These are slides to teach Year 7 (Lower Secondary) about Respiratory System in Humans

1. JOURNEY TO
THE WEST
Human Respiratory System
Year 7

2. What is respiratory system?
System that is responsible for taking in oxygen that body cell
needs from the outside, and to throw away the waste products
and carbon dioxide produced by those cells.
Consists of:
Nose --- Pharynx --- Larynx --- Trachea --- Bronchus --- Bronchiole --- Alveolus
Lung (Pulmo)

3. STARTER ACTIVITY!
- What changes that you can observe?
- What makes that changes to happen?
- Discuss with your friends and state your
conclusion!
Your teacher will guide you to do something coOoOool… and after that, try to answer
these series of questions!

4. RESPIRATION REACTION

5. RESPIRATION REACTION
Because it is requires oxygen, this type of respiration is called
by AEROBIC.
Are
respiration
and breathing
the same?

7. RESPIRATORY SYSTEM

8. 1 NOSE
Air enters the passage through the nose.
Fine hairs in the nose trap dust particles in the
air.
The nose is moistened by mucus (a watery
liquid)
● To make the air moist as it passes inwards
● To traps bacteria that are carried on the air
currents
The air is warmed by the body temperature

9. 2 PHARYNX
Serves as a passageway for air and also food
(from digestive system)
Aids in phonation by changing its shape.
3 LARYNX
Specific passageway for air from the pharynx
(food DO NOT allowed here!)
Contains vocal cords, which produce sound.

10. 4 TRACHEA (WINDPIPE)
A smooth, muscular tube leading from the
larynx to the bronchus
It is made from rings of cartilage.
Each ring is in the shape of a “C”, act as
structure support.
The inner lining of trachea has 2 types of cells:
● Mucus-secreting cells
To trap the dust particles and bacteria in the form of
mucus
● Ciliated epithelial cells
Move the mucus to the pharynx where it enters the
back of the mouth and it is swallowed.

11. 5 BRONCHUS
The trachea divides into two
smaller tubes, known as bronchi
(singular : bronchus).
These tubes still lined up with
cilia and mucus on their inner
surface.
… And finally we made our way to lungs!
The bronchi divide up into
many smaller tubes, called
bronchioles.
This is the last tube before the
air goes to the end of breathing
journey: alveolus.
6 BRONCHIOLES

12. 7 ALVEOLUS
… And finally we made our way to lungs!
The lungs are two spongy organs that filled with an
interlacing network of tubes, alveoli sacs, and
blood vessels
Each lung is divided into lobes;
the right lung into 3 lobes and the left lung into 2.
The air cells where the gas exchange takes place.
An alveolus has adaptations to allow it to exchange
gases effectively.
● Large surface area
● Thin and elastic walls
● Surround by a network of blood capillaries
● Moist surface

13. ANOTHER STRUCTURAL SUPPORT
INTERCOSTAL MUSCLE
The internal and external intercostal muscles
make the ribs move.
DIAPHRAGM
It is a large sheet of muscle attached to the
edges of the tenth pair of ribs and the
backbone.
It separates the chest cavity (lungs & heart)
from the lower body cavity.

17. YOU CAN DIVIDE THE CONTENT
Venus has a beautiful name
and is the second planet from
the Sun. It’s hot and has a
poisonous atmosphere
Mercury is the closest planet
to the Sun and the smallest
one in the Solar System—it’s
only a bit larger than the
Moon
MERCURY VENUS

18. HERE ARE THREE IMPORTANT IDEAS
Mercury is the closest
planet to the Sun and
the smallest of them all
Venus has a beautiful
name and is the second
planet from the Sun
Despite being red, Mars
is actually a cold place.
It’s full of iron oxide dust
MERCURY VENUS MARS

19. DIVIDE THE CONTENT IN FOUR
Mars is actually a very
cold place
Venus has extremely
high temperatures
Jupiter is the biggest
planet of them all
Saturn is a gas giant
and has several rings

JUPITER
VENUS
SATURN

20. Venus has extremely
high temperatures
Neptune is the farthest
planet from the Sun
REVIEWING CONCEPTS

21. AWESOME
WORDS

22. “This is a quote, words full of wisdom
that someone important said and can
make the reader get inspired”
—SOMEONE FAMOUS

23. A PICTURE
IS WORTH A
THOUSAND
WORDS

24. A PICTURE
ALWAYS
REINFORCES
THE CONCEPT
Images reveal large amounts of data, so
remember: use an image instead of a
long text. Your audience will appreciate
it

25. 98,300,000
Big numbers catch your audience’s attention

26. Jupiter’s rotation period
9h 55m 23s
333,000
The Sun’s mass compared to Earth’s
386,000 km
Distance between Earth and the Moon

27. LET’S USE SOME PERCENTAGES
Mercury is the closest
planet to the Sun and
the smallest of them all

Venus has a beautiful
name and is the second
