The document describes the main parts of the respiratory system and how breathing works. It lists the nostrils, pharynx, larynx, trachea, lungs, diaphragm, bronchi, and bronchioles as key parts. It explains that during inhalation, air enters through the nose or mouth and passes through the larynx, trachea, bronchi, and into the lungs, where oxygen is absorbed. During exhalation, the process occurs in reverse as carbon dioxide is expelled through the same pathways.

DIFERENT
PARTS

3. PROCESS
First to inhale we get
oxygen by the mouth and
the nose , then it goes
into the larynx and into
the trachea . Later it
goes to the primary
bronchus and next to the
lungs. Finally to exhale,
the carbon dioxide goes
the same process all the
way up.

4. NOSTRILS
Nostrils are the 2
nose holes that
we use to inhale
or exhale.

5. LARYNX
The larynx is a
structure at the top
of the trachea that
contains the vocal
cords that are the
source of the vocal
tone.

6. PHARYNX
The pharynx is a part of
the body that helps with
eating and with breathing.
It starts on the mouth
and nose and it ends on
the esophagus and the
larynx.

7. TRACHEA
The trachea is a
tube from the
larynx to the
bronchi that
carries the air to
the lungs.

8. LUNGS
Your lungs are part of the
respiratory system, a
group of organs and
tissues that work together
to help you breathe. The
respiratory system's main
job is to move oxygen into
your body and expel
carbon dioxide.
