that are used to treat disease in these blood vessels

它就是用于治疗这些血管中的疾病
and we'll talk more of that as we go through the next couple of weeks.

在接下来几周我会说到更多相关内容
What I want you to focus on now

现在我要你们注意的是
is just this phenomenon that the flow branches here.

血液在流经这个分支时发生的现象
Some of the blood goes further down the aorta

一部分血液沿着大动脉流走了
and some of it goes through the coronary arteries.

另一部分则流经冠状动脉
Now, how much blood goes in which direction

那么各个支路上到底有多少血液流过
is going to be one of the main things we talk about

是这节课接下来的时间里
in the rest of the lecture today,

我要讲的主要内容
but first let's just continue in our journey around.

但首先让我们继续追踪血液的旅程
You'll notice that this pattern repeats

注意在每一个分支点
that there are points where the flow branches.

这个过程都被重复着
