come into contact with the larger Bronchial tubes,
and one of them becomes placed on the under sur=
=face of each tube, but still continues to run in
an interlobular space - They collect similar branches
from other lobules and receive the trunks of the
ramusculi, which run on the outer surface of
each Bronchial tube and collect the blood from the
plexus within it, and thus they continue to increase
in size until they terminate in the four large veins
which enter the left auricle of the heart -
In this course, no branches of any sort or kind are
given off from them to any tissue whatever, and they
receive no contributions from the Brochial vessels;
most certainly the blood brought by the Bronchial
arteries is not conveyed back to the heart in the
smallest degree by these veins; otherwise there
would be a small circulation going on round
and round through the left side of the heart and
through a small portion of the lungs, and thus by
accident the blood destined for the supply of the body
at large might miss its way occasionally and
go back again to the lungs through the Bronchial
arteries and again find its way into the pulmonary
