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 :)

List 2 ways the ileum adapted role in absorption?
1)Villi and micro villi increase the surface area for the absorption of digested food. 2)Epithelial cells lining the intestine have a high volume density of mitochondria, meaning lots of energy for the active uptake of digested food. :)
The greatest amount of absorption in the small intestine takes place in the?
Actually the Complete Absorption takes Place in the small intestine .It contains Finger likeprojections called Micro villi these run through the small intestine which increases thesurface area for absorption.
Where is the jejunum located in the human body?
In adults the jejunum is found in the small intestine and lies between the duodenum and the ileum. The lining of the jejunum absorbs small food particles which have previously been digested in the duodenum.
What is the function of the iieum?
The ileum is a very long part of the small intestine. After protein digestion in the stomach and starch digestion in the mouth, the ileum releases many enzymes to digest the remaining products of starch hydrolyis (which are sugars). The ileum has many infoldings along its length called villi (singular villus) which increase the surface area for absorption of the most important products of digestion; glycerol, glucose and amino acids.
Why do humans not have a caecum?
Yes they do - herbivores such as horses have much larger caecums that ferment and digest plant fibre. Carnivores have much smaller ones Humans have a caecum which is a small pouch it lies at the section between the small and large intestine. (the illeum and colon) the illeocecal valve stops fluid flowing back into the smallintestine.

Which nutrient is digested in the ileum?
Nothing is digested by the liver in the digestive system at all. So there is basically no answer to it.
What does the ileum do?
The ileum is the end of the small intestine it basically absorbs digested material through its wall which enters into the bloodstream.
What structure provides a large surface are for absorption in the ileum?
microvilli
If the third stage of digestion is absorption which begins when food enters the?
The jejunum or ileum of the small intestine.
What is the difference between the Ileum and the Duodenum?
Distinguishing feature of the duodenum are the Brunner's glands, whereas the Peyer's patches make the ileum easily identificable. The common bile duct and the pancreatic duct enter the duodenum, whereas the ileum does not receive duct from other organs. Outermost layer of the duodenum is comprised of adventitia as it is located retroperitoneally, while the outermost layer of the ileum is represented by serosa(mesothelial cell are evident). The ileum has also more goblet cells than the duodenum. Duodenum represents major site of iron absorption, while the ileum-B12 absorption.
Where is food digested the most and taken into the body?
Most digestion and absorption takes place in the small intestine.Initial and substantial digestion takes place in the stomach, before being completed in the upper part (duodenum) of the small intestine. The middle part of the small intestine (jejunum) is where most absorption of nutrients occurs, with the remainder done in the final part (ileum), and in the large intestine.
What is villi and what important structures do they contain?
these are in the ileum wall in the small intestine and they are rsponsible for absorption of nutrients into the bloodstream
Absorb food and pass it into bloods vessels from the ileum?
In the Small Intestine there are three section that are responsible for digestion and nutrient absorption. The first section is called the duodenum. The duodenum is manly responsible for the digestion of food. The second section is called the jejunum. The jejunum is the primary site of nutrient absorption. The third section is called the ileum. The ileum is the section that absorbs the nutrients that the jejunum missed.

What is the portion of the small intestine that performs most absorption?
Small intestine is about 20 feet long. It has jejunum and ileum as two part. Out of these distal part of ileum absorbs most of the fluid and nutrients.
What does the jejunum digest?
the portion of the mammalian small intestine that follows the duodenum and precedes the ileum that is the function of absorbing digested food
