Item EB074001: After eating a meal, the level of glucose is higher in blood flowing away from the small intestine than toward it, whereas after an overnight fast the level of glucose is low in both blood flowing toward and flowing away from the small intestine.
Scientists are studying the relationship between the food a person eats and the level of glucose in the person’s blood stream. They measure the levels of glucose in the blood flowing toward and away from the small intestine at two time points; (1) one hour after the person eats a meal and (2) after the person has fasted overnight for eight hours. Which of the following graphs represents the levels of glucose in the blood flowing toward and away from the small intestine at the two time points?
