Is the tissue in the intestines ciliated?
No cells of small intestine do not have cilia. The main functions of small intestine is absorption of digested food. Hence, its surface area has to be large. Villi and microvilli serve this purpose and increase the surface area of mucosa many fold. Also, the diameter of small intestine if large enough so no cilia is required, for passage of food too.
Thin walled extensions of root epidermis that increase surface area for absorption?
root hair
Why is the inner mitochondrial membrne folded?
The mitochondrial membrane's cristae are similar in size to villa lining the intestine and are there for much of the same purpose, to increase surface area for absorption.
What are the microscopic hairs on your taste buds called and what do they do?
They are not actually hairs but hair-like projections that increase the surface area of your taste buds, gustatory organs, and they are called cilia.
What is the function of micro villi in the kidney?
To increase the surface area of the tubule. It creates a larger surface area for re-absorption to occur, and thus more diffusion can occur at once.
What has tiny fingerlike projects that increase a cells absorption capabilities by increasing its surface area?
Villi are tiny fingerlike projects that increase a cells absorption capabilities by increasing its surface area.

How is ileum of a mammal adapted for the absorption of digested food?
1/ the lining has A a very large surface area. 2/ the length of the intestine (ileum 3.5m) help increase the surface surface area for absorption. 3/ millions of villi provide a large surface area in contact with the digested food. 4/ hundreds of micro villi on the surface cells (on each villus) increase the surface area for absorption. your welcome :)
What is the function of projection?
They increase the surface area of small intestine and thus, increase the rate of absorption of food...
What is microvilli'?
Tiny projections on the free surface of some epithelial cells; increase surface area for absorption
What is the purpose of the microvilli in the proximal convoluted tubule?
Microvilli are the finger like projections present on the outer surface of the cell. Their function is to increase the surface area of the cells through which the diffusion of materials both into and out of the cell occur. They are also involved in absorption, secretion and cellular adhesion.
Which of these is the best definition for cilia?
Cilia are tiny hairlike projections in, for example the small intestine, that increase the surface area. They usually have a good blood supply.
What substances in the small intestine of humans serve to increase the surface area for absorption?
Villi
What might be the advantage of the folds and coils of the small intestines?
slows down the passage of the food slomg the intestines, and afford an increased surface for absorption. Increase the surface area for the intestines to increase absorption of nutrients
What are the folds of the plasma membrane that increase the cells surface area?
microvilli increase surface area for absorption
What are the finger like projections in the small intestine that act to increase the surface for absorption?
finger like projections in small intestine are called villi to increase surface area for absorption of food in small intestine.
Increase the membrane surface area?
You may be talking about microvilli.
