As you experience periods of low oxygen intake, your body releases stress hormones.

当你不时经历氧气摄入量过低时，你的身体会释放压力荷尔蒙。

But, for example, if I looked at, fetal hemoglobin relinquishes that oxygen at lower oxygen tensions.

但是，举个例子，如果我看到，胎儿血红蛋白在较低的氧张力下放弃氧气。

For example, tumors have low oxygen and pH levels and over-produce specific molecules.

举个例子，肿瘤通常含氧量低，PH 值低，并且会过量生产特定分子。

The lower oxygen pressure found in an aircraft cabin is equivalent to that at 6,000-8,000 feet of altitude.

机舱内的低氧压相当于6000至8000英尺高度的氧压。

There's lower oxygen pressure at higher altitudes, which means there's less oxygen available to transfer to the lungs.

高海拔地区的氧气压力较低，这意味着输送到肺部的氧气较少。

It is why people with lower oxygen concentration sometimes remove protective clothes atop Mount Everest; some freeze to death.

这就是为什么缺氧的人有时会在珠穆朗玛峰顶上脱下防护服；其中一些人甚至会因此冻死。

Well in response to low oxygen levels, or hypoxia, the pulmonary arterioles constrict, which raises the pulmonary blood pressure.

为应对低氧水平或缺氧，肺小动脉会收缩，这就容易引起肺高血压。

Alcohol's effects are more pronounced 30,000 feet above ground, even in a pressurised cabin, because of lower oxygen levels.

酒精的作用在离地3万英尺的高空更加明显，在加压的机舱里也会更明显，因为氧气水平较低。

The low oxygen levels might force the whales' prey towards the surface, where oxygen is a bit more plentiful.

低氧水平可能迫使鲸鱼的猎物升至海面，因为海面的含氧量更为充足。

But a wine-making set-up keeps the oxygen levels low so that yeast consume sugar using fermentation, the anaerobic pathway.

不过制酒装置保持低氧含量从而保证酵母 通过发酵分解糖分，即厌氧途径。

Only one specific cell type was affected by the low oxygen.

只有一种特定的细胞类型受到低氧的影响。

For animals, low oxygen is generally bad.

对于动物来说，低氧通常是不好的。

Low oxygen levels were discovered and began to affect the group's health.

发现低氧水平并开始影响该组的健康。

And what that means is more phytoplankton and more sinking sails and lower oxygen.

这意味着更多的浮游植物和更多的下沉帆和更低的氧气。

People with chronic bronchitis also often present with hypoxemia, low oxygen in the blood, and hypercapnia, increased carbon dioxide in the blood.

慢支患者经常合并有低氧血症，即血中氧气含量低，以及高碳酸血症，即血中二氧化碳含量高。

Authorities there are also dealing with low oxygen supplies, a highly transmissible variant, and only 11% of the country being fully vaccinated.

同时，该国有关部门处理的问题还包括氧气供应不足、具高度传染性的病毒变种，以及全国只有11%的人口接种了疫苗等。

Within minutes or even seconds of reaching altitudes of 1,500 meters, carotid chemoreceptors in your neck sense your blood's low oxygen pressure.

如果在几分钟甚至几秒钟内到达 1500 米以上的海拔，脖子里的颈动脉化学感受器就会察觉到血液氧气压力过低。

The researchers found that around 700 ocean sites are now suffering from low oxygen compared with 45 in the 1960s. Matt McGrath reports.

研究人员发现，现在约有700处海域缺氧，相比之下，上世纪60年代只有45处。以下是马特·麦格拉思的报道。
