Distribution of
the Pulmonary vessels
To proceed in the next place with the
consideration of the distribution of the Pulmonary vessels.
It will be found that nothing can be easier than to
trace out the course and Ramifications of the
Pulmonary arterys and veins when a pair of
lungs, injected in the manner above described,
with the arteries of one colour and the veins of
another is examined - The mode of distribution
of each is marked, decisive and invariable.
The Pulmo=
=nary artery
The Pulmonary artery is seen always accom=
=panying the Bronchial tube, dividing as it
divides and maintaining an exact correspon=
=dence with its subdivisions, down to the point
at which the terminal Bronchial tubes give off their
pedicels - In some works it is asserted that
as they diminish in size the <s>Bronchial<\s> pulmonary arteries
become more numerous than the Bronchial tubes;
this is not the case: whenever there is a Bronchial
tube there is also one corresponding Pulmonary
artery and never more than one - Throughout
the lung the Pulmonary artery always runs on
the upper surface of the Bronchial tube, and
