9. The Digestive System
and its Part and their
Function

11. OBJECTIVES
Identify the parts of the Digestive
System and describe their
function.

12. THE GUTSY GAME

13. Q1. What do the tokens represent?
The tokens represent the food that
was eaten
Q2. What do the spaces on the board
represent?
The spaces on the board game represent the
different organs or structures of the
digestive system

14. Q3. What do the spaces on the board game
represent?
The directions on some of the spaces describe the
different physical and chemical conditions that
affect proper functioning of the digestive system
Q4. What do the directions on some of the
spaces tell you about the digestive system

15. The digestive systems of different
representative species of animals are
similar to each other in that they are
all made up of a continuous tube
with two openings: the mouth and
the anus

17. Digestion
Digestion is the breakdown of large
insoluble food molecules into small
water-soluble food molecules so
that they can be absorbed into the
watery blood plasma.

18. Parts
 mouth
 Esophagus
 Stomach
 Small Intestine
 Large Intestine
 Gall bladder
 Liver
 Pancreas
 Anus
 rectum

19. MOUTH
Ingestion takes place
It is where the teeth physically break down
food by chewing and with the saliva which
lubricates the food.

20. Esophagus
A long muscular tube that squeezes the food
and connects the mouth to the stomach
The muscular contractions of the esophagus is
called peristalsis

21. PHARYNX
Located at the back of the mouth cavity
its muscular walls function in the process of
swallowing, and it serves as a pathway for the
movement of food from the mouth to the
esophagus.

22. STOMACH
 A storage tank for digesting food by mixing it with powerful
acids to kills bacteria and break down starchy foods
 Protein digestion begins
 Food remains in the stomach for 3 hours where it physically
broken down by churning muscular contractions of the
stomach wall muscles.

23. SMALL INTESTINE
 Long tube that is about 7 m long and 2.5 cm in diameter
 Digestion finishes up here and all the nutrients are absorbed
into the blood through the villi.
 3 parts
 Duodenum
 Jejunum
 ileum

24. LARGE INTESTINE
Takes up any left over water, vitamins and
electrolytes ( like sodium and chloride) in food
waste.
Thicker in diameter than the small intestine
Mucus lubricates the feces

25. RECTUM
Storage area for feces at the end of the large
intestine
There is a sphincter surrounding the anus, the
hole through which feces passes on defecation.

26. Accessory Parts

27. LIVER AND GALL BLADDER
 Produces bile to break down fats, cleanses blood and
changes nutrients into forms the body can use and store
 Converts simple sugar into glycogen
 Gall Bladder- It is where bile is temporally stored

28. PANCREAS
Produces alkaline substance which is secreted
into the duodenum to neutralize the stomach to
make food nutrients less acid.
Breaks down food chemically

29. Salivary Gland
Produces saliva that moisten the food in the
mouth
 contains enzymes that breaks down starchy
food like bread

30. APPENDIX
It is located in the right iliac region of the
abdomen (in the lower right-hand abdominal
area), measuring about four inches

31. FUNCTIONS OF THE DIGESTIVE SYSTEM
Digest the food we eat
Take the nutrients out of your food
so your body can use it

32. “PERFECT MATCH” ACTIVITY

33. What are the parts of the Digestive
System? Give their function.

34. Why is properly chewing of food in the
mouth is essential or important in the
movement of food to the stomach?

35. ASSIGNMENT
EXPLAIN THE PROCESS OF
DIGESTION.
