Illeum Absorption And Villi Flashcards
1
Q
Three ways a ileum is adapted to absorb the food
A
A large surface area because of its long lengths and folds and lots of villi sticking out
Thin and permeable membranes
A good blood supply that’s ensures a concentration gradient is maintained
2
Q
Villi adapted to their jobs
A
Villi are one cell thick so here’s a short diffusion pathway
Increase the surface area
Excellent blood supply for maximum absorption
3
Q
What breaks down fats and proteins and starch in the villi
A
Lacteals absorbs fats
Capillary network proteins and starch
