Remember how fluid buildup increased pressure in the pulmonary artery?

体液积聚如何增加肺动脉压力吧？

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

不过，来自肺动脉的血液不含氧。

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

在肺动脉上。导线的作用就像脏上的永久性划片。

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

血从左流入主动脉，以及从右流入肺动脉。

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

注意，这条大动脉确实会分成主动脉和肺动脉。

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脉弓，下面是肺动脉。

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

大动脉指的就是这两条把血液带离脏的主要动脉：主动脉和肺动脉。

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

接着，血液从右房进入右被泵入肺动脉，最终进入肺。

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

肺动脉将脱氧血从脏输送到肺。

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，可见主动脉来自于左，肺动脉来自于右。

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血液，患者右和肺动脉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.

肺动脉携带来自于右的低氧血液，而肺静脉将来自于肺的富氧血液运至左房。

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指大血" Great vessels" ，包括了上腔静脉、下腔静脉、升主动脉、主动脉弓、肺动脉与降主动脉。

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脉或从脏通往肺部、携带缺氧血的肺动脉中。

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

如果主动脉和肺动脉这两条大动脉不分开的话，你就会有这条从发出的大动脉。

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.

一旦血液通过肺动脉瓣，便会进入肺动脉；肺动脉将血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.

血液从肺动脉进入较细小的肺小动脉，最后进入毛细血。

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

收缩时，血液在通过右肺动脉和左肺动脉向每个肺分支前被推入短肺干。

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-大动脉转位，即L-TGA，左旋的意思是主动脉主要位于肺动脉的左侧。

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.

右通过肺半月瓣将血液泵入肺动脉干，肺动脉干只是一个大血，它分裂形成左右肺动脉。
