The origin of the vertebral artery, the thyrocervical trunk and the internal mammaryartery is very constant.
椎动脉，颈干和乳内动脉的起源非常恒定。

This is an ideal animal model to study the competitive flow between the left anterior descending artery and the internal mammaryartery after coronary artery bypass grafting.
此动物模型可重复性高，操作简单，是较为理想的研究冠状动脉竞争血流的动物模型。
