As the cancer cells move into the epithelium, there's inflammation which brings extracellular fluid out through breaks in the skin.

随着癌侵犯上皮，会有炎症导致液从皮肤的破口带出。

Diuretics also decrease the extracellular fluid (ECF) volume, and are primarily used to produce a negative extracellular fluid balance.

利尿剂也减少液(ECF)的体积，主要用于产生负向液平衡。

In the body, most calcium is located in bones, only about 1% is in the blood and extracellular fluid.

在体，大多数钙都位于骼中，只有约1％位于血液和液中。

Hypokalemia may result from increased excretion inadequate intake or shift to potassium from the extracellular fluid into the cells.

钾血症可能是由排泄增加，摄入量不足或钾从液转移到所致。

In order for our cells to work properly, systems had to develop that could regulate the concentration of salt and other components of our blood and extracellular fluid.

为了使人体正常工作，身体的各个系统必须能够调节盐以及血液和液体其他成分的浓度。

In normal circumstances, more than ninety percent of the total body potassium is intracellular, the remaining is in the extracellular fluid and blood plasma.

正常情况下，全身90%以上的钾位于钾，其余的位于液和血浆。

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.

考虑到无法在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。

This is achieved by two mechanisms: excretion of potassium through the kidneys and intestines with the kidneys playing a predominant role, shifting of potassium from the extracellular fluid into the cells by the sodium potassium pump.

钾通过肾脏和肠道排泄，肾脏起主要作用，钾通过钠钾泵从液转移到。
