The intestinal wall has invaginations (or dips) that have a much larger surface ares compared to a simple tube
Three Modifications: villi, microvilli, and plicae circulares...
mucosal folds, villi, microvilli
the villi that absorbs nutrients
Villi, microvilli and plicae circularis
Microvilli
Pustobleyto
Microvilli, villi, plicae circulares, if choosing just one i would go with microvilli because the tremendously increase the surface area for absorption in the absorptive cell
Microvilli:In some cells the membrane is thrown into minute fingerlike projections or folds called microvilli which greatly increase the surface area of the cell available for absorption or passage of materials and for the binding of signaling molecules.
The small intestine is thrown into folds that increase its surface area by upto 600 times. This helps in the absorption by providing greater area for diffusion to take place through. Each villus (projection) also has a lacteal inside it, which helps in the absorption of lipids.
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.
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 :)
Villi are part of the structure of the small intestine(ileum). They help increase surface area for absorption of nutrients.

finger like projections in small intestine are called villi to increase surface area for absorption of food in small intestine.
Villi are tiny fingerlike projects that increase a cells absorption capabilities by increasing its surface area.
Rugae and plicae circularis.

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
They increase the surface area of small intestine and thus, increase the rate of absorption of food...
Tiny projections on the free surface of some epithelial cells; increase surface area for absorption
