The respiratory system works with the circulatory system to

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

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

which keep


The

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

MOVEMENT OF GASES – GAS EXCHANGE





The oxygen we breathe in through our
and
and eventually enters our lungs.
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

tissues are picked up by the blood and
where it diffuses out into the air in the alveoli and is

Breathing is mostly

Breathing is controlled by a part of the brain that detects
