This time, though, that blood comes from the pulmonary arteries, carrying deoxygenated blood.

不过，来自肺动的液不含氧。

And that's up in the pulmonary artery. The wire lead acts like permanent paddles on a heart.

在肺动上。导线的作用就像脏上的划片。

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

从左室流入主动，以及从右室流入肺动。

Notice though, that this one big artery does split into the aorta and pulmonary artery.

注意，这条大动确实会分成主动和肺动。

Remember how fluid buildup increased pressure in the pulmonary artery?

还记得体液积聚如何增加肺动压力吧？

The " great arteries" , are these two main arteries taking blood away from the heart —the aorta and pulmonary artery.

大动指的就是这两条把液带离脏的主要动：主动和肺动。

The pulmonary arteries carry deoxygenated blood from the heart to the lungs.

肺动将脱氧从脏输送到肺。

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

一旦脏完全发育，可见主动来自于左室，肺动来自于右室。

Since there's more oxygenated blood over here, patients will have an increased oxygen saturation in the right ventricle and pulmonary artery.

既然来了更多含氧高的液，患者右室和肺动的氧饱和度就升高了。

Pulmonary vessels include the pulmonary artery and its branches, and the veins that drain the lung capillaries.

肺动携带来自于右室的低氧液，而肺静将来自于肺的富氧液运至左房。

This usually occurs in the deep veins of the legs or in the pulmonary arteries that carry deoxygenated blood from the heart to the lungs.

这经常发生在腿部的深静或从脏通往肺部、携带缺氧的肺动中。

On the left side of the heart, the aortic arch should be the highest up followed by the pulmonary artery.

脏左侧的最高点应为主动弓，下面是肺动。

From there the blood goes into the right ventricle and gets pumped into pulmonary artery and eventually into the lungs.

接着，液从右房进入右室并被泵入肺动，最终进入肺。

If these two great arteries, the aorta and pulmonary artery, don't divide, you essentially have this massive artery coming from both ventricles.

如果主动和肺动这两条大动不分开的话，你就会有这条从室发出的大动。

Once it's passed the pulmonary valve, the blood goes into the pulmonary arteries, which carry blood away from the heart to the left and right lung.

一旦液通过肺动瓣，便会进入肺动；肺动将液从脏输送到左肺和右肺。

So that blood goes from the pulmonary artery into a pulmonary arteriole, which is a little bit smaller and, finally, into a capillary which is the smallest.

液从肺动进入较细小的肺小动，最后进入毛细。

When the ventricle contracts, blood is pushed into the short pulmonary trunk before branching toward each lung through the right and left pulmonary arteries.

室收缩时，液在通过右肺动和左肺动向每个肺分支前被推入短肺干。

Lastly, G is for great vessels which includes the superior vena cava, inferior vena cava, ascending aorta, aortic arch, pulmonary artery, and descending aorta.

最后，G指大" Great vessels" ，包括了上腔静、下腔静、升主动、主动弓、肺动与降主动。

Less commonly, babies can have levo-transposition of the great arteries, or l-TGA, with levo meaning that the aorta's primarily to the " left" of the pulmonary artery.

更少见地，宝宝可能会有左旋-大动转位，即L-TGA，左旋的意思是主动主要位于肺动的左侧。

The right ventricle pumps blood through the pulmonary semilunar valve into the pulmonary trunk, which is just a big vessel that splits to form the left and right pulmonary arteries.

右室通过肺半月瓣将液泵入肺动干，肺动干只是一个大，它分裂形成左右肺动。
