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

富含氧被运往肺静脉、心脏，最后到全身组织。

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

富含氧气汇入小静脉，最终进入肺静脉；肺静脉排入左心房。

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

毛细这种富含氧气输送到肺静脉。

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

肺收缩，更多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.

这些肺静脉含氧输送到左心房。

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心室低氧，而肺静脉来自于肺富氧运至左心房。

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

又一次在左心房、肺静脉、肺毛细淤积，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，肺静脉是含氧从肺输送到心脏大静脉。

The heart pumps blood through two circuits. The right side of the heart pumps blood to the lungs to be oxygenated through the pulmonary circuit.

肺包括肺动脉及其分支以及毛细汇集而成静脉（肺静脉及其属支）。

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，心房内和心房周围许多异位起搏点（通常是肺静脉根部附近）随机产生电脉冲。

This trip from the right ventricle of the heart, through the pulmonary artery to the lungs, and back to the left atrium of the heart is called the pulmonary circulation.

从心脏右心室，经过肺动脉到肺，再由肺静脉回到心脏左心房行程，被称为肺循环。

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，因为它们只是来自肺部，而肺动脉携带贫氧，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，这些电脉冲是从心房内和周围许多异位部位随机发起，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，因为我们看到肺动脉从心脏带走，而肺静脉带到心脏。

Blood that enters the pulmonary artery is carried to the lungs. There it undergoes oxygenation, a process in which carbon dioxide (a waste product of cellular metabolism) is exchanged for oxygen from the environment.

氧合经肺静脉回流至心脏，进入左心房。心房收缩驱动左房经二尖瓣进入左室。

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.

而在肺静脉和毛细积留，会提升肺动脉压力，还会导致体从流入组织间隙，引起肺水肿。
