Textbook Question
Chapter 47, Problem 7TYK
If the fat in whole milk is ingested:
a. the stomach, with its high pH, will stimulate cells of the duodenum to hasten stomach emptying.
b. parietal cells in the stomach will absorb it.
c. in the small intestine, bile salts emulsify the fats and then lipase hydrolyzes them.
d. lactase deficiency in the small intestine would prevent its digestion.
e. microvilli will absorb the fat in the form of chylomicrons directly into the blood of the hepatic portal vein.
