PUZZLE
Thank you. Tr. Warren. Okay class.
Don’t return to your seats just yet.
Let’s do another activity. Here are 5
envelopes.
Choose one representative of your
group and proceed in front.
Choose one envelope. Then proceed
to your respective groups.
Now,open your envelopes and
identify the specific image and
discuss its function in 3minutes.
Okay, time is up! What have you
noticed with the pictures?
Yes. You have learned the following
parts in your previous year. Now will
(5 Students approaches in front)
(Students return to their groups with own envelopes)
(Student discussion)
They are parts of the digestive system.
5. discuss the Digestive process in
detail. So with that what is the
function of the digestive system?
Yes. The digestive system Is
responsible for breakdown and
absorption of nutrients from food
thereby bringing energy for the
body. So now, One representative
per group willdiscuss their
collaboration in front. Who among
you have the mouth image?
Okay! Be the first to discussyour
work.
Good job! Yes!
The mouth breaks down food into
bits to facilitate transfer thru the
esophagus to the stomach.This is a
process called mastication. It also
servesas the initial stage of
digestion with the enzyme
converting carbohydrates. What is
that enzyme?
The system responsible for food after we eat isDigestive
System.”
We have have it!
The mouth offers an entry of food into the body. It is also
where the mechanical breakdown begins.
Salivary amylase!
And now let’s follow the food as it
passes through the digestive system.
From the mouth, food passes
through the? What connects the
mouth and stomach?
Yes. And who have the esophagus?
Can you share your ideas?
That’s correct! So what do we call
that rhythmic movement?
Esophagus!
The esophagus transact food from the mouth to the
stomach by a movement.
Peristalsis!
That’s right. So through peristalsis,
the food,or now called chyme, goes
through the cardiac sphincter, a
ring-shaped musclewhere food
enters from esophagus to stomach
that prevents food reflux. The food
then is transported to the stomach.
So again, what is that muscle that
6. prevent reflux?
Correct. Now, whichgroup now
hold the stomach? Can you discussit
in front?
Yes that’s correct. Now,where does
the food go after passing the
stomach?
Now who among you the small
intestine picture? Please go in front
and discuss.
Yes, that’s correct. You may return
to your seat. Furthurmore in the
small intestine, bile acts on the food.
Bile is produced in the liver and
stored in the gallbladder. It break
down fats into smaller droplets.
What organ produces bile?
How about the one that stores bile?
The cardiac sphincter!
The stomach further forms the food into smaller portions
and contains HCl that aids digestion and destroys the
bacteria present in the ingested food. It also has pepsin the
breaksdown protein into smaller forms.
Small intestines!
The small intestine is where pancreatic juices aids in
digestion of protein, carbohydrates and fats. It is also the
longest part of the digestive system.
Liver!
Gallbladder!
That’s correct! Small intestinesthe
remains of the digestion and
absorption are now enters the large
intestine who happens to be in the
last group.
Yes, that true. You may now return
to your seat. The large intestine is
composed by the ascending,
transverse and descending colon,
the appendix, anus and rectum. It is
alsowhere absorption of water
occurs. The remains after water has
been absorbed are now called
STOOL or FECES then it willbe
stored in the rectum then excrete to
The large intestine is composed by the ascending,
transverse and descending colon, the anus and rectum. It is
also wherethe appendix is. It also contains the feces ready
for excretion.
7. the anus.
So in summary, the digestive system
is composed of?
All are whichfunction to do what?
Very good! So now, I willturn you
over to Tr. Rose for the next activity.
The mouth, esophagus, stomach, large and small intestines!
They are responsible for breakdown and absorption of
nutrients from food thereby bringing energy for the body.
