What happens when you eat a
Hershey Kiss?

Stage #1 and #2- The
Mouth and the
Esophagus
When the kiss enters your
mouth both chemical and
mechanical digestion occur.
Your teeth are the mechanical
by grinding up the kiss into
smaller pieces.
Then the saliva (chemical)
attacks the chocolate and
dissolves it.
Together they both create a
bolus.
•
•
•
Your pharynx then pushes down
the bolus into your esophagus.
Your esophagus (throat) uses
peristalsis (involuntary muscle
spasms) to push the food down
into the stomach.
Peristalsis takes about 6-10
seconds.
Stage #3- The Stomach
•
•
The stomach churns the kiss to
make it into smaller bits.
Then the gastric juices that
contains enzymes and
hydrochloric acids and pepsin
which helps break the kiss into
proteins and it also kills bacteria
that might be harmful.
Stage # 4- The Small
Intestine
• After the Hershey kiss leaves
the stomach, it enters the
small intestine.
• When the food is in the
small intestine the nutrients
get absorbed by little finger
shaped objects called villi.
• The nutrients go into your
blood stream so they can
travel to all your bodies cells.
• Small intestines
Stage #5- The Large
Intestine
•
•
The Large Intestine dries out
anything undigested by taking
out all of the water.
The kiss then is then
transformed into waste.
•The kiss reaches the rectum and then the anus.
•The waste is then eliminated from the body.
The Quiz
1. How does mechanical and chemical digestion occur
in both the stomach and the mouth.
2. What organs of the digestive system system are
NOT used during the path and dig estion of food?
3. Where does most of your digestion take place?
4. About how long is the Large Intestine?
The Answers
1. Mouth
• Teeth grind the food up into smaller bits.
• Saliva dissolves to break up food.
Stomach• Muscles contract to grind up food up MORE.
• Acids attack.
2. Liver, gallbladder, and the pancreas.
3. Small Intestine.
4. Five Feet
