(a) Where does digestion of fat take place in our body?
(b) How is small intestine designed to absorb digested food?
Answers
Answer:
small intestine
Explanation:
small intestine with the help of bile juice.
small interstine has many tiny finger-like structures of tissue called villi. this helps in absorbing dijested food. small intestine is good for absorption since it has a large inner surface area.
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.
==>Bile emulsifies (breaks into small particles) lipids (fats), which aids in the mechanical digestion of fats. The pancreas and gland cells of the small intestine secrete digestive enzymes that chemically break down complex food molecules into simpler ones.
==>... When food passes through the duodenum, digestion is complete.Most chemical digestion takes place in the duodenum by chemicals secreted by the liver, pancreas and small intestine.
==>The other two sections of the small intestine, the jejunum and the ileum, absorb food molecules by way of the villi directly into the blood stream.
==>The pyloric sphincter controls the flow of chyme from the stomach into the small intestine.
==>We previously learned that the pyloric sphincter controls the flow of chyme as it passes out of the stomach and into the small intestine. Chyme is the name given to the partially digested food mass.
I hope it helps you
