Answer to Question 1

1
Rationale:
1. This is the correct sequence of digestion
2. The sequence of small and large bowel is out of order, and ascending colon is missing.
3. The duodenum and jejunum are missing.
4. The sequence is incorrect.

Answer to Question 2

1
Rationale:
1. Stomach capacity of the newborn is very small, and stomach capacity increases with age.
2. Emptying time of the stomach decreases with age.
3. Saliva production diminishes with age.
4. Infants have fewer enzymatic enzymes, and therefore have a slower rate of digestion that the adult. As enzymes increase with age, rate of digestion increases.
