Question
Which label represents the lacteal?
Markscheme
C
Examiners report
Several teachers commented that the term lacteal is not specified in the programme and should therefore not have been tested in Question 25. This question was based on Assessment Statement 6.1.7, which specifies that students should be able to explain the relationship between the structure of the villus and its functions in absorption and transport. There is no teacher note accompanying this question so no specific structures are included or excluded and the examining team’s view was that it was reasonable to expect knowledge of lacteals which have an important role in transport of absorbed. Two other labels on the diagram were the epithelium and capillaries and well-prepared candidates should have been able to eliminate them even if they then had to guess between the other two answers. In fact nearly 60% of candidates answered this question correctly and the discrimination index was good.
