Which of the following is not true of intestinal villi?
A. They possess microvilli
B. They increase the surface area
C. They are supplied with capillaries and the lacteal vessels
D. They only participate in digestion of fats
Answer :
Villi are small finger like folding in small intestine. Villi produce numerous microscopic projections called microvilli. Hence option a is true.
Microvilli increase the surface area enormously. So option b is true.
Villi are supplied with a network of capillaries and a large lymph vessel called the lacteal. So option c is true.
So option d is not true. Digestion of all nutrients is completed in intestine and not fat alone.
Hence the correct answer is option (d).
