Tie trachssl wind-pipe) alter passing
into the cavity of the chest, is divided into
two principal par.s. one Of which passes
to tbs right. the other TO ths Ieft lung;
these are called the bronchial tubes: and
disease Of them or their Fami6catious, Is
called Bronehiiis. After passing into the
lungs, these tubes are subdivided, until
they terminate in what is called air cells
In truth It may be said, that the substance
the lungs is but tho development, or rex;
pansion Of the bronchial tubes; their en-
tire structure almost. consistiBgof excee-
dinghy thin, delicate membrane. Over
the internal surface Of the traches, and all

The manner Of depdTation of the blood
) in the ldbgs, Is as follows. The blood.
when il comes from the heart, and is
spread through the lungs, las will be fnl'
" explained hereafter, when describing
1.-The circulation, q is OF a dark color, from
con tainiug carbonic acid gas anil other
excremsnlious matter, taken up from the
blood 10 the general round ofths circulation.
? This dark or fenous blood, is spread ont
through the lungs Immediately behind the
delicate membranes, forming tbeair cells.
AT every inspiration the lungs are filled
with atmospheric air which, takes from
the blood its excremehtious matter, aud
: imparts to il pure oxygen, which chan,
!. ges itfrom dark, to a bright red color -
, Il is then called srterial blood; and returns
to the heart, through the Pdlmohary
vein.
a This change from vsnous, 10 srterial
s blood, at every inspiration, is essential to
h life: as pure srtsrial, or oxYgenatsd blood,
!, is the arp: opriate stimulus of the brain,
