Even bananas contain trace amounts of a radioactive potassium isotope.

即使是香蕉都含有微量的放射性同位素。

Finally, don't forget about potassium-rich foods like bananas, salmon and plain yogurt.

最后，不要忘记富含的食物，如香蕉、鲑鱼原味酸奶。

It's not subject to the postmortem potassium build-up.

Geochemical analysis of the Chang'e-6 lunar samples has shown that their concentration of trace elements such as thorium, uranium and potassium is markedly different from the samples retrieved by the Apollo missions and the Chang'e-5 mission.

对嫦娥六号月球样本的地球化学分析显示，其微量元素如钍、的浓度与阿波罗任务嫦娥五号任务所回收的样本有显著不同。

" The relationship between potassium and cardiovascular events was the same regardless of salt intake, suggesting that potassium has other ways of protecting the heart on top of increasing sodium excretion."

“无论摄入多少盐，与心血管疾病之间的关系都是相同的，这表明除促进钠的代谢外，还有其他保护心的方法。”

The low potassium or hypokalemia is particularly worrisome because it can lead to muscle weakness and even cardiac arrhythmias, the latter of which can lead to death.

其中低血是尤其危险的，因它能导致肌无力甚至心律失常，后者可危及生命。

These pumps drive potassium from the blood into the cells and from there it flows down its concentration gradient into the tubule to be excreted as urine.

这些泵驱使从血液进入细胞内，细胞内的离子再顺着浓度梯度进入肾小管，以尿液形式排泄。

To accomplish this, cells use a complex series of multiple ion channels, exchangers, and pumps to exchange hydrogen ions for potassium ions across the cell membrane.

完成这一步骤，细胞利用一种特殊的离子转运体，在细胞膜两侧进行氢离子离子的交换。

他不知道何这名年轻人体内的含量如此之低，但他知道如果不能提高这名年轻人的含量，他可能会死亡。

In most cells, the action potential starts with the resting potential, which the cell maintains by pumping sodium ions out and potassium ions in, Right?

在大多数细胞中，动作电位是从静息电位开始的，静息电位是细胞通过泵送钠离子泵送离子来维持的，对吗？

Luckily, our bodies have an amazing ability to recover and once she quit, her potassium levels and other complications began to rebound.

So did the increase in potassium or the increase in sodium improve their health?

那么，到底是的增加还是钠的增加改善他们的健康呢？

Cells in the heart depend on the flow of potassium to work properly.

心细胞依靠的流动来正常工作。

The potassium is then excreted, so over time, even though the blood potassium levels remain high, overall stores of potassium in the body —which includes potassium inside cells—starts to run low.

离子之后会被排出，一段时间过后，即使血液中的含量很高，体内总共的含量（包括细胞内）会开始下降。
