The aorta is one continuous tube divided into the following regions

①升主动脉，靠近心脏且位于心包内。

Your aorta is one long, continuous tube with many branches that come off of the vessel like back roads would come off of a highway.

主动脉是一根长长的，连续的管，有许多分支，从血管上脱落，就像从公路上分支的小路。

Now, I'm quite sure that you're familiar with the key players here — they're the hollow organs that form the continuous tube that is your alimentary canal, aka the gastrointestinal tract, which runs from your mouth to your anus.

现在，我很确定你对这里的关键选手很熟悉——它们是形成连续管子的中空器官，也就是你的消化道，也就是胃肠道，从你的嘴延伸到你的肛门。
