Question

how is the small intenstine designed to absorb digested food

Answer 1

The inner surface of small intestine has millions of small finger like projections called villi, which increase the surface area for absorption of food. The villi are richly supplied with blood vessels which take the absorbed food to each and every cell of the body.

Answer 2

hi mate,

==> we know that the the small intestine has millions of tiny finger-like projections called villi. These villi increase the surface area for more efficient food absorption. Within these villi, many blood vessels are present that absorb the digested food and carry it to the blood stream.

==> and also we know that the food breakdown into glucose and then the cerb's cycle reaction takes that is given in the book class 10 bio and the rest material move in small intestine small villi like projection aborb the nutrients and that are absorb by cell and the cellulose of food which is indigested expelled out.

==> Digestive juice produced by the small intestine combines with pancreatic juice and bile to complete digestion.

==> The body completes the breakdown of proteins, and the final breakdown of starches produces glucose molecules that absorb into the blood.

===>>The small intestine, despite its name, is the longest part of the gastrointestinal tract.

==>> It works with other organs of the digestive system to further digest food after it leaves the stomach and to absorb nutrients.

I hope it helps you
