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.

而血在静脉毛细血管的积留，会提升动脉的压力，还会导致体从血管流入织间隙，引起肿。

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

血又一次在左心房、静脉、毛细血管淤积，最终导致高压肿。

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

富含氧的血被运往静脉、心脏，最后到织。

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

富含氧气的血汇入小静脉，最终进入静脉；静脉将血排入左心房。

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

紧急手术显示左静脉严重受伤。

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

毛细血管将这种富含氧气的血输送到静脉。

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

这些静脉将含氧血输送到左心房。

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，左室内血经主动脉瓣流入主动脉¬----人体最大的动脉，为织供血。

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，心房内心房周围的许多异位起搏点（通常是静脉根部附近）随机产生电脉冲。

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

血管收缩，将更多的血通过静脉泵入左心房。

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.

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.

静脉携带富氧血，因为它们只是来自部，而动脉携带贫氧血，因为它们流向。

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

有四条静脉，两条分别来自两个。

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周围的许多异位部位随机发起的，通常在静脉根部附近。

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，它要经过静脉，静脉是将含氧血从输送到心脏的大静脉。

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，因为我们看到动脉将血从心脏带走，而静脉将血带到心脏。
