The arterial system formed by branches of the vertebral and basilar arteries in guinea pig was compared to that of dog and human. The vertebrobasilar arterial system in particular species shows similarities and differences, considering its structure and arising branches. The differences are mainly due to the length of the basilar artery. In guinea pig the vertebrobasilar system distribute blood to the 2/3 of the brain. The same distribution is in dog. In human the carotid system predominates in the supply of the brain.
将豚鼠中由椎动脉和基底动脉分支形成的动脉系统与狗和人类的动脉系统进行了比较。考虑到其结构和分支情况，特定物种的椎基底动脉系统呈现出异同。差异主要源于基底动脉的长度。在豚鼠中，椎基底系统将血液输送到大脑的三分之二区域。狗的情况也是如此。在人类中，颈动脉系统在大脑供血中占主导地位。
