Let's move our attention to another area.
下面我们来看其他的一些内容
Let's focus on this right here, which is the interventricular septum.
来看这里，室间隔
And you can think of a septum as basically a wall. Interventricular septum.
间隔就像两个空间之间的一堵墙。室间隔
And this interventricular septum, the one thing I want to point out, which is maybe fairly obvious,
大家看心室间隔，我要强调一点，可能非常明显
when you look at it, you might think, why did you even have to say it?
大家可能觉得不值得单独指出
That's pretty obvious, this area is really thin and this area is really thick by comparison, right?
但大家看，这里比较薄，而这块相对较厚，对吧？
The two areas are not equal in size, this is much thicker.
这两个区域大小不对等，这里要厚一些
And the reason I wanted to bring that up is because this first area, in blue, is called the membranous part.
之所以单独强调这一点，是因为大家看蓝色的部分，这是膜性部分
Literally like a membrane. Membranous.
看起来就像一层膜
The bottom, the red part, is the muscular part.
下边红色的，是肌肉部分
This is the strong muscular part.
肌肉部分比较有力量
So you have two different areas in that interventricular septum,
在两个心室的室间隔中
the wall between the ventricles.
有两种不同的部分
And one of the interesting things about the membranous part in particular,
而关于膜性部分有一个问题
is that a lot of babies are born with holes in that membranous part.
很多新生儿这部分容易有孔洞
So- when I say a lot I don't mean the majority of babies by any means.
我说的很多，并不是说大多数新生儿都会有
But one of the most common defects, if there is going to be a defect,
只是说在新生儿缺陷中
would be that you would actually have a communication between these two.
这种缺陷比较普遍
So that the blood could actually again flow from a place that it's not supposed to go, the left ventricle,
那么血液可能从左心室流到右心室
into a place it shouldn't be going, the right ventricle.
造成这样的流动路线
So blood can actually flow through those holes and that is a problem.
因此孔洞成为一个很大的问题
So that is called a VSD.
这种疾病叫做VSD
And actually you might hear that term at some point,
可能大家有听说过这个名词的
so I just want to point out where that happens.
我给大家介绍一下这种情况是怎么发生的
VSD. And while I'm writing VSD,
这种疾病叫做VSD
you can take a stab at guessing what it might stand for.
大家可以猜一下这个缩写是什么意思
Ventricular- and S is septal. Again septal just means wall. And D is Defect.
V是Ventricular(心室) S是Septal(隔膜) D是Defect(缺陷)
So a VSD is most common in that membranous part, more so than the muscular part.
相对于肌肉部分，VSD更普遍出现在膜性部分的病变中
