UnbeLEECHable! 神奇的水蛭!

Why do leeches have MANY brains???

And by many, I don’t mean 4, 5, 7 or 10.

I MEAN 32 brains!!!!!!

Yes, be stupefied. Be shocked. Leeches REALLY have 32 brains! And we humans have only 1 brain.

And we’re SMARTER.

Actually, even though leeches have that many brains, they don’t function exactly like a human brain. So don’t expect leeches to construct an atomic bomb anytime soon. Which is a good thing, by the way.

Leeches not have only 32 brains, but they have 3 JAWS!!! And each has 115-120 teeth.

No wonder leeches can suck a lot of blood. They can gorge themselves up to five times their own body weight in pure, red blood! Sounds vampire-scary, doesn’t it?

However, have no fear. Leeches aren’t really bad creatures. They really aren’t. In fact, they can help save your limb. Or even your head (probably). But they can save your LIFE (more importantly!).

Leeches were first used in medicine about 1000 B.C.. And now leeches are used for biosurgery. Biosurgery is a surgery in which biological agents (such as leeches) are used. They are used as a research tool too nowadays.

So how can a leech save your life, you ask? Well, let’s say that you sort of tore your arm off (not recommended), and you need surgery to reattach your arm back. During the surgery, blood is carried through your arteries to your wound area.

And if your veins haven’t healed, a bad congestion can happen. And this puts you in a risk.

So the leech comes and sucks every drop of blood to prevent that congestion! And the best part is … you DON’T feel pain!!!!!! Great, isn’t it? That is because leeches have their own natural anesthetic.

Isn’t that miraculous, considering that the scary leech has 32 brains and 3 jaws?

We really have to salute leeches.They CAN save a LIFE!

Not bad for a creature whose 32 brains are useless.


为什么水蛭有很多颗脑袋？？？

不只是4颗、5颗、7颗或10颗脑袋而已。

而是有32颗脑袋！！

不要太震惊哦。水蛭真的有32颗脑袋呢！而我们人类只有1颗脑袋。

但我们比较聪明。

其实，虽然水蛭有很多颗脑袋，但它们脑袋的功能却不像人类的脑袋那么好。因此，不必期待水蛭能在短时间内建造出一颗原子弹哦。这或许也是一件好事。

水蛭不只有32颗脑袋，还拥有3个颌骨！！！而且每个颌骨各有115至120颗牙齿。

水蛭如此特殊的构造，使它可以吸食很多人类的血液，也就不足为奇了。它们可以吸食自己体内充足的血液达五次！听起来像吸血鬼似的，可怕吧?

然而，我们不需感到害怕。水蛭其实不是有害的动物。它们真的不是。事实上，它们可以帮助救你的肢体，甚至你的头。更重要的是，它们可以救你的性命。

大约公元前1000年，水蛭首先被用于医学上。现在水蛭则适用于生物外科医学方面。生物外科医学是一种使用生物制剂（如水蛭）的手术。如今，水蛭被用来作为一项研究工具。

那么，你是否想知道水蛭如何拯救你的生命呢？我当然不建议你撕断自己的手臂，只是假设你的手臂受伤了，需要动手术来重新接驳回它。在外科手术中，血液是通过你的动脉流向你的伤口部分。

如果当时你的静脉还没有完全愈合，或许就有可能使血管发生不良的挤塞情况，而这可能会让你拥有生命危险。

因此，水蛭就会被用来吸食血液，以防止继续出现挤塞的情况！而你可能并不觉得痛！！难以想像吧？这是因为水蛭本身拥有天然麻醉剂。

想像一下惊人的水蛭竟有32颗脑袋和3个颌骨，这难道不是奇迹吗？

我们真的要向水蛭致敬.它们足以拯救一条人命！

水蛭拥有32颗无用的脑袋，似乎也是不错的。
