The arrangement of tissue in the internal elastic lamina of muscular pulmonary arteries in rats has been studied. It consists of long plates of elastic tissue joined to each other by side branches, thus forming a continuous branching network. The thick plates are orientated parallel to the long axis of the vessel. This is similar to the arrangement in the saphenous and splenic veins in the dog. Systemic arteries show a different arrangement, usually a single fenestrated sheet. The differences between systemic and pulmonary arteries can be explained by considering the different biomechanical forces acting on them.
对大鼠肌性肺动脉内弹性膜中的组织排列进行了研究。它由弹性组织的长板组成，这些长板通过侧支相互连接，从而形成一个连续的分支网络。厚板与血管的长轴平行排列。这与狗的隐静脉和脾静脉中的排列相似。体循环动脉呈现出不同的排列，通常是单个有孔的薄片。体循环动脉和肺动脉之间的差异可以通过考虑作用于它们的不同生物力学力来解释。
