A closer look
The tube leading to the lungs is called the trachea …
Which divides into two smaller tubes called bronchi
Which
divide into smaller
tubes called bronchioles
until you get to the
alveoli (air sacs)Slide6

How do we breathe?
diaphragm
http://www.biotopics.co.uk/humans
The diaphragm is a very powerful muscle.
Watch how it controls breathing
When the diaphragm moves down …
the lungs expand and air is drawn in.
When the diaphragm moves up …
the lungs are squeezed and air is forced out
And it all happens without you trying!Slide9
ActivitySketch, complete and annotate a diagram to describe:Breathing in
Breathing outYou must explain clearly all the actions and processes involved in breathing.Slide10
Peer assessment criteria
Breathing in
:
The diaphragm contracts (moves down)The intercostal
muscles contract moving the rib cage up and out.The volume increases The pressure decreases.Air is sucked in
Ribs move up and out
Diaphragm moves downSlide11
Peer assessment criteria
Breathing out
:
The diaphragm relaxes (moves up) The intercostal muscles relax moving the rib cage down and in.The volume decreases The pressure increases.
Air is forced out
Ribs move in and down
Diaphragm moves upSlide12
