The aorta and its major branches are elastic arteries — they contain more elastin than any other blood vessel type, so they can absorb the large pressure fluctuations as blood leaves the heart.

主动脉及其主要分支是弹性动脉——它们比任何其他血管类型都含有更多的弹性蛋白，因此它们可以吸收血液离开心脏时的巨大压力波动。

And then we've got the problems on the blood vessel end, under sustained hypertension, you may see your otherwise elastic arteries go from being flexible balloons to stiff, hardened pipes, in what's called arteriosclerosis.

然后血管末端出现了问题，在持续的高血压下，你可能会看到你原本弹性的动脉从灵活的气球变成僵硬、硬化的管道，这就是所谓的动脉硬化。
