4 Going Around in Circles

Chapter 4 GOING AROUND IN CIRCLES Uncle Al rubbed his chin. "Hmmmm…," he murmured. "You guys are in my circulatory system." "Circulatory system!" said Judy. "That means we're going around in circles inside you." Uncle Al nodded. "Blood does go in circles. Very predictable. "Do you have any idea where you are now?" meep… "Blood is dark," said Thudd. "Going back to heart." "Ah!" said Uncle Al. "You're in a capillary headed to a vein now. Veins are the tubes that send blood to the lungs to get oxygen. Arteries are the

艾尔叔叔揉了揉下巴。 “嗯……”他低声说。“你们在我的血液循环系统里。” “循环系统！”朱迪说。 “这意味着我们在你体内兜圈子。” 艾尔叔叔点点头。“血液确实会循环。 可预测的。“你知道你现在身在何处吗？” “回到心脏。”“啊！”阿尔叔叔说。 “你现在在通往静脉的毛细血管里。 静脉是将血液输送到肺部获取氧气的管道。 动脉是

tubes that send blood filled with oxygen to the body. "Soon you'll get to my lungs," said Uncle Al. "Then you can crawl out of a capillary, into my lungs, and start climbing up. "You'll get to my windpipe, the air tube that goes from my lungs to my nose. You climb up that and then, uh, crawl into my mouth." "Eeeew!" Judy groaned. "That is soooo disgusting!" Uncle Al chuckled. "Not more disgusting than getting flushed down the toilet, right? You've done that before. "Uh-oh," said Uncle Al. "I'm having a power problem with the… I'll try to… and… back to… "Hang… get to… heart. It… be… rough…" Uncle Al disappeared, except for his lips. They were still moving. But Andrew and Judy couldn't hear a word. Then with a small pop, Uncle Al's lips disappeared.

将充满氧气的血液输送到身体的管道。 “很快你就会摸到我的肺，”阿尔叔叔说。 “然后你可以从毛细血管里爬出来，进入我的肺部，开始往上爬。 “你会看到我的气管，也就是从肺到鼻子的气管。 你爬上去，然后，呃，爬进我嘴里。” “也!”朱迪呻吟着。“这太恶心了！”阿尔叔叔笑了。 “不会比被冲进马桶更恶心吧？” 你以前做过。“哦哦，”阿尔叔叔说。 “我的……电源出了问题，我会试着……然后……回到……”挂……挂……到……心脏。 阿尔叔叔消失了，只剩下他的嘴唇。 他们还在移动。但安德鲁和朱迪一个字也听不见。 接着，“啪”的一声，艾尔叔叔的嘴唇消失了。

The narrow capillary was opening into a wider passageway. Red blood cells no longer rushed along in single file. Now crowds of them were tumbling through the chicken-soupy plasma. thumpa… thumpa… thumpa… It was Uncle Al's heart beating. White blood cells rushed like speeding jellyfish among the red cells. A giant white blood cell whammed into Andrew's and Judy's red-blood-cell disguises and flung them apart. "Androooooo!" hollered Judy. Andrew tugged the Drastic Elastic sharply. The next instant, Judy's head banged against Andrew's.

狭窄的毛细血管正在向更宽的通道打开。 红细胞不再排成一列向前冲。 现在，一群人在鸡汤般的血浆中翻滚。 咚咚……咚咚……咚咚……那是艾尔叔叔的心跳。 白细胞像水母一样在红血球中奔涌。 一个巨大的白细胞撞击了安德鲁和朱迪的红细胞伪装，把他们分开了。 “安德鲁——”朱迪叫道。 安德鲁猛拉了一下弹力绳。 紧接着，朱迪的头撞到了安德鲁的头上。

"Youch!" hollered Judy. "See?" said Andrew. "All I have to do is give the Drastic Elastic a big jerk." "You're the big jerk, Bug-Brain!" said Judy, rubbing her head. thumpa… thumpa… thumpa… thumpa… THUMPA… Now Andrew didn't just hear the sound, he could feel it pounding like a drum. "Uncle Al's heartbeat sounds really loud," said Andrew. "We must be getting close to his heart." The blood river sped them along. Through the plasma and red blood cells, Andrew thought he saw giant pink tent flaps! They sprung open. Then they instantly slammed shut. meep… "Flaps called heart valve," said Thudd. "Heart valve let blood into heart." "What makes them open and close?" asked Andrew. meep… "Electric signal," said Thudd. "Kinda like electric signal open garage door."

“嘿！”朱迪大声叫道。“看到了吗？”安德鲁说。 “我要做的就是用力拉一下弹力裤。” “你真是个大混蛋，笨蛋！”朱迪揉着头说。 砰砰，砰砰，砰砰，砰砰，砰砰，砰砰，现在安德鲁不仅听到了声音，他还能感觉到像鼓一样的砰砰声。 “阿尔叔叔的心跳听起来真的很响，”安德鲁说。 “我们一定是接近他的心脏了。” 血河加速了他们的前进。 透过血浆和红血球，安德鲁仿佛看到了巨大的粉色帐篷盖！它们突然打开了。 然后他们立刻关上了。 “叫心脏瓣膜的瓣膜，”泰德说。 “心脏瓣膜让血液进入心脏。” “是什么让它们打开和关闭的？”安德鲁问。 “电信号。”泰德说。 “有点像打开车库门的电子信号。”

The next second, the heart flaps opened again. Andrew and Judy were sucked into a huge dark cave. meep… "Inside heart now!" said Thudd. Bzzzzzzzt… A powerful tingle zipped from Andrew's head to his toes. "Oofers!" he yelled. "I got an electric shock!" meep… "Electricity come from Unkie Al's heart," said Thudd. "Part of heart called pacemaker. Pacemaker send electric signal to open heart valve. Send signal to make heart beat." "We got shrunk by an electric shock," said Andrew. "If this shock makes us any smaller, we'll totally disappear!"

下一秒，心脏又打开了。 安德鲁和朱迪被吸进了一个又大又黑的洞里。 “现在往心里去！” 一阵强烈的刺痛从安德鲁的头传到脚趾。 “哎哟！”“电流来自昂基·阿尔的心脏。” “心脏的一部分叫做起搏器。 起搏器发出电信号打开心脏瓣膜。 发出信号使心脏跳动。” “我们被电击缩小了，”安德鲁说。 “如果这个冲击让我们变得更小，我们就会完全消失！”
