Question: How does air move through stuff?

Hey Jessie,

So air doesnt move through everything, it can only move through things that have spaces or gaps in their structure to allow it (you can breathe through a jumper but cant breathe through concrete) and if it can it will move from an area of hugh oxygej concentration to an area of low oxygen concentration (similar to if you sprayed deodorant in one side of the room it would eventually be smelt on the other.)
.
However if we are talking biologically (like air moving through our lungs?) If so i can shed some light on that in the comments down below ☺.
