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

富含氧的血被运往肺静脉、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，将更多的血通过肺静脉泵左房。

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。

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

富含氧气的血汇小静脉，最终进肺静脉；肺静脉将血左房。

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

这些肺静脉将含氧血输送到左房。

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室的低氧血，而肺静脉将来自于肺的富氧血运至左房。

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

血又一次在左房、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，肺静脉是将含氧血从肺输送到脏的大静脉。

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.

肺血管包括肺动脉及其分支以及毛细血管汇集而成的静脉（肺静脉及其属支）。

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.

血从脏右室，经过肺动脉到肺，再由肺静脉回到脏左房的行程，被称为肺循环。

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，房内和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。

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。

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，因为它们只是来自肺部，而肺动脉携带贫氧血，因为它们流向肺。

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从脏带走，而肺静脉将血带到脏。

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.

氧合血经肺静脉回流至脏，进左房。房收缩驱动左房血经二尖瓣进左室。

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.

而血在肺静脉和毛细血管的积留，会提升肺动脉的压力，还会导致体从血管流组织间隙，引起肺水肿。
