Past medical history of rheumatic heart disease with mitral valve stenosis.

以前有风湿性心脏病伴二尖瓣狭窄病史。

Finally, Marfan syndrome is a risk factor for mitral valve prolapse, where the mitral valve pouches into the left atrium during systole.

，马方综合征也是二尖瓣脱垂的一个危险因素，即二尖瓣在收缩期时突向左心房。

That's where the mitral valve closing is best heard.

这个位置就是二尖瓣关闭的佳位置。

Inside the glomerulus, the olfactory axons meet up with the dendrites of another kind of nerve cell, called a mitral cell, which relays the signal to the brain.

在肾小球内，嗅觉轴突与另一种神经细胞的树突相遇，称为二尖瓣细胞，将信号递到大脑。

Might I ask you--would you have the kindness? I have grave doubts as to my mitral valve, if you would be so very good.

可以不可以请求您--您肯不肯给一？劳驾吧，心脏的僧帽瓣也许有毛病。

For example, the right and left atria are both full of blood, and that blood moves through the tricuspid and the mitral valve to get down into the ventricles.

例如，右心房及左心房充满了血；这些血将经从二尖瓣及三尖瓣到心室。

The aortic I may rely upon, but I should value your opinion upon the mitral.

的大动脉还好，可是对于的僧帽瓣，您的宝贵的意见。

As a result, every combination of an olfactory neuron and a mitral cell is like a single note, and the smell coming off of this pizza triggers countless of those combinations, forming a delicious musical chord of smells.

因此，嗅觉神经元和二尖瓣细胞的每一个组合都像一个音符，披萨散发出的气味会触发无数这样的组合，形成美味的气味音乐和弦。

Oh, the echo tests showed mild mitral stenosis. The tilt test was negative. We're doing E.P. Studies.

哦，超声波检查表明轻微的二尖瓣狭窄。穿刺结果也不好。们在做EP研究。

The mitral valve only has two cusps or leaflets one in front, called the anterior leaflet (that's a little smaller), and one behind it, called the posterior leaflet.

二尖瓣只有两个尖瓣叶：一个在前面，叫前叶，小一些；另一个在面，叫叶。

So, once a mitral cell picks up its signal from an olfactory neuron, it sends it along the olfactory tract to the olfactory cortex of the brain.

因此，一旦二尖瓣细胞接收到来自嗅觉神经元的信号，它就会沿着嗅道将其发送到大脑的嗅觉皮层。

The chambers on the left side are underdeveloped. In addition, the mitral valve, which connects these two chambers, is abnormally narrow.

左心室发育得不完全。而且二尖瓣连接着左右心室也狭窄得很严重。

And because it's basically the tricuspid and mitral valve closing, it's best heard in the tricuspid valve and mitral valve area.

因为它主是因为二尖瓣和三尖瓣关闭的声音，所以它可以在二尖瓣和三尖瓣诊区被清晰到。

So for each mitral cell, there are any number of olfactory axons synapsing with it, each representing and identifying a single volatile chemical.

所以对于每个二尖瓣细胞，有任意数量的嗅觉轴突与其突触，每个代表并识别一种挥发性化学物质。

After entering the left atrium, the blood goes through the second atrioventricular valve called the mitral valve into the left ventricle.

进入左心房，血液穿过第二个房室瓣膜，称为二尖瓣，进入左心室。

So the first " lub" that you hear in that lub-DUB is made by the mitral and tricuspid valves closing.

所以你在 lub-DUB 中到的第一个“lub”是由二尖瓣和三尖瓣关闭发出的。

Then the atrium contracts, which increases the pressure, so the blood passes down through the mitral valve into the left ventricle.

然心房收缩，增加压力，所以血液通过二尖瓣进入左心室。

That first heart sound, " lub" , is called S1, and the noise comes from the tricuspid and mitral valves snapping shut when the left and right ventricles contract, which happens at about the same time.

第一心音“lub”叫做S1，是在左、右心室同时收缩，三尖瓣和二尖瓣关闭时发出的声音。

Right after the S2 sound, the tricuspid and mitral valves open back up allowing blood to fill up the ventricles again and this period of time is called diastole.

在S2之，三尖瓣和二尖瓣打开；让血液再次充盈心室，这段时期叫做心脏舒张期。

After leading to a glomerulus, these neurons synapse with mitral cells, which go on to send signals to the brain.

在通过肾小球，这些神经元与二尖瓣细胞突触，二尖瓣细胞继续向大脑发送信号。
