The document provides information about the digestive system through various learning activities. It includes a board game called "Tummy Puzzle" that simulates food moving through the digestive system. It also describes the "Gutsy Game", which uses game pieces to demonstrate how food is broken down and absorbed. The main parts and functions of the digestive system are outlined, including the mouth, esophagus, stomach, small intestine, large intestine, and rectum. Various diagrams and processes like mechanical and chemical digestion are also explained. Students are challenged to create a comic strip or infographic telling the story of a food item's journey through the digestive system.

3. TUMMY PUZZLE

4. • This activity is a board game that needs at least
two players.
• The game demonstrates the flow of food into
our digestive system.
• The first one to reach the finish tile wins!
GUTSY
GAME

5. GUTSY GAME!
MATERIALS NEEDED:
Game board
A piece of cube dice or six-
sided small box with numbers 1
to 6
Playing token (e.g., pebble,
button, etc.)
OBJECTIVES:
After performing this activity, you
are expected to:
1. Identify the parts that compose
the digestive system; and
2. Describe the function of each
organ.

6. Procedure:
1. Find someone whom you can play the board game with.
2. Choose a playing token for you and your playmate; place
your tokens on the board’s starting line.
3. Take turns in rolling the dice.
4. The number on the dice tells the number of boxes you may
move your token.
5. Should your token land on a box with instructions beside it,
execute the instructions.
6. The player who first makes it all the way throughout the
digestive system and down to finish line wins the game.

7. GUIDED QUESTIONS:
1. What does the playing token represent?

______________________________ .
2. What do the boxes on the game represent?
________________________________________________
___________________________ .
3. What do the instructions beside the boxes tell you about the
digestive system? ___________

9. 2 main types of digestion
Mechanical digestion
Chemical digestion

10. It is the process thatinvolves

It occurs mostlyin thesmall intestine
whereseveraldigestivejuices, pancreatic
juice, andbile aid in thechemical
digestionof food. Absorption is the
process of passing thesoluble food
moleculesin the wall of the smallintestine
throughthe villi – the tiny, finger-like
projections from theepithelialliningof the
intestinalwall.
PROCESS OF DIGESTION
It is the journeyof
taking in food or any
substanceinto the
body throughthe
mouth.
It is the movementof digested food
nutrients into the blood vessels of the small
intestine through diffusion and use of
nutrients into the body cells through the
microvilli
It is the releaseof undigested food collected in the
rectum called feces and pushed out of the body
through the anus by defecation.

14. A picture is worth a thousand words

15. LET US TRY
THIS!

16. 1. This is where the food is
mechanically broken down by
chewing chewed pulp and the tongue
helps in pushing the bits and broken
into small pieces for easier digestion.
In here, the saliva softens the food to
of food into the pharynx.

17. 2. It reabsorbs water
from undigested food
materials coming
from the small
intestine.

18. 3. It is where the waste or
remaining food materials that
become more solid known as
feces will be temporarily
stored and eliminated

19. 4. It is a tube that connects
the mouth and stomach. It
carries the food down to your
stomach for temporary
storage and further digestion.

20. 5. The food is mixed with
intestinal juices which
contain enzymes that help in
digestion. It is where the final
digestion and absorption of
nutrients happen

21. 6. J-shaped organ found at
the end of the esophagus on
the upper left side of the
abdomen or abdominal cavity
that produces gastric juices
and acids.

23. I Create You Gullet!
Directions:Create a comic strip of digestive processon a sheet of bond paper based on the
situationbelow. Put a title of yourcomic strip on one square.Make ten more squaresfor your story.
Each square shall showboth drawings and words to tell yourstory. The followingterms and concepts
should include in your comic strip:
● Mechanical digestion ● Stomach● Chemical digestion ● Small intestine ● Mouth ● Villi ● Saliva
● Large intestine ● Esophagus ● Rectum ● Peristalsis ● Anus
Situation: Imagine that you are a piece of food (bread,pizza, mango, etc.) that is about to be
eaten by a human being! As you journey through the digestive system, starting from the first bite
and ending with your exit from the human body, you are able to meet the differentorgans and
enzymes that interact with you.

24. EXTENSION ACTIVITY
Directions: Create an infographic of the digestive system - parts
and functions as well as the disorders that you might be getting
from malfunctionof some organs of the system. Note: An
infographic is a collection of images, diagrams, and text that
provides an easy-to-understand general idea of a topic. Most
infographics use prominent and attractive illustrations to
converse the facts quickly and clearly.
