Fortunately, their gills have evolved ways to excrete the excess salt from their body.

幸运的是，它们的鳃已经进化出了排出体内多余盐分的方式。

Saltwater fish, and other ocean creatures evolved to be able to drink saltwater to stay hydrated, and get rid of excess salt.

咸水鱼和其他海洋生物进化到得以摄入盐水吸收水分，并排出多余的盐分。

19. Another adaptation to the salty environment is the ability to excrete excess salt back into the environment.

它们适应环境的另一项进化是排除超量盐分的能力。

The extra fluid would increase the amount of urine and allow the body to get rid of the excess salt.

额外的液体会增加尿量，让身体排出多余的盐分。

Not all sea creatures do this the same way, but, being able to pump out excess salt is crucial to surviving in the ocean.

并非所有的海洋生物吸收水分和排出盐分的方式都一样，但是，能排出多余的盐分对于生存在海洋中来说至关重要。

Not all sea creatures do this the same way but being able to pump out excess salt is crucial to survive in the ocean.

虽然并不是所有生物都以相同的方式（生活），但能排出盐分，对于在海洋中生存仍然至关重要。

So, If it's easier for the body to handle excess salt rather than insufficient salt, we should expect to have data showing higher rates of mortality from lower salt intake.

所以，相比却盐的情形，人体在应对盐过量时会更从容些，我们应该期望有相关数据显示，低盐摄入导致的死亡率较高。

Considering cells can't survive outside a narrow range of electrolyte levels in the extracellular fluid, the ability to retain salt and at the same time excrete excess salt is very important.

考虑到细胞无法在细胞外液中电解质水平范围较窄的情况下存活，在保留盐的同时排出多余盐的能力就显得至关重要。

Reptiles today that live in saltwater, like crocodiles and sea turtles, have salt glands in their eyes, nose, or mouth that remove excess salt from their blood and prevent an overload of sodium.

今天生活在盐水中的爬行动物，如鳄鱼和海龟， 在它们的眼睛、鼻子或嘴巴中都有盐腺，可以去除血液中多余的盐分， 防止钠超载。
