Question

How is small intestine designed to absorb food explain how the fats are digested in our body?

Answer 1

Answer:

Explanation:

the wall of small intestine are covered with finger like extensions called  VILLI(plural). each villus (singular) has microvilli  that help in absorption of food material by increasing the surface area.  these villi are richly supplied by blood vessels , as the nutrients were get diffused to these vessels  and transferred through out the whole body in order to repairment of old tissues and for other metabolic activities.

      when fat reach duodenum  the the large fat globules were get break into smaller fat globules by the action of bile juice , this process is called as emulsification of fat . then, when these smaller fat globules reach ileum of  small intestine then  the walls of ileum  secret intestinal juice that is succus entericus that finally convert these fat globules into fatty acid and glycerol. in this way the digestion of fat get completed .

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.

===>>.. The three major classes of nutrients that undergo digestion are proteins, lipids (fats), and carbohydrates.

===>>Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine.

===>> As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules.

===>>Also It Important That The Digestive Processes. The processes of digestion include six activities: ingestion, propulsion, mechanical or physical digestion, chemical digestion, absorption, and defecation.

===>>The first of these processes, ingestion, refers to the entry of food into the alimentary canal through the mouth.

====>>Unlike the small intestine, the large intestine produces no digestive enzymes. Chemical digestion is completed in the small intestine before the chyme reaches the large intestine.

===>>Functions of the large intestine include the absorption of water and electrolytes and the elimination of feces.
