The Digestive System
The Mouth


The digestive system starts at the mouth.
Salivary glands make food easy swallow.
The Epiglottis prevents food from going
to the lungs.
The esophagus is a tube that carries
food to the stomach.
Esophagus
The esophagus is a muscular tube that
carries stuff from the throat to the
stomach.
 The esophagus uses peristaltic movement
to transport stuff to the stomach.

Stomach
The stomach is connected to the
small intestine.
 The stomach has acid that break
down food.
 The stomach’s inside wall is
protected by mucus.

Gall Bladder
The gall bladder stores minerals, salts, and
water.
 The minerals, salts , and water is taken
from the liver.
 It’s turned into mucus and released to the
stomach.

Small and Large Intestine


The small intestine makes food
less acidic so it can be taken into
the blood.
The muscles of the small
intestine move food in one
direction.
The large intestine helps digest
the food.
The waste is then transported
through the large intestine and
out the rectum.
Rectum

rectum pushes the waste to the anus. The
Anus

The anus gets rid of waste.
How food goes through the body
After the food goes through the
body

After food goes through the body ,if you’re
pody trained, it goes into the toilet.
Hopefully.
Why you shouldn’t take us off ,you
should take the excretory system.



We make eating
possible.
If we didn’t eat we
would die
We can get rid of
liquid too


The excretory only
gets rid of liquid.
Humans could live
without the excretory
system

It takes about 24 hours, depending on what food
it is, for food to be digested.
We make 1 to 3 pints of saliva a day.
An adults esophagus (or gullet) is 10 to 14
inches long and 1 inch wide.
An adult stomach can hold up to 1.5 liters of
food.
Thanks to the esophagus food will get to the
stomach even if we were on our heads.
More fast facts, sorry we ran out of
room on the last slide
The juices that the stomach produce are
acidic.
 The stomach would digest itself if there
wasn’t a wall of mucus protecting it.
