SOLUTIONS GRADED A+
⩥ The absorptive cells lining the gastrointestinal tract are called:
Answer: Enterocytes

intestine and the pyloric sphincter, involving substance GLP-1, is:
Answer: Ileal brake
⩥ All of the following factors stimulate or increase thirst EXCEPT:
Answer: Increased blood volume presumably detected by cardiac stretch
receptors
⩥ The most common digestive problem associated with carbohydrates is
hypolactasia, which is Answer: a reduced ability to digest the galactose-
glucose bond of milk sugar
⩥ Phytate (phytic acid) is a Answer: derivative of the sugar alcohol,
