphincter;
duodenum
B. Pharynx; pyloric sphincter; lower esophageal sphincter;
jejunum
C. Esophagus; pyloric sphincter; lower esophageal sphincter;
duodenum
D. Duodenum; lower esophageal sphincter; pyloric sphincter;
jejunum
CORRECT ANSWER: A. Esophagus; lower esophageal
sphincter; pyloric sphincter; duodenum
Explanation:
Food travels from the esophagus into the stomach through the
lower esophageal sphincter, which helps prevent gastric
, contents from refluxing into the esophagus. After digestion and
mixing with gastric secretions, stomach contents, called chyme,
leave through the pyloric sphincter and enter the duodenum,
the first portion of the small intestine.
3. Label the following organs of the digestive system.
Identify the specific intestinal regions where indicated.
CORRECT ANSWERs:
• 3: Stomach
• 4: Gallbladder
• 7: Jejunum
• 9: Appendix
• 10: Rectum
Explanation:
Accurate identification of digestive structures requires
distinguishing specific regions rather than using broad terms
such as "small intestine" or "large intestine." The jejunum is the
middle section of the small intestine, the appendix is a narrow
