So the algae cells, which are only 20 nanometers across -- about 5000 times smaller than the width of a human hair -- bounce around between your cells harmlessly, until they bump into a cancer cell, where they lock on.

因此，些藻类细胞直径仅有20纳米——大约比人类头发的宽度小5000倍——它们在你的细胞之间无害地游走，直到碰到癌细胞， 然后就会锁定目标。

Second, cytokines travel through the body to the hypothalamus, the part of the brain responsible for controlling temperature, thirst, hunger, and sleep, among other things.

其次，细胞因子在体内游走到下，是大中负调控体温、口、和睡眠等功能的区域。

First Paradileptus immobilizes the rotifer with fired toxicysts and the animal is swallowed by the single-celled organism as it swims away.

首先，Paradileptus 用发射的毒囊固定住轮虫，当它游走时，轮虫被单细胞生物吞噬。

Similar to how the venom disrupted how the fish cells communicated and the fish couldn't swim away.

类似于毒液如何破坏鱼细胞的交流方式，鱼无法游走。

These cells (called macrophages) roam around our bodies looking for potential trouble (e.

些细胞（称为巨噬细胞）在我们体内游走，寻找潜在的麻烦（例如。

Now that was happening because the toxins in the venom were attacking how the fish's cells communicate with each other, preventing it from swimming away.

现在发生种情况是因为毒液中的毒素正在攻击鱼细胞之间的交流方式，阻止它游走。

As they move around, leukocytes work like security personnel, constantly screening the blood, tissues, and organs for suspicious signs.

白血细胞如同巡逻的安保人员， 在体内四处游走，持续对血液、组织和器官进行筛查，寻找可疑迹象。
