THE HUMAN RESPIRATORY SYSTEM
PASSAGE OF AIR – THE BEGINNING


Air enters the respiratory system through the
and
. It then passes
through the throat (which is made up of the
and
).
A structure called the
covers the top of the trachea during swallowing to prevent
and
and ____________________________________________
THE TRACHEA


The trachea (also known as the
) is supported by rings of
the trachea open. Cells covering the trachea and bronchi are covered with
.
The mucus and cilia trap
. The cilia
which keep
and layers of
LARYNX


The
(also known as the voice box) is located at the top of the
As air passes through the larynx, the
vibrate which produce

PASSAGE OF AIR CONTINUED – BRONCHI AND BRONCHIOLES

The trachea divides into two branches called
. The bronchi divides into another
. These are tubes that carry air into the
of tubes called the
GAS EXCHANGE: ALVEOLI



At the end of bronchioles are tiny grape-like
called
.
Alveoli are structures with
that are surrounded by
(tiny blood vessels)
Alveoli are the site of
.
GAS EXCHANGE: MOVEMENT OF GASES
The concentration of oxygen in blood flowing through the lungs < oxygen in the air in alveoli
 This ensures that oxygen always
and is carried to the tissues.
 Oxygen then diffuses from _____________________ into the ______________________
 At the same time, the
from body tissues are picked up by the blood and
______________________ where it diffuses out into the air in the alveoli and is
.
BREATHING

Inhalation:

Exhalation:

Breathing uses muscles that move the
and the
______.
Diaphragm: large sheet of _
__ underneath
the lungs that
and
_____
When we inhale, our chest
_
_ and our
diaphragm
_
__ (lowers / flattens).
When we exhale, our chest
__ and
our diaphragm
__(rises / dome shaped).


CONTOL OF BREATHING




Breathing is mostly
(automatic). It can be temporarily overridden (for
example when we talk or hold our breath) but eventually the automatic system takes over.
Breathing is controlled by a part of the brain that detects
.
As the
, the brain sends signals to the
,
, and heart.
This will increase the
and cause the heart to
