  • Large Intestine
  • The liver, gall bladder, and pancreas add enzymes
    to the food traveling from the stomach

4
Mouth
  • The mouth is the first stage of the digestive
    system.
  • The saliva helps soften the food up so you can
    swallow.
  • The teeth chew the food to make it smaller so you
    can swallow without choking

Esophagus
  • The esophagus is the organ into which the
    swallowed food is pushed.
  • It connects the throat above with the stomach
    below.
  • At the junction of the esophagus and stomach,
    there is a ring like valve closing the passage
    between the two organs.
  • However, as the food approaches the closed ring,
    the surrounding muscles relax and allow the food
    to pass.

7
Stomach
  • The stomach has acid that helps digest the food.
  • Muscles in the stomach
  • After this the food is separated it goes into the
    small intestine.

8
Small Intestines
  • It is part of the Gastrointestinal tract between
    the stomach and the large intestines
  • It is where most of the digestion takes place
  • It is made up of 3 parts
  • Duodenum
  • Jejunum
  • Ileum

9
Large Intestines
  • AKA the colon
  • Last part of the digestive system
  • Takes 12-25 hours to complete digestion
  • Absorbs remaining water from indigestible food
    matter
  • Stores unusable food matter (waste)
  • Eliminates waste from the body through the rectum
