What is the Digestive System?
•
•
•
•
The digestive system is made up of the
digestive tract
A series of hollow organs joined in a long,
twisting tube from the mouth to the anus
These organs help the body break down
and absorb food
Why is it Important?
1. When you eat foods they are
not in a form that the body can
use as nourishment.
2. Food and drink must be broken
down!
3. Digestion is the process by
which food and drink are broken
down so the body can use them
for energy.
How is food digested?
•
Digestion involves mixing food with digestive juices
to keep making it smaller so the body can absorb it
for fuel!
What are these juices like?
Wait...I thought it was just the
stomach!
The digestive system is made up of these
organs/structures:
1. Mouth
2. Esophogus
3. Stomach
4. Liver, Pancreas,
& Gallbladder
5. Small Intestine
6. Large Intestine
7. Colon
8. Rectum/Anus
IN THAT ORDER!!!
MOUTH & ESOPHAGUS
Mouth- The mouth chews food
to break up the large
pieces to swallow and
creates saliva to make it
softer to swallow.
Esophagus- A long tubelike structure that propels
the food from the mouth to
the stomach.
STOMACH
The stomach has three
main functions:
1. Store the food
2. Mix the food up
3. Slowly empty into
the small intestine
Just like a cement mixer!!!e
Small and Large Intestine
What is absorbed
here?
About 30 feet combined!!!
