Here are 3 key healthful practices to maintain a healthy digestive system: 1. Eat a balanced diet with plenty of fiber. Fiber helps food move through your system smoothly. Good sources include fruits, vegetables, whole grains. 2. Stay hydrated. Drinking enough water is important for digestion. Water helps transport nutrients and waste. 3. Manage stress. High stress levels can disrupt your digestive health. Try relaxation techniques like deep breathing, yoga or meditation.

3. OBJECTIVES:
Learning Competency:
Explain ingestion, absorption,
assimilation and excretion (S8LTIVa-

a. Identify the organs that make up
the digestive system
b. Give the function of each organ

20. Digestive System Organization
• Gastrointestinal (Gl) tract

21. When you see foods what
is your reaction?

22. What have you observed
from the video presented?

23. What happens when the
food enters our body?

24. How the process of
digestion occurs?

25. What will happen to the
particles that are not
absorbed in the small
intestines?

26. Why is it we feel
pain when there is
no food intake?

27. DIGESTIVE SYSTEM
Is the system responsible for breaking down
the food particles and gives nutrients to the
different parts of the body. It is a complex
process of turning the food you eat into
nutrients which our body uses for energy,
growth and cell repair needed to survive.

28. FIVE STAGES OF DIGESTION
1. INGESTION- It refers to the
entry of food into the
alimentary canal through the
mouth.

29. FIVE STAGES OF DIGESTION
2. ABSORPTION- is the process by which
digested food nutrients and water are taken from
the intestine and moved throughout the body.

30. FIVE STAGES OF DIGESTION
3. ASSIMILATION - is the movement of
digested food molecules into the cells of
the body where they are used.

31. FIVE STAGES OF DIGESTION
4. EXCRETION- the process of removing
wastes and excess water from the body. The
excretion in the digestive system works with
the excretory system to excrete or eliminate
the waste product of our body.

32. DISSECTION OF A FROG

33. A GUTSY GAME
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!
Objectives:
After performing this activity, you are expected to:
Identify the parts that compose the digestive system;
and Describe the function of each organ.

34. 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.)
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.
The player who first makes it all the way throughout the digestive system and
down to finish line wins the game.

35. Study the figure below and answer the questions that follow.
Questions:
