The small intestine lies between the stomach and large intestine. It receives bile and pancreatic juice to aid in digestion, and is the site where most absorption of nutrients occurs. It is very long, over 20 feet, to allow sufficient time for digestion and absorption. The small intestine has three parts - the duodenum, jejunum, and ileum - which progressively absorb nutrients. The large intestine is wider than the small intestine and absorbs water before waste is stored in the rectum and expelled through the anus.

2. or is an
organ in the gastrointestinal tract
where most of the absorption of
nutrients from food takes place.
 It lies between the stomach and
large intestine, and receives bile
and pancreatic juice through the
pancreatic duct to aid in digestion.
 it is actually the longest section of
your digestive tube,
measuring about 22 feet (or seven
meters) on average, or three-and-a-
half times the length of your body.

3. Three parts of the small intestine
– completes the first
phase of digestion of food from the
stomach. The digested food is
mixed with enzymes from the
pancreas and bile from the
gallbladder. The enzymes and bile
help break down food.
- is to absorb sugars, amino acids, and fatty
acids.
- absorbs any remaining nutrients that did not get
absorbed by the duodenum or jejunum, in particular vitamin
B12, as well as bile acids that will go on to be recycled.

4. The muscles of the small intestine mix food with digestive
juices from the pancreas, liver, and intestine, and push the
mixture forward for further digestion. The walls of the small
intestine absorb water and the digested nutrients into your
bloodstream.

5. - is much
broader than the small
intestine and takes a much
straighter path through
your belly, or abdomen.
> Is larger in diameter but
shorter than the small
intestine.
> It absorbs water and
salts from the material that
has not been digested as
food, and get rid of any
waste products left over.

6. - a pouch
connected to the
junction of the small and
large intestines.
 Its function is to aid in
digestion.
 It receives digested
materials from the
small intestine, and it
pushes these materials
into the ascending
colon.

7. - removes water and some
nutrients and electrolytes from
partially digested food. The
remaining material, solid waste
called , moves through the
colon, is stored in the rectum, and
leaves the body through the anus.
The is part of the digestive
system.
is the last section
of the bowel . It's about a foot and
a half long and is shaped like the
letter “s.” Its job is to hold feces
until you're ready to go to the
bathroom.
- is the lower
end of your large
intestine, the
rectum, stores stool until
it pushes stool out of your
anus during a bowel
movement.

8. :
a. the upper part, with longitudinal
folds called rectal columns
b. the lower portion, with internal
and external constrictive
muscles (sphincters) to control
evacuation of feces
c. and the anal opening itself.
- is the opening at the far
end of the digestive tract through
which stool leaves the body.

9. The large intestine is one of the many important parts of your
digestive tract. This is a series of organs that starts with your
mouth and ends with your anus, the opening of your rectum.
The food that you eat passes from your mouth through your
esophagus to your stomach. It then goes from your stomach to
your small intestine. These organs break down food into bits
that your body absorbs and uses for energy. By the time the food
you eat gets to your large intestine, most of the digestion is
done. The large intestine is also called the colon and the large
bowel.
The job of your large intestine is to absorb water, minerals, and
some of the remaining nutrients from your food. It will change
the leftover waste into a bowel movement. This is also called
stool. Your rectum stores the stool until you feel the need to
have a bowel movement. Muscles of your rectum then push the
stool through your anus and out of your body.

10. The hollow inside of your large intestine is known as the lumen.
Its lining is called mucosa. It has special folds and projections to
help it absorb nutrients. A layer of muscle (muscularis propria)
supports the walls of your large intestine.
1. Begin regular screening for colon cancer at age 50.
2. Maintain a healthy weight.
3. Exercise regularly.
4. Include lots of fiber, vegetables, fruits, and whole
grains in your diet.
5. Stay hydrated and drink plenty of water each day.
6. Cut back on red meat and processed meats such as
cold cuts, hot dogs, and sausages.
7. Don't smoke. Drink alcohol only in moderation.

11. 2. Bloating - belly feels swollen after eating
- when bowel movements become less frequent
and stools become difficult to pass.
- is frequent, loose, and watery bowel movements.
