TfL`s Red Blood Cells

TfL’s Red Blood Cells
Red blood cells are the
most common type of blood cell.
Buses can be found at three to five minute
intervals on the roads of London.
A red blood cell’s purpose
is to deliver oxygen to
the tissues of the body.
Passengers often board the
bus near their homes and alight
at their various destinations
(work, school, etc).
Every single cell is bright red
and shaped to accommodate
as much oxygen as possible.
Threadbare seats and a double deck
supposedly ensure that every single
passenger has adequate room
to sit beside (or lean against)
a fellow passenger.
Each cell has a very thin cell
membrane to allow oxygen to
diffuse through quickly.
Passengers enter and leave
through the double doors at the front
and halfway down each bus.
Red blood cells are vital: their main
function is to transport oxygen,
which is needed by all living cells
so that they may respire.
A subtle shade of chaos descends
on the city when a bus strike takes place.
Passengers travelling for work or school
stare at the clotted blockages
in the roads and swear that their hearts are
collapsing in their buttoned-up chests.
