1. Explain why a patient with liver The liver produces bile which breaks
disease would have intolerance to down fats. If it is not producing bile (or
fatty foods. less bile), fats will not be broken down
effectively.
2. Explain in detail how stomach The pyloric sphincter valve, located at
contents enter small intestine the base of the stomach, relaxes caus-
ing 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 sphinc-
ter to contract and close the opening
temporarily. Then the sphincter relaxes
again and allows more chyme to enter.
3. A patient experiencing vitamin B. Fat soluble vitamin, they are stored
toxicity. What type of vitamin within the body's fat stores making it
would be causing this toxicity? harder for the body to rid itself of them.
A. Water soluble vitamin
B. Fat soluble vitamin
C. All of the above
4. Explain each digestive system Digestion and Absorption
functions are carried out by the Chemical digestion continues as en-
small intestine zymes 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 mol-
ecules, water and fat are absorbed into
the bloodstream.

when food is moved, mixed and ex-
posed to enzymes along the gastroin-
testinal tract. Divided into two parts, me-
