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

以前有风湿性心脏病伴狭窄病史。

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

最后，马方综合征也是脱垂的一危险因素，即在收缩期时突向左心房。

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

这位置就是听关闭的最佳位置。

He lifted massively heavyweights, and it turned his aortic valve, the one that looks like a Mercedes sign, into a bicuspid double triangular flap.

他能举起巨大的重物，使用类固醇把他的主动脉，那看起来像梅赛德斯标志的膜，变成了只有一膜，两三膜。

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，嗅觉轴突另一种神经细胞的树突相遇，称为细胞，将信号传递到大脑。

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；这些血将经从及三到心室。

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，嗅觉神经元和细胞的每一组合都像一音符，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狭窄。穿刺结果也不好。我们在做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.

只有两叶：一在前面，叫前叶，小一些；另一在后面，叫后叶。

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.

因为它主要是因为和三关闭的声音，所以它可以在和三听诊区被清晰听到。

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

所以对于每细胞，有任意数量的嗅觉轴突其突触，每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.

进入左心房后，血液穿过第房室膜，称为，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 中听到的第一“lub”是由和三关闭发出的。

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

然后心房收缩，增加压力，所以血液通过进入左心室。

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，三和关闭时发出的声音。

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之后，三和打开；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.

在通过肾小球后，这些神经元细胞突触，细胞继续向大脑发送信号。

He has a murmur of mitral insufficiency.

他有关闭不全的杂音。
