How is small intestine adapted for absorption of food?

Answer 1

The small intestines leads the stuff from the stomach to the large intestine, it is very long and has a large surface area. At the start, as food exits the stomach, bile is added to the mixture and this helps to break down more of the food into its chemical constituents. As the food passes down the small intestine by muscular movements called peristalsis, the chemical are absorbed by the small intestine and go into the hepatic portal vein which joins the small intestine to the liver. When food reaches the end of the small intestine, all the nutrients have been absorbed and in the large intestine water is then recovered and the semi solid stool formed before the waste is excreted.

Answer 2

The main goal is to absorb the food quickly into the blood stream. They do this by increasing the surface area. They have folds and villi to increase it, and on the villi they have smaller villi called microvilli to further increase the surface area.

Answer 3

Its very long (in humans), folded lining to give large surface area, numerous projections called villi, on which are even more microscopic projections called microvilli, which again increase surface area for absorption.

Answer 4

villas are located on it which help absorb the nutrients

Answer 5

OMG so easy ans from book or use brain to think lol.

Answer 6

the villi within the small intestine allow it to absorb nutrients
