Human Body Bits

HUMAN BODY BITS

人体碎片

Which body bit matters most? I'm a cell. I may look simple- but even the most complicated bits of your body are made up of cells like me. In total you are made of about 37 trillion cells. 37,000,000,000,000 Different kinds of cell make up... ...your bones Without bones, you'd just be a blob of human on the floor. I wish people wouldn't walk all over me. ...your skin You definitely need skin. It keeps your insides inside you. Hey, you dropped your insides all over my new clean floor! ...your brain Without a brain, you wouldn't be able to do ANYTHING. Although, being able to do things and having a brain sometimes don't seem to go together! ...and every other body bit Some body bits are more important than others- but which is MOST important? Let's ask some body bits and see what they say. I'm the most important. I think you'll find it's me Oh dear, I don't think so Surely, it's me? No, No, NO!

哪个身体咬伤最重要？ 我是一个细胞。我可能看起来很简单，但即使是你身体最复杂的部分也是由像我这样的细胞组成的。 你总共由大约37万亿个细胞组成。 37,000,000,000,000种不同的细胞组成… ．．．没有骨头，你就只是地上的一坨人。 我希望人们不要对我颐指气使。 ．．．你的皮肤你绝对需要皮肤。 它能让你保持内在。 嘿，你把你的内脏撒在我干净的新地板上了！．．．没有大脑，你什么都做不了。 虽然，能够做事和拥有大脑有时似乎并不在一起！．．．有些身体部位比其他部位更重要——但哪一个是最重要的？ 我们去问一些身体部位，看看他们怎么说。 我是最重要的。我想你会发现是我哦，天哪，我不这么认为肯定是我？ 不，不，不！

Brain Mission control PAY ATTENTION! I'm in charge here. And this OBVIOUSLY makes me the most important. People say I'm bossy- but without me the others wouldn't know what to do. Just look at all the jobs I do... My important bits are cells called neurons. They do the thinking. Do you think people could survive without us neurons? Don't even think about it. Different parts of the brain do different things. Your brain helps you sense pain. Your brain helps sense the world around you- for example, through touching, seeing, smelling and hearing. I'm never going to open my brother's sock drawer again! Do you always dance like this? It's all my brain's doing! Your brain stores memories and works out challenges. Your brain helps you move (and dance), speak, breathe and eat.

大脑任务控制中心注意！这里我说了算。 很明显，我是最重要的。 人们说我很专横——但没有我，其他人就不知道该怎么办了。 看看我做的所有工作…… 我最重要的部分是神经元细胞。 他们自己思考。你觉得没有我们的神经元人类还能生存吗？ 想都别想。 大脑的不同部分做不同的事情。 你的大脑帮助你感知疼痛。 你的大脑帮助你感知周围的世界——例如，通过触觉、视觉、嗅觉和听觉。 我再也不会打开我哥哥放袜子的抽屉了！你总是这样跳舞吗？ 这都是我的大脑在做的！你的大脑储存记忆并解决挑战。 你的大脑帮助你移动（跳舞）、说话、呼吸和吃饭。

Eyes, ears and nose Sense organs Brain might THINK it's important- but where does Brain get its information? Us, that's where! Without us, you wouldn't know what was going on around you. Just think about all the things I do for you. I help you read this book, see tiny things close up and big things like that cow a long way away. I also warn you when something dangerous is coming. Ok, eyes are important. But ears do things that eyes can't. Ears let you hear what people are saying, listen to music, and warn you of danger even when you cannot see it. I don't want to stick my nose in, but... what about me? I tell you when food is good and air is clean. I even warn you about trouble ahead...

眼睛、耳朵和鼻子感觉器官大脑可能认为它们很重要——但是大脑从哪里得到这些信息呢？ 我们，就是那里！没有我们，你不会知道你周围发生了什么。 想想我为你做的一切。 我帮你读这本书，近距离看小事，远距离看大事情，比如那头牛。 当危险来临的时候，我也会警告你。 好吧，眼睛很重要。但是耳朵能做眼睛做不到的事情。 耳朵可以让你听到人们在说什么，听音乐，甚至在你看不到危险的时候警告你。 我不想多管闲事，但是…… 那我呢？我告诉你什么时候食物好，什么时候空气干净。 我甚至警告过你前方的麻烦……

Nervous system Sending messages How do all those show-off sense organs think their messages get to the brain? It's through me, your nervous system! Just look at what happens when you stub your toe... Here's what happened... Special cells in your toe, called pain receptors, turn on. The pain receptor releases a message. It passes along a nerve and up your spine. Fractions of a second later... Aargh!

神经系统发送信息这些炫耀的感觉器官是如何认为它们的信息到达大脑的？ 通过我，你的神经系统！看看你的脚趾碰到了会发生什么…… 事情是这样的……你脚趾上的特殊细胞，称为疼痛感受器，会被激活。 疼痛感受器会释放一个信息。 它沿着神经向上传递到脊柱。 不到一秒钟之后…… 啊呀!

Mouth The body's gateway I'm the gateway into your body for three things that keep you alive: air, water and food. Mouth forgets that I help you to bring in air too! Air is pulled into your mouth. Food and water go into your body through your mouth. Without me, most food would be impossible even to swallow. 1 First, the sharp teeth at the front bite off small chunks of food. 2 Next, the wide, flat teeth at the sides smash the food into a gloopy mess. While they do this, I release a slippery liquid called saliva. 3 The food mixes with the saliva and is ready to swallow. Getting air, food and drink into your body are pretty important jobs- aren't they?

我是你身体的入口，有三样东西是你赖以生存的：空气、水和食物。 大嘴也忘了我帮你吸气！空气被吸进嘴里。 食物和水通过你的嘴进入你的身体。 没有我，大多数食物都无法下咽。 首先，前面锋利的牙齿咬下小块的食物。 接下来，两侧又宽又平的牙齿把食物咬成糊状。 当它们这样做的时候，我释放一种叫做唾液的光滑液体。 食物与唾液混合，准备吞咽。 让空气、食物和饮料进入你的身体是非常重要的工作，不是吗？
