蟒蛇在蛇中是独一无二的，因为心室内压力分离，所以在腹主动脉和肺动脉中具有不同的压力。在这项研究中，我们调查这是否与不同的血管强度在球蟒蟒蛇regius。我们切除了左、右、背侧肺动脉和两条肺动脉。对这些进行拉伸试验。我们发现，主动脉血管壁是显着强于肺动脉壁的王爵。大体形态学特征（血管壁厚度和相关的胶原含量绝对值）可能是最具影响力的因素。胶原纤维的厚度和方向可能会产生影响，但胶原纤维类型和纤维之间的交联的影响需要进一步研究。J. Morphol. 276：1412-1421，2015.© 2015 Wiley Periodicals，Inc.
Pythons are unique amongst snakes in having different pressures in the aortas and pulmonary arteries because of intraventricular pressure separation. In this study, we investigate whether this correlates with different blood vessel strength in the ball python Python regius. We excised segments from the left, right, and dorsal aortas, and from the two pulmonary arteries. These were subjected to tensile testing. We show that the aortic vessel wall is significantly stronger than the pulmonary artery wall in P. regius. Gross morphological characteristics (vessel wall thickness and correlated absolute amount of collagen content) are likely the most influential factors. Collagen fiber thickness and orientation are likely to have an effect, though the effect of collagen fiber type and cross‐links between fibers will need further study. J.
