Yes, villi are present in all three. Small soluble food molecules broken down by enzymes in bile (which is released in the ileum) are absorbed by the villi in the ileum. Water molecules are absorbed by villi in the duodenum (large intestines) by active transport - not osmosis, against a concentration gradient.
They're much more numerous in the duodenum than in the ileum.
They are called Villi.
Glycerol and fatty acids are absorbed in the duodenum through a process called passive diffusion. Once the fat molecules are broken down into smaller components, such as glycerol and fatty acids, they can be absorbed by the villi in the small intestine and then transported into the bloodstream.
Villi is plural. One is Villus, many are Villi.
Sucrase is secreted by the brush border cells of the small intestine, specifically the duodenum and the jejunum. It is an enzyme involved in breaking down sucrose into its simple sugar components, glucose and fructose, for absorption into the bloodstream.
More than 50% must be removed before there is a significant reduction in capability Duodenum and jejunum can perform each other's roles in digestion and absorption

the villi in the small intestines.
The term that describes part of the small intestine is the "duodenum."
Because Grandpa Joe Said So! Co Za Asy
Villi are so small because they are only made of one cell- they are single celled organisms
