Ollie found himself travelling down a tunnel. It seemed to have
ridges in it to keep it open. He thought this must be a windpipe
Ollie the Oxygen molecule was floating around one day when
WHOOSH! He was sucked into a dark hole – he was in a mouth!
Inside the lung, the tubes started to get narrower and
narrower until he was in a tiny little air sac. The walls of the
sac were very thin and he easily squeezed through. But then…
Ollie reached a fork in the tunnel. Which way would he go
down? Before he could think, he was whizzing down the left
bronchus into the left lung
Wheeeeee! He was in the blood and being carried along by the
powerful force of the blood
