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.

∙ 9y agoThe villi differ in the duodenum and the ileum of a cat in that the duodenum's villi are leaf like and large in size. This is because the duodenum is the most active site of absorption. In the ileum, the villi are narrower and shorter as they go along the small intestine.

What is the structure in the small intestine for absorbing?
the villi in the small intestines.
What does the ileum do in the digestion system?
Ileum is the last part (division) of small intestine. It absorbs all the remaining food that was not absorbed by jejunum. It contains microscopic villi that are responsible for assimilation of food.
What are The walls of the small intestine are covered in?
The internal walls of the small intestine are lined with villi, which absorb nutrients from the intestine, into the bloodstream. Villi are hair-like protrusions, and because there are millions of them, it means that enough molecules are absorbed to ensure our survival, as there is a huge surface area.
What is a jejunum?
The jejunum is the second part of the small intestine.jejunum means empty
The primary function of the jejunum and ileum is absorption of nutrients into the blood stream?
the mesentery is the thin membrane that helps to hold the small intestine in place. There are a large number of blood vessels in the mesentery, which nourish the small intestine with their blood supply.
What are the structure adaptive features which make the small intestine efficient for absorption of digested food?
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
Which structure located on the walls of the ileum form lymphocytes?
villi
