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。

As equilibrium is always achieved across the respiratory membrane, the partial pressure will increase in the blood as well.

当平衡总是通过呼吸膜实现时，血液中的分压也会增加。

Oxygen and carbon dioxide move across the respiratory membrane, which includes the alveolus and pulmonary capillary.

氧气和二氧化碳穿过呼吸膜（包括肺泡和肺毛细血管）。

The respiratory membrane separates the alveolar air on one side from the blood on the other.

呼吸膜将一侧的肺泡空气与另一侧的血液分离。

Now, this respiratory surface is also referred to as the respiratory membrane.

现在，该呼吸表面也称为呼吸膜。

That diffusion occurs across the respiratory membrane, and it's directly proportional to the concentration gradient of the gas and pressure.

这种扩散发生在呼吸膜上，它与气体浓度梯度和压力成正比。

In summary, oxygen and carbon dioxide diffuse across a respiratory membrane.

总之，氧气和二氧化碳在呼吸膜上扩散。

This respiratory surface, also known as the respiratory membrane, includes the alveolar epithelial cells as well as the pulmonary capillary endothelial cells.

呼吸表面，也称为呼吸膜，包括肺泡上皮细胞和肺毛细血管内皮细胞。

Oxygen diffuses into the cells and does so until equilibrium is achieved across the respiratory membrane.

氧气扩散到细胞中，直到通过呼吸膜达到平衡。

External respiration refers to gas exchange across the respiratory membrane in the lungs.

外呼吸是指肺部呼吸膜上的气体交换。

In summary, gas exchange is the movement of oxygen into the blood and carbon dioxide out of the blood across the respiratory membrane in the lungs.

总之，气体交换是氧气进入血液，二氧化碳通过肺呼吸膜从血液中排出的过程。

Henry's law is applied to gas exchange as the partial pressures for oxygen and carbon dioxide equilibrate across the respiratory membrane.

Henry定律适用于气体交换，因为氧气和二氧化碳的分压在整个呼吸膜上达到平衡。

Internal respiration refers to gas exchange across the respiratory membrane in the metabolizing tissues, like your skeletal muscles, for example.

内呼吸是指在新陈代谢组织（例如骨骼肌）的呼吸膜上进行的气体交换。

Likewise, carbon dioxide equilibrates across the respiratory membrane, so the partial pressure of carbon dioxide in the blood leaving the lungs is only 40 mmHg.

同样，二氧化碳在整个呼吸膜上达到平衡，因此，血液中离开肺的二氧化碳分压仅为40 mmHg。

Furthermore, gases move across the respiratory membrane by diffusion, which is the movement of a substance from a high to a low concentration.

此外，气体通过扩散穿过呼吸膜移动，扩散是物质从高浓度到低浓度的移动。

It diffuses across the respiratory membrane, dissolves in the blood, and then enters the red blood cell, where it binds to hemoglobin.

它扩散穿过呼吸膜，溶解在血液中，然后进入红细胞，与血红蛋白结合。

The respiratory membrane is very thin, as it consists of only two cells - that is, the alveolar epithelial cell and the pulmonary capillary cell.

呼吸膜很薄，因为它只有两个细胞，即肺泡上皮细胞和肺毛细血管细胞。

It's important to note that gas exchange is directly proportional to the partial pressure gradient across the respiratory membrane, as partial pressure takes into account both concentration and pressure.

需要注意的是，气体交换与呼吸膜的分压梯度成正比，因为分压同时考虑浓度和压力。

It's important to note that, for each gas, the partial pressures equilibrate, or balance out, across the respiratory membrane, and they do so as the blood flows through the lungs.

重要的是要注意，对于每种气体，分压会在整个呼吸膜上达到平衡，血液流经肺部时也是如此。
