LARGE INTESTINE

     Ch 21 NOTES 5/24
   Large in diameter,
    not length

   About 5 feet long
   2 ½ inches wide

   Goes up and
    around outside of
    small intestines
   Inner layer
    produces mucus so
    waste products
    easy to move
    through
   NO villi present
   Peristalsis to move
    food along
FUNCTION
           1. Absorbs water
            (some minerals too)

           2. Eliminates
             indigestible
             materials from
             food
   Ileum of the small intestine enters the
    cecum of the large intestine at the
    ILEOCECAL VALVE
    APPENDIX – small
     protrusion where
     the small and large
     intestine meet.


APPENDICITIS –
inflammation of the
appendix
MAIN DIVISIONS:
1. CECUM – 1st 2 feet

2. COLON
    a. Ascending
    b. Transverse
    c. Descending
    d. Sigmoid

3. RECTUM – last 7-8
   inches
Bacteria are everywhere. We swallow them with
our food, drink them with water, they are in the
air we breathe, on our skin, in our mouths,
digestive tract, sinuses and other areas of our
bodies.
In so far as health is concerned, some of them
are harmful, some neutral and some are very
beneficial. Some are extremely valuable for good
health as they work harmoniously with our
immune system. In a healthy colon, there are
literally billions of beneficial or "friendly"
bacteria.
Under favorable conditions, they multiply at a
fast enough rate to keep pace with the large
numbers that are lost during elimination.
Bacteria is also referred to as micro-organisms.
When they are located in the intestinal tract,
they are referred to as "intestinal flora,"
"micro-flora", "good bacteria",
"friendly/beneficial bacteria" or sometimes
just "flora."
These friendly bacteria synthesize many
important vitamins in the digestive tract
including Vitamin K and some of the B
vitamins.
A very important function they perform is
helping the colon maintain a proper pH or acid-
base balance. It is necessary for the pH to stay
in the correct range in order for other health
supporting bacteria to exist. It is also
important to keep levels of antagonistic micro-
organisms under control.
PROCESS
   Bacteria break
    down some
    remaining foods
    (mostly plant)
   Release methane
    and hydrogen
    sulfide
   Makes odor of
    feces and “gas”
    (flatus)
Plant cell walls are hardest for our body
  to break down. Bacteria in the large
  intestine try to break it down – work
  extra

Make more of their waste product,
 methane, so we have more gas
   Bacteria also make
    vitamin K

   Help the body to
    absorb nutrients
    better
FECES
   Solid waste product of food

   Consists of undigested food, mucus,
    bacteria, and some water
   When walls in the rectum stretch
    due to feces entering, it sends a
    message to the brain and walls of
    rectum start to contract.

Called a “bowel movement”
   Anal canal – last
    inches of the rectum

   End of the rectum has
    2 sphincters – one
    you can control

   Defecation – the
    elimination of feces
HEMORROIDS
Enlarged veins of the anal canal
proc·tol·o·gy
 The branch of medicine
 that deals with the
 diagnosis and treatment
 of disorders affecting the
 colon, rectum, and anus.
   FIBER in the diet
    increases strength
    of colon
    contractions and
    softens stool for
    easier elimination
   DIARRHEA – watery stools

     - food wastes are rushed through
    the large intestine before it has time
    to absorb water
      - usually caused by bacteria

PROBLEM – causes dehydration
   CONSTIPATION – feces hard to
    eliminate

     - food wastes remains too long in
    the body, stools hard

Caused by lack of fiber or “holding it”
