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.

血液从脏右室，经过动脉到，再由静脉回到脏左的行程，被称为循环。

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.

而血液在静脉和毛细血管的积留，会提升动脉的压力，还会导致体液从血管流入组织间隙，引起。

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

血液一次在左、静脉、毛细血管淤积，最终导致高压和。

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静脉、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.

富含氧气的血液汇入小静脉，最终进入静脉；静脉将血液排入左。

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液输送到静脉。

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

这些静脉将含氧血液输送到左。

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.

颤时，内和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。

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.

血管包括动脉及其分支以及毛细血管汇集而成的静脉（静脉及其属支）。

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

血管收缩，将更多的血液通过静脉泵入左。

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.

氧合血经静脉回流至脏，进入左。收缩驱动左血液经二尖瓣进入左室。

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.

静脉携带富氧血液，因为它们只是来自部，而动脉携带贫氧血液，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.

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

Pulmonary vessels include the pulmonary artery and its branches, and the veins that drain the lung capillaries.

动脉携带来自于右室的低氧血液，而静脉将来自于的富氧血液运至左。

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，静脉是将含氧血液从输送到脏的大静脉。

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液从脏带走，而静脉将血液带到脏。
