This is called gas exchange, swapping one gas for another.

这叫做气体交换，将一种气体交换成另一种气体。

As alveoli are responsible for gas exchange, this is not good news.

由于肺泡负责气体交换，这可不是好消息。

Heart failure. Respiratory gas exchange. People with holes in their stomachs. Nachos.

心力衰竭。呼吸气体交换。肚子上有洞的人。玉米片。

When this fluid builds up, it makes gas exchange inside the alveoli much more difficult.

当这些液体积聚起来后，就会使肺泡内的空气转换更加困难。

This is where the majority of gas exchange happens in the lungs.

这是大多数气体交换的地方。

Regardless of the cause, pulmonary edema interferes with gas exchange and results in shortness of breath.

无论病因是什么，肺水肿会干扰肺部换气，并导致气短气促。

And that allows us to provide gas exchange to the fetus, it's driven by the fetal heart.

样我们就可以在胎儿心脏的驱动下，为胎儿提供气体交换。

This is where the actual gas exchange occurs, and everything you find here has a form to suit that function.

这是实际气体交换发生的地方，你在这里找到的一切都有适合该功能的形式。

Now, that's a lot of gas exchange!

现在，这是大量的气体交换！

The inhaled smoke causes the walls of the alveoli to weaken and decrease in surface area, making gas exchange less efficient.

吸入的烟雾导致肺泡壁变弱，表面积减少，使气体交换效率降低。

The gases exchanged, oxygen and carbon dioxide, are referred to as respiratory gases.

气体交换，氧气和二氧化碳，被称为呼吸性气体。

Gas exchange in the metabolizing tissues is referred to as internal respiration.

代谢组织中的气体交换称为内呼吸。

Gas exchange occurs across this membrane and is diffusion of oxygen into and carbon dioxide out of the blood.

气体交换通过该膜发生，是氧气扩散到血液中以及二氧化碳从血液中扩散出来。

In summary, gas exchange must occur across a wet surface.

总之，气体交换必须在潮湿的表面上进行。

While the water is necessary for gas exchange, it creates surface tension that makes ventilation difficult.

虽然水是气体交换所必需的，但它会产生表面张力，使通气困难。

A thin layer of water lines the inside of our respiratory system and provides that wet surface for gas exchange.

我们的呼吸系统内部有一层薄水层，为气体交换提供了潮湿的表面。

The lungs are lined with a thin layer of water to provide a wet surface for gas exchange.

肺内层有一层薄薄的水，为气体交换提供一个湿润的表面。

Therefore, we use the term gas exchange, as oxygen is exchanged for carbon dioxide across the respiratory surface.

因此，我们使用气体交换这个术语，因为氧气在呼吸表面被交换成二氧化碳。

As we have stated, gas exchange occurs across a respiratory membrane.

正如我们所说，气体交换发生在呼吸膜上。

Gas exchange in the lungs, so oxygen moving from the alveoli into the blood and carbon dioxide from the blood into the alveoli are both great examples of diffusion.

肺部进行气体交换，因此氧气从肺泡进入血液和二氧化碳从血液进入肺泡都是扩散的很好的例子。
