JN Maina, P van Gils - Comparative Biochemistry and Physiology Part A …, 2001 - Elsevier
The bronchial system (BS), the pulmonary artery (PA) and the pulmonary vein (PV) of the
lung of the domestic pig, Sus scrofa were simultaneously cast with silicone rubber and
studied. Asymmetrical dichotomous bifurcation preponderated in the tree-like arrangement
of the three conducting systems. Lengths and diameters of the various generations were
measured. At the extremities of the BS and the PA, alveoli and blood capillaries related very
closely. In the cranial and middle lobes of the right and left lungs, topographically, the PA …
