RATIONALES PORTAGE LEARNING | UPDATED 2026/2027
SECTION 1: THE DIGESTIVE SYSTEM – OVERVIEW & ALIMENTARY
CANAL
1. Which of the following is NOT a function of the digestive system?
a) Ingestion of food
b) Mechanical and chemical digestion
c) Absorption of nutrients
d) Production of hormones that regulate blood glucose
Correct Answer: d) Production of hormones that regulate blood glucose
Rationale: The digestive system functions in ingestion, mechanical and chemical
1
, digestion, absorption of nutrients, and elimination of wastes. Production of
hormones that regulate blood glucose (insulin and glucagon) is a function of the
endocrine system (pancreas) [citation:4].
2. The digestive system consists of the alimentary canal and:
a) The lymphatic system
b) The accessory digestive organs
c) The respiratory system
d) The urinary system
Correct Answer: b) The accessory digestive organs
Rationale: The digestive system is composed of the alimentary canal
(gastrointestinal
tract) and the accessory digestive organs (teeth, tongue, salivary glands, liver,
gallbladder, and pancreas) [citation:4].
3. Which of the following is an accessory digestive organ?
a) Stomach
b) Small intestine
c) Liver
d) Esophagus
Correct Answer: c) Liver
Rationale: The liver is an accessory digestive organ that produces bile for fat
2
, digestion. The stomach, small intestine, and esophagus are part of the alimentary
canal (GI tract) [citation:4].
4. Which of the following is part of the alimentary canal?
a) Liver
b) Gallbladder
c) Pancreas
d) Esophagus
Correct Answer: d) Esophagus
Rationale: The alimentary canal includes the mouth, pharynx, esophagus,
stomach,
small intestine, and large intestine. The liver, gallbladder, and pancreas are
accessory organs [citation:4].
5. The serous membrane that lines the abdominal cavity wall is called the:
a) Visceral peritoneum
b) Parietal peritoneum
c) Mesocolon
d) Falciform ligament
Correct Answer: b) Parietal peritoneum
Rationale: The parietal peritoneum lines the abdominal cavity wall. The visceral
peritoneum covers the organs. The mesocolon attaches the colon to the posterior
3
, wall, and the falciform ligament attaches the liver to the anterior wall [citation:4].
6. Which of the following is a function of the stomach?
a) Absorption of most nutrients
b) Mechanical and chemical digestion of food (chyme formation)
c) Absorption of water and electrolytes
d) Production of bile
Correct Answer: b) Mechanical and chemical digestion of food (chyme
formation)
Rationale: The stomach mechanically churns food and chemically digests it using
gastric juices (including hydrochloric acid and pepsin), forming a semi-liquid
mixture called chyme [citation:4].
7. What is the correct order of the small intestine sections?
a) Jejunum, duodenum, ileum
b) Duodenum, jejunum, ileum
c) Ileum, jejunum, duodenum
d) Duodenum, ileum, jejunum
Correct Answer: b) Duodenum, jejunum, ileum
Rationale: The small intestine consists of three sections: the duodenum (first and
shortest), the jejunum (middle), and the ileum (final and longest) [citation:4].
