2. RESPIRATORY
SYSTEM
Your respiratory system is made
up of your lungs, airways (trachea,
bronchi and bronchioles),
diaphragm, voice box, throat, nose
and mouth. Its main function is to
breathe in oxygen and breathe out
carbon dioxide. It also helps
protect you from harmful particles
and germs and allows you to smell
and speak.

3. WHAT IS RESPIRATORY
SYSTEM?

4. The respiratory system is a network of organs and
tissues that enable breathing, which is the process of
taking in oxygen and expelling carbon dioxide.Your
respiratory system is the organs and structures in your
body that allow you to breathe. It includes your lungs,
nose, mouth and the tubelike structures (airways) that
connect them. You also have muscles and blood
vessels that support your respiratory system,and ribs
to protect it. These parts work together to bring
oxygen into your body when you inhale and get rid of
carbon dioxide when you exhale

5. What are the parts of the respiratory
system?
-The main organs of your respiratory system
are your lungs. But your respiratory system
has many different parts that work together
to help you breathe.
ANATOMY:

6. 1.NOSE AND MOUTH: THE ENTRY POINTS
FOR AIR INTO THE RESPIRATORY
SYSTEM.
2. THROAT (PHARYNX): A MUSCULAR
PASSAGE THAT SERVES AS A COMMON
PATHWAY FOR BOTH AIR AND FOOD.
3. VOICE BOX (LARYNX): CONTAINS THE VOCAL
CORDS, WHICH VIBRATE TO PRODUCE SOUND.
4. WINDPIPE (TRACHEA): A TUBE THAT CARRIES
AIR FROM THE LARYNX TO THE LUNGS.

6. DIAPHRAGM: A MUSCLE LOCATED BELOW
THE LUNGS THAT HELPS WITH BREATHING BY
CONTRACTING AND RELAXING.

7. BRONCHI AND BRONCHIOLES: BRANCHES
OF THE TRACHEA THAT LEAD INTO THE
LUNGS AND FURTHER DIVIDE INTO SMALLER
TUBES.
8. ALVEOLI: TINY AIR SACS IN THE LUNGS
WHERE OXYGEN IS TRANSFERRED TO THE
BLOOD AND CARBON DIOXIDE IS REMOVED.
5. LUNGS : The primary organs of respiration,
where gas exchange (oxygen and carbon
dioxide) occurs.
Parts of your respiratory
system include your:

7. GAS EXCHANGE:
Gas Exchange is the lifeline
of respiration and
photosynthesis. Explore
how 5 animals and 5 plants
perform their unique
version of breathung from
lungs and gills to stomata
and roots
Gas exchange is the process
where oxygen and carbon
dioxide move between an
organism and its
environment.

8. GAS EXCHANGE:

9. GAS EXCHANGE METHOD: Skin,Lungs, and
mouth lining.
Frogs utilize a combination of cutaneous
(through the skin), buccopharyngeal (through
the mouth lining), and pulmonary (through the
lungs) respiration for gas exchange.
FUN FACTS: Can hibernate underwater by
breathing throuh skin

10. Reptiles primarily utilize lungs for gas
exchange, relying on the efficient transfer
of oxygen into the bloodstream and carbon
dioxide out of the body. While some
reptiles, like snakes, can reroute
oxygenated blood to other tissues, and
some aquatic reptiles might utilize skin for
limited gas exchange, lungs are the primary
organs for this process in all reptiles.
FUN FACTS: Reptiles are a fascinating group
with unique characteristics and behaviors. For
example, snakes and lizards use their tongues
to smell.
REPTILES:

11. Bird lungs facilitate highly efficient gas exchange due to their unique structure
and the use of air sacs. Gas Exchange: Within the lungs, air flows through tiny
tubes called parabronchi, which branch into numerous air capillaries. These air
capillaries are surrounded by a dense network of blood capillaries.
doves can fly at high
speeds and are known for
their agility in the air.
BIRDS: DOVE
FUN FACTS:

12. Gas exchange in fish primarily occurs in the
gills, where oxygen from the water diffuses
into the blood and carbon dioxide diffuses
out.
FUN FACTS: Fish breathe using gills,
extracting oxygen from the water that
passes over them.
FISH:

13. GAS EXCHANGE: In dogs, gas exchange, the
process of oxygen moving into the bloodstream
and carbon dioxide moving out, primarily occurs
in the alveoli of the lungs
FUN FACTS:
Sense of Smell: Dogs possess a sense of
smell that is 10,000 to 100,000 times more
sensitive than humans.
Sweating: Unlike humans, dogs primarily
sweat through their paws, not their whole
body.

14. Gas Exchange Mangrove trees have
developed unique adaptations for gas
exchange due to their unique
environment. They have aerial roots,
including pneumatophores, prop roots,
and stilt roots, that facilitate oxygen
intake from the atmosphere. These
roots have lenticels, which are tiny
pores that allow for gas exchange
Fun Facts: Mangrove trees dominate
this wetland ecosystem due to their
ability to survive in both salt and fresh
water

SALTWATER SURVIVOR

15. GAS EXCHANGE: Water lilies have a unique
adaptation for gas exchange where stomata
are located on the upper surface of the
leaves.
FUN FACTS: While often associated with
white, water lilies actually bloom in a wide
range of colors, including pink, red, orange,
yellow, purple, and blue.
WATER LILY:

16. Gas exchange in the sampaguita flower
(and all plants) involves the intake of
carbon dioxide and the release of
oxygen, primarily occurring through tiny
pores called stomata on leaves. This
process is crucial for both
photosynthesis and respiration.
How it works:
Stomata: These are small openings,
mostly on the underside of leaves,
that allow for gas diffusion.
Photosynthesis: Plants use carbon
dioxide to create sugars (glucose) for
energy.
SAMPANGUITA:

17. Gas exchange in tomatoes
primarily occurs through
stomata, small pores on the leaf
surface, which regulate the
intake of carbon dioxide (CO2)
for photosynthesis and the
release of oxygen (O2) and water
vapor. Additionally, lenticels,
found on stems, also facilitate
gas exchange.
TOMATOES:

18. Stomata:These pores open and close to control the
movement of gases. When open, CO2 enters the leaf for
photosynthesis, and O2 and water vapor exit. Factors like
light intensity, CO2 concentration, and water availability
influence stomatal opening and closing.
Lenticels:These pores in the stems allow for gas exchange,
particularly oxygen, in woody tissues.
Carbon Dioxide (CO2):A vital component for photosynthesis,
CO2 is absorbed through stomata.
Oxygen (O2):Released during photosynthesis, O2 is also a
byproduct of respiration, a process essential for plant
metabolism.
Water Vapor:Stomata regulate the release of water vapor
through transpiration, which can be influenced by
environmental factors like temperature and humidity.
Environmental Factors: Temperature, light intensity,
humidity, and soil moisture can affect the rate of gas
exchange in tomato plants.
Stress Responses: Water deficits, soil flooding, and
even neighboring plants can impact gas exchange in
tomatoes, potentially leading to reduced
photosynthetic rates.
Hormonal Influence: Abscisic acid (ABA) and
jasmonic acid (JA) can influence stomatal responses
and gas exchange in tomato plants, particularly
under stress conditions.
Specialized Structures: Unlike animals, plants do not
have specialized gas exchange organs like lungs, but
stomata and lenticels serve a similar function.
KEY ASPECTS OF GAS EXCHANGE IN
TOMATOES:
FUN FACTS:
Tomatoes originated in South America and were
first cultivated by the Aztecs.

19. SUNFLOWER:
GAS EXCHANGE IN SUNFLOWERS, LIKE IN
MOST PLANTS, OCCURS PRIMARILY THROUGH
STOMATA, SMALL PORES ON THE LEAF
SURFACE, MAINLY ON THE UNDERSIDE. THESE
PORES FACILITATE THE MOVEMENT OF
CARBON DIOXIDE (CO2) INTO THE LEAF FOR
PHOTOSYNTHESIS AND THE RELEASE OF
OXYGEN (O2) AND WATER VAPOR (THROUGH
TRANSPIRATION).
FUN FACTS: They are known for their ability to
track the sun (heliotropism), although this
behavior stops once they mature. Each
sunflower head is actually made up of
thousands of tiny flowers, and they can grow to
impressive heights, with the tallest on record
reaching over 30 feet.ubheading
