The CFTR protein is a channel protein that pumps chloride ions into various secretions, those chloride ions help draw water into the secretions, which ends up thinning them out.

CFTR蛋白是一种可以将氯离子泵入分泌物的通道蛋白，氯离子可以使水分渗入分泌物，对它们进行稀释。

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和泵送钾离子来维持的，对吗？

The cells pump these ions into a hollow tube that runs through the sweat gland.

细胞将这些离子泵入穿过汗腺的中空管中。

This balance is maintained by the sodium-potassium pump, which pumps 2 potassium ions in for every 3 sodium ions out, as well as potassium leak channels and inward rectifier channels that are scattered throughout the membrane.

这一平衡由钠-钾离子泵维持，它每泵入2个钾离子时，会泵出3个钠离子，此外还有贯通细胞层的钾泄露通道和整流通道。
