a biological system consisting of specific organs and structures used for the process of respiration in an organism, intake and exchange of oxygen and carbon dioxide between an organism and the environment, explore anatomy of the upper and lower respiratory tracts, from nasal passages to the lungs

1. Human Anatomy & Physiology
Respiratory System

3. Respiratory System
The respiratory system brings air into the body
and removes carbon dioxide. It includes the
nose, trachea, and lungs.

5. The respiratory system consists of the
Trachea
Bronchi
Lungs
which provide the passageway for air, in and out of
the body. Oxygen is needed by every cell of the body
for survival
Nose
Naso pharynx
Pharynx
Larynx
Upper
Lower

6. Functions of the Respiratory System
Guess....? For what we are Breath....

7. We know that each & every cell of our body
require
Oxygen
Water
To produce ENERGY
Nutrients

8. Exchange of gases – oxygen and carbon dioxide exchange is the
primary function of the respiratory system in order to sustain life.
Gas exchange
that's the
name of the
game

9. Olfaction – specialised nerve endings embedded in
the nasal cavity send impulses for the sense of smell
to the brain.

10. Speech
The vocal cords in the larynx aid in producing speech.
Functions of the Respiratory System

11. larynx is a cartilaginous
structure at the top of the
trachea which contains
elastic vocal cords that are
the source of the vocal tone
when we speak
The larynx is bigger in
males than it is in females,
which attributes to the
deeper voice in males.

12. Homeostasis – the respiratory system helps to maintain
homeostasis by maintaining oxygen levels in the blood and
through the elimination of wastes such as carbon dioxide and
heat, also maintain the pH of Blood.

13. Respiratory Anatomy
Sinuses
Hollow spaces in the bones of the head that are connected to
the nose by small openings, responsible for monitoring the
temperature and humidity of the air breathed in, as well as
adding resonance to the voice.
Nose (nasal cavity)
Optimal entrance for inhalation due to hairs lining the walls
and filtering the air.

14. Cilia
Very small hairs that have a wave-like motion that is responsible
for carrying mucus into the throat where it is coughed up or
swallowed
Hairs in the nose help to clean the air we breathe as well
as warming it.

15. Sticky phlegm, liquid.
Mucus traps dust, germs and unwanted matte that
has invaded the lungs. It is disposed of by coughing,
sneezing, clearing your throat and swallowing.
The common cold is the most common respiratory infection
* The common cold is caused by 200 different viruses
Mucus

16. Tonsils
Responsible for fighting germs, but these lymph
nodes in the wall of the throat often become
infected and in many cases are removed.

17. Pleura
A continuous membrane folded over itself, the pleura is
often considered two. This surrounds each lobe of the
lungs, separating the lungs from the chest wall.
pleuritis

18. Diaphragm
Part of the muscular system and a major part of respiration;
this strong wall of muscle is situated between the chest
cavity and the abdominal cavity. Moving downward creates
suction in the chest and draws are in while expanding the
lungs. Exhalation is the opposite process.

19. Ribs
Slightly moving part of the skeletal system that is
responsible for the protection of the chest cavity.

20. Throat (pharynx)
Acts as a passageway allowing air coming in from
the nose and mouth into the trachea (windpipe).
Throat

21. Epiglottis
This simple flap of tissue protects the entrance of the
trachea, opening during respiratory functions and
closed while swallowing to re-direct substances other
than air to the esophagus and stomach.

Epiglottis

22. Esophagus
Passageway from the
mouth and throat to the
stomach.
.The breathing rate in women and children is faster than men
Windpipe (trachea)
Passageway from the pharynx to the lungs.
The trachea (TRAY-kee-uh} is sometimes called
the windpipe. The trachea filters the air we breathe
and branches into the bronchi.

23. The surface area of the lungs is roughly the
same size as a tennis court.
The capillaries in the lungs would extend 1,600
kilometres if placed end to end.
We lose half a litre of water a day through
breathing. This is the water vapour
we see when we breathe
onto glass.

24. When you are sleepy or drowsy
the lungs do not take enough
oxygen from the air. This causes
a shortage of oxygen in our
bodies. The brain senses this
shortage of oxygen and sends a
message that causes you to take
a deep long breath---a YAWN.

25. Bronchial Tubes
The trachea divides into
two main tubes, known
as the Bronchial Tubes,
The bronchi (BRAHN-ky) are two air tubes
that branch off of the trachea and carry air
directly into the lungs.

26. Right Lung
The right lung is made of
three lobes, sections. Each
lobe is filled with alveoli, air
sacks, and the air moves in
and out through one
bronchial tube.
.The right lung is slightly larger than the left
Left Lung
The left lung is made of
two lobes, sections. Each
lobe is identical to those of
the Right Lung.

27. Bronchioles
The smallest subdivisions
of the bronchial tubes and
the location of the air sacs
(singular alveoli, plural
alveolus)
Alveoli
These air sacs are the final destination of the air
taken in during inhalation before entering the
circulatory system.

28. Pulmonary Artery
Blood that is oxygen-poor is carried to the capillaries
around the alveoli.
The name for a specialist of the respiratory system is called pulmonologist.

29. Pulmonary Vein
Oxygen-rich blood returns to the heart and blood
stream via the pulmonary vein.
People under 30 years of age take in double the amount of
oxygen in comparison to a 80 year old.
Pulmonary
Vein
Oxygen-
rich blood

30. Capillaries
Blood vessels and members of the circulatory system,
they are imbedded in the walls of the alveoli where
oxygen diffuses into
the blood they
contain and carbon
dioxide replaces it in
the alveoli to be
exhaled.
