Pulmonary Veins
肺静脉
And in this tutorial, we will discuss the pulmonary veins, their location, and their function. The topic is fairly simple and straightforward with one very important exception.
在这个教程中，我们将讨论肺静脉及其位置和功能。这一节相当简单易懂，但需要注意一个非常重要的难点。
The exception is that, any other time we use the term vein, we’re discussing a vessel that carries deoxygenated blood. But in the case of the pulmonary veins, they are carrying oxygenated blood.
这一难点是，每当我们使用术语“静脉（vein）”时，我们都将讨论的是携带脱氧血液的血管。但是，肺静脉携带的是含氧血液。
There are four pulmonary veins in total, two connected with each lung.
肺静脉有 4 条，每个肺各与两条肺静脉连接。
The right pulmonary veins, seen here from a posterior view, carry blood from the right lung into the left atrium of the heart where it is distributed to the rest of the circulatory system. They are the right inferior pulmonary vein and the right superior pulmonary vein.
从后视图观察，右肺静脉将血液从右肺输送到心脏的左心房，然后分布到循环系统的其余部分。它们是右下肺静脉和右上肺静脉。
The left pulmonary veins carry blood from the left lung into the left atrium of the heart where it continues to flow outward to the rest of the body.
左肺静脉将血液从左肺输送到心脏的左心房，然后继续向外输送到身体的其他部位。
The two left pulmonary veins are also named for their location: the left inferior pulmonary vein and the left superior pulmonary vein.
两条左肺静脉也根据其位置命名，它们是左下肺静脉和左上肺静脉。
Here’s one way to remember.
我们有一种记忆方式：
All veins carry blood to the heart, and all arteries carry blood away from the heart, right? Well, it’s the same here except that the pulmonary veins carry blood to the heart from the lungs, so it’s oxygenated.
所有的静脉都将血液输送到心脏，所有动脉都将血液带离心脏，对吧？肺静脉也是如此，但是它是将血液从肺输送到心脏，所以是血液是含氧的。
When you hear the term pulmonary vein, think of it as self-describing. Think lung to heart. And that should help jog the memory.
当听到术语“肺静脉（pulmonary vein）”时，我们可以尝试想象，它将血液从肺输送到心脏。这应该有助于记忆。
