Chapter 1: What's Under Your Skin? Hello! My name is Dr. Ick, and this is my friend, Sam. We like to study things that are sticky, icky, and disgusting! In our years of studying, we have never come across anything more gross than... THE HUMAN BODY!

第一章：你的皮肤下面有什么？ 大家好呀！ 我是伊克博士，这是我的朋友萨姆。 我们最喜欢研究黏糊糊、脏兮兮、恶心兮兮的东西啦！ 研究了这么多年，我们还没见过比什么东西更恶心的呢…… 那就是人类的身体！

There are a lot of yucky, fun facts we know about the body! For example, do you know which long, slippery tube moves all the food and drink in our bodies? It's the intestines (say: in-TEH-stuhns). Everything we eat gets digested, or broken down, in the large and small intestines so that our bodies get the fuel they need. When stretched out, the large intestine can measure up to five feet long. But the small intestine can measure up to twenty-five feet long! SMALL INTESTINE 25 FEET LARGE INTESTINE 5 FEET

我们知道好多关于身体的又恶心又好玩的冷知识哦！ 比如说，你知道是哪根长长的、滑溜溜的管子负责运输我们吃进去的所有食物和饮料吗？ 就是肠道哦（读音：cháng dào）。 我们吃的所有东西都会在大肠和小肠里被消化，也就是被分解，这样身体才能获得需要的能量。 要是把大肠拉直的话，它能有1.5米那么长哦。 可小肠拉直的话居然能有7.6米那么长！ 小肠 7.6米 大肠 1.5米

Do you know what the biggest organ in the body is? The skin! The skin is an organ? Yes! And it does a lot of work. The skin can shed up to two hundred million skin cells every single hour!

你知道人体最大的器官是什么吗？ 是皮肤呀！ 皮肤居然是器官？ 当然啦！ 它可承担了好多工作呢。 皮肤每小时居然能脱落多达2亿个皮肤细胞哦！

Our blood is located underneath our skin. It travels through long, skinny tubes called veins (say: VAYNS). Veins are blood vessels that carry blood from different parts of our bodies to our heart. They can stretch out more than sixty thousand miles. That would circle the Earth almost two-and-a-half times!

我们的血液就在皮肤下面流动。 它会在叫做静脉的细长管道里流动（读音：jìng mài）。 静脉是血管的一种，负责把血液从身体各个部位输送回心脏。 把所有静脉拉直连起来能超过9.6万公里。 都差不多能绕地球两圈半啦！
