Let's move our attention to another area.
下面我們來看其他的一些內容
Let's focus on this right here, which is the interventricular septum.
來看這里，室間隔
And you can think of a septum as basically a wall. Interventricular septum.
間隔就像兩個空間之間的一堵墻。室間隔
And this interventricular septum, the one thing I want to point out, which is maybe fairly obvious,
大家看心室間隔，我要強調一點，可能非常明顯
when you look at it, you might think, why did you even have to say it?
大家可能覺得不值得單獨指出
That's pretty obvious, this area is really thin and this area is really thick by comparison, right?
但大家看，這里比較薄，而這塊相對較厚，對吧？
The two areas are not equal in size, this is much thicker.
這兩個區域大小不對等，這里要厚一些
And the reason I wanted to bring that up is because this first area, in blue, is called the membranous part.
之所以單獨強調這一點，是因為大家看藍色的部分，這是膜性部分
Literally like a membrane. Membranous.
看起來就像一層膜
The bottom, the red part, is the muscular part.
下邊紅色的，是肌肉部分
This is the strong muscular part.
肌肉部分比較有力量
So you have two different areas in that interventricular septum,
在兩個心室的室間隔中
the wall between the ventricles.
有兩種不同的部分
And one of the interesting things about the membranous part in particular,
而關于膜性部分有一個問題
is that a lot of babies are born with holes in that membranous part.
很多新生兒這部分容易有孔洞
So- when I say a lot I don't mean the majority of babies by any means.
我說的很多，并不是說大多數新生兒都會有
But one of the most common defects, if there is going to be a defect,
只是說在新生兒缺陷中
would be that you would actually have a communication between these two.
這種缺陷比較普遍
So that the blood could actually again flow from a place that it's not supposed to go, the left ventricle,
那么血液可能從左心室流到右心室
into a place it shouldn't be going, the right ventricle.
造成這樣的流動路線
So blood can actually flow through those holes and that is a problem.
因此孔洞成為一個很大的問題
So that is called a VSD.
這種疾病叫做VSD
And actually you might hear that term at some point,
可能大家有聽說過這個名詞的
so I just want to point out where that happens.
我給大家介紹一下這種情況是怎么發生的
VSD. And while I'm writing VSD,
這種疾病叫做VSD
you can take a stab at guessing what it might stand for.
大家可以猜一下這個縮寫是什么意思
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.
相對于肌肉部分，VSD更普遍出現在膜性部分的病變中
