Villi Flashcards
1
Q
What does the rich blood suply produce?
A
A steep concentration gradient for efficient diffusion
2
Q
What is a fact about the surfaces area?
A
It has a large surface area for diffusion.
3
Q
Why does it have a thin wall?
A
The thin way (one cell thick) so there is only a short distance across which diffusion takes places.
4
Q
What does the lymph system do?
A
Little lymph capillaries called lacteals are found within each villus. Through their absorption of fats and fat-soluble vitamins, they produce chyle, a milky white fluid.
5
Q
What do mitochondria do?
A
The mitochondria gives the villi energy to carry out diffusion.
