A&P 1 101 MODULE 3 EXAM 3 DIGESTIVE
SYSTEM ACTUAL TEST PAPER 2026 COMPLETE
QUESTIONS AND SOLUTIONS GRADED A+
◉ Explain why a patient with liver disease would have intolerance to
fatty foods. Answer: The liver produces bile which breaks down fats.
If it is not producing bile (or less bile), fats will not be broken down
effectively.
◉ Explain in detail how stomach contents enter small intestine
Answer: 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.
◉ A patient experiencing vitamin toxicity. What type of vitamin
would be causing this toxicity?
A. Water soluble vitamin
B. Fat soluble vitamin
C. All of the above Answer: B. Fat soluble vitamin, they are stored
within the body's fat stores making it harder for the body to rid itself
of them.
, ◉ Explain each digestive system functions are carried out by the
small intestine Answer: Digestion and Absorption
Chemical digestion continues as enzymes from the pancreatic juices
break down starches and proteins, and begin digestion of fat.
Mechanical digestion continues as bile breaks down fat into smaller
pieces
Absorption begins as digested food molecules, water and fat are
absorbed into the bloodstream.
◉ Explain which digestive system functions are carried out by the
large intestine. Answer: Absorption: water and electrolytes are
reabsorbed and vitamins are absorbed.
Defecation: feces return to the rectum where it is excreted via the
anus
◉ Name and explain four main functions performed by the digestive
system Answer: 1. Ingestion: when food enters the mouth
2. Digestion: food breakdown occurs when food is moved, mixed and
exposed to enzymes along the gastrointestinal tract. Divided into
two parts, mechanical and chemical.
A. Mechanical occurs when food is broken down in small pieces
using the teeth to chew food.
B. Chemical is the breakdown of food by enzymes
