Question
A structure has a thin epithelium of one cell layer and contains a lacteal and blood capillaries. It has protein channels and mitochondria to aid absorption. What is this structure?
A. Alveolus
B. Gastric gland
C. Pancreas
D. Villus
Markscheme
D
Examiners report
This question was quite easy for most candidates, probably due to the fact that the lacteal is only present in the villus therefore very easy to spot the right answer.
