Respiration?
An important system in which oxygen and
carbon dioxide are exchanged between
cells, blood, and air in the lungs.
Main Job?

It is a simple task, to
exchange oxygen and
carbon dioxide.
 However, without
oxygen, cells lose much
of their ability to
produce ATP
 ATP is needed to
synthesize new
molecules, pump ions,
and carry nerve
impulses.
-Your body keeps
up with your needs,
like running, the
muscle cells need
more oxygen to do
what you want.
More in depth…
Inhaled, they fill up with oxygen
and other gases, then as a gas
waste, carbon dioxide is
exhaled.
This allows the volume of
the chest cavity to
expand, therefore allowing
us to breath, thus air
rushing into the passages.
The windpipe that
serves as a air
passage to the
lungs.
Into the Lungs
A passage way for the air to get
into the alveoli and undergo gas
exchange.
Millions of tiny air sacs
clustered like grapes are
wrapped around a delicate
layer of thin capillaries in
which gas exchange
begins.
Gas Exchange-Step 1
Inhaling, oxygen is
diffused into the
capillaries when
carbon dioxide is
diffused oppositely
when exhaling.
Gas Exchange-Step 2
Deoxygenated blood
is passed through
the capillaries and
when the oxygen
inhaled arrives at the
alveoli, the oxygen is
then grabbed by the
blood. Oxygen and
carbon dioxide pass
through two layers,
the epithelium, and
the wall of capillary.

Protective Procedures
1. To keep the lungs
clean important cells
called the cilia is found in
the lining of the trachea
and trap unwanted
particles of dust or
smoke.

2. In the nose there are tiny hairs
trap bacteria from getting in.
The lymphatic system
produces mucus where it is
formed to trap bacteria when
breathing. Major role in
immune system as well.

Protective Procedures
3. Mucus keeps the passageways
and pharynx (throat) warm and
moistened so that air can be
filtered perfectly.

4. As a waste basket, cilia
sweep the mucus and dirt
to the pharynx or throat to
be swallowed or spit out.

There is one small difference, birds need more air sacs
for flight. When taking off, birds require more strength to
hover, when in the air they require less from lifting winds,
but with the high altitudes it is hard to breath, therefore
more air sacs.
