Question
What is an important function of the lacteal in the villus?
A. Secretion of mucus
B. Secretion of enzymes
C. Transport of glucose
D. Transport of fats
Markscheme
D
Examiners report
Feedback from the G2 forms implied that it is unclear whether the function of the lacteal is a required part of the knowledge of the digestive system. Assessment statement 6.1.7 of the core syllabus requires students to explain how the structure of the villus is related to its role in absorption. It was therefore felt that the lacteal was a necessary part of the understanding of the villus, and that the question was fair. Many candidates gave options A, B and C as the answer, but the question did discriminate well, with the majority choosing D, the correct response.
