His left ventricle's shot. It is barely pushing blood out.

他左侧心室中枪。几乎无法把血液压出去。

Blood flows from the left ventricle into the aorta and from the right ventricle into the pulmonary arteries.

血从左心室流入主动脉，以及从右心室流入肺动脉。

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，所以血液通过二尖瓣进入左心室。

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，血液穿过第二个房室瓣膜，称为二尖瓣，进入左心室。

Once it's fully developed, the aorta comes from the left ventricle and the pulmonary artery comes from the right ventricle.

一旦心脏完全发育，可见主动脉来自于左心室，肺动脉来自于右心室。

And that fantastic journey — known as the systemic loop — begins in the left ventricle, when it flexes to increase pressure.

这个奇妙的旅程——被称为全身循环——从左心室开始，它会弯曲以增加压力。

Both of these have chordae tendineae coming off of them that tether the valve to the papillary muscles in the left ventricle.

这两种都有腱索，连接到左心室的乳头肌上。

Because of this the kidneys get about a quarter of the cardiac output which is blood getting pumped out of the left ventricle.

因此，肾血流量约占心输出量（左心室输出量）的1/4。

The aorta dilates over time, which is a risk for aortic valve insufficiency, where blood leaks back into the left ventricle during diastole.

主动脉逐渐扩张，这是主动脉瓣关闭不全的危险因素之一；这种情况下，舒张期时血将反流至左心室。

Doppler's showing air in the left ventricle.

多普勒波显示左心室有空气。

Age 5. Multiple stab wounds. 5 Laceration to the left ventricle.

岁 多处刺伤左心室破裂致死。

I can almost hear my left ventricle slamming shut as I speak.

你还想加点芝士吗。

This is the valve that separates the left atrium and the left ventricle.

这是分隔左心房和左心室的瓣膜。

Depolarization then spreads to the larger left ventricle, resulting in a large downward deflection.

然后，去极化扩散到较大的左心室，导致一个大的向下偏转。

You're saying that his left ventricle had been weakened by the lvad malfunction?

你声称他的左心室因 起搏器故障而开始衰弱?

It pushes against the interventricular septum, causing it to bow out into the left ventricle.

血压推向室间隔，使之偏向左心室。

Let's review: your aorta exits your heart from the left ventricle.

主动脉从左心室流出。

But this negative activity is rapidly overwhelmed by current spreading through the left ventricle.

但是这种负性活动很快被通过左心室的电流所淹没。

On the left side, blood's now pumped from the left ventricle out to the pulmonary artery to the lungs, and then comes back to the left atrium and left ventricle and restarts.

对于左边来说，血液现在从左心室泵到了肺动脉进入肺，最后回到左心房，再进入左心室，然后重复这一循环。

Then fresh oxygenated blood comes from the lungs to the left atrium, goes to the left ventricle and is pumped through the aorta to the body.

然后新鲜的有氧血从肺部到左心房，再到左心室，后随主动脉泵入全身。
