That freshly oxygenated blood then heads off to the pulmonary veins, the heart, and then to the body's tissues!

富含氧的血液被运往肺静脉、心脏，最后到全身组织。

An urgent surgery showed a severe wound to the left pulmonary vein.

紧急手术显示左肺静脉严重受伤。

The oxygen-rich blood moves into a venule and then, eventually, into a pulmonary vein that dumps the blood into the left atrium.

富含氧气的血液汇入小静脉，最终进入肺静脉；肺静脉将血液排入左心房。

The capillaries carry this oxygen-rich blood to the pulmonary veins.

毛细血管将这种富含氧气的血液输送到肺静脉。

Pulmonary blood vessels shrink pumping more blood through the pulmonary veins into the left atrium.

肺血管收缩，将更多的血液通过肺静脉泵入左心房。

There are four pulmonary veins, two coming from each of your lungs.

有四条肺静脉，两条分别来自两个肺。

These pulmonary veins deliver the oxygenated blood to the left atrium.

这些肺静脉将含氧血液输送到左心房。

Once again, blood starts to back up in the left atrium, pulmonary veins, and pulmonary capillaries, ultimately leading to pulmonary hypertension and pulmonary edema.

血液又一次在左心房、肺静脉、肺毛细血管淤积，最终导致肺高压和肺水肿。

To get there, it travels through pulmonary veins, which are the large veins that carry oxygenated blood from the lungs to the heart.

要到达那里，它要经过肺静脉，肺静脉是将含氧血液从肺输送到心脏的大静脉。

In atrial fibrillation, electrical impulses are initiated randomly from many other sites called ectopic sites in and around the atria, commonly near the roots of pulmonary veins.

房颤时，心房内和心房周围的许多异位起搏点（通常是肺静脉根部附近）随机产生电脉冲。

The pulmonary arteries carry blood low in oxygen from the right ventricle, while the pulmonary veins carry blood high in oxygen from the lungs into the left atrium.

肺循环负责从血中排除二氧化碳并补充氧气。

The pulmonary veins carry the richest oxygenated blood because they just came from the lungs, and the pulmonary arteries carry oxygen-poor blood because they're heading to the lungs.

肺静脉携带富氧血液，因为它们只是来自肺部，而肺动脉携带贫氧血液，因为它们流向肺。

Atrial fibrillation is caused by multiple electrical impulses that are initiated randomly from many ectopic sites in and around the atria, commonly near the roots of pulmonary veins.

房颤是由多个电脉冲引起的，这些电脉冲是从心房内和周围的许多异位部位随机发起的，通常在肺静脉根部附近。

This idea holds true here because we see that the pulmonary arteries are carrying blood away from the heart and the pulmonary veins are carrying blood to the heart.

这个想法是成立的，因为我们看到肺动脉将血液从心脏带走，而肺静脉将血液带到心脏。

A backup of blood in the pulmonary veins and capillary beds can increase the pressure in the pulmonary artery and can also result in fluid moving from the blood vessels to the interstitial space causing pulmonary edema, or congestion.

而血液在肺静脉和毛细血管的积留，会提升肺动脉的压力，还会导致体液从血管流入组织间隙，引起肺水肿。

Oxygenated blood returns to the heart by way of pulmonary veins, which empty into the left atrium. Atrial contractions force blood from the left atrium through the mitral valve, also called bicuspid valve, into the left ventricle.

当心室收缩时，左室内血液经主动脉瓣流入主动脉¬----人体最大的动脉，为全身组织供血。
