Do Fetuses Poop? 胎儿会大便吗 The little scar in the middle of your abdomen marks the place where, for about nine glorious months, all the nutrients you needed to grow and develop and survive flowed straight into your bloodstream while you just floated around in a sac of amniotic fluid. 在你肚子上的那道小疤就是在约九个月的光辉岁月中，所有为了成长、发展 和生存所需的营养，在你刚浮在羊水的一刻起，进入你血流里的地方。 But have you ever wondered what was going on with your other bodily functions while you were in that enclosed space? To put it a little more bluntly, did you, you know, pee and poop in there? The answer to question #1 is yes, definitely: 但你有好奇过在那个密闭空间中，身体的其他机能怎麽了吗? 我直接地讲， 你会在里面尿尿和大便吗? 第一个问题的答案是: 没错，就是这样。 embryos start peeing after just two months of development, around the time they first begin swallowing--and, therefore, drinking--amniotic fluid. This does essentially mean that fetuses spend seven months drinking their own pee, but that's actually not as gross as it sounds. 胚胎在初期成长的两个月後开始尿尿，大概是胎儿第一次开始吞咽的时候，所以 会因此喝到羊水。这基本上代表胎儿有七个月的时间都在喝自己的尿，但这没 有听起来的这麽恶心。 For one thing, urine--unlike feces--is sterile, so it doesn't contain bacteria that could make the fetus sick. Also, the waste products we normally get rid of by urinating, like excess nitrogen, are instead filtered from the fetus and delivered, through the umbilical cord, back to the mother for disposal. 其中一个原因是，他们的尿液不像一般的排泄物带有病菌，不会使胎儿致病。还有， 我们经由小便排掉数种废弃物，像是过量的氮。胎儿则是藉由脐带过滤和输送废物回 母体处理。 And what about the waste we normally get rid of by pooping? Well, mom takes care of that, too -- indirectly. She digests food before it gets to the baby, absorbing nutrients like sugar and protein into her bloodstream and then passing those nutrients to her fetus through the umbilical cord. So most of the potential poop products stay with the mother. 那对於我们透过大便排出的废物呢? 这个妈妈也帮我们--间接地处理好了。在食物 被送给宝宝前妈妈会先消化过，吸收其中的醣类和蛋白质之类的养分到她的血流里， 之後再经由脐带送给她的胎儿。所以大多数的潜在大便都会留在妈妈体内。 The fetus's digestive system isn't totally empty though, some waste does go there and get broken down by acidic bile in the small intestines, producing a slimy, sticky greenish mass called meconium. But, unlike the large intestine of everyone outside a womb, a fetus's large intestine is mostly sterile and devoid of the billions of bateria that break down our waste and make up as much as 50% of the brown pulp known as feces. 但胎儿的消化系统也不尽然是空的，还是会有些许的废物进入，在小肠内被胆汁酸分解 ，产生一种叫做胎便的黏稠绿色物质。不像每个出生後的人，胎儿的大肠大部分是无菌的 ，缺少数十亿个分解我们废物的细菌，这些细菌占了我们排遗物的百分之五十。 So the green sticky mass that forms in a fetus's small intestines eventually becomes a green, sticky, and mostly bacteria-free mass inside the baby's first dirty diaper. And in a way, it's the first and last clean poop in anyone's life. 所以这个在胎儿小肠里形成的黏黏绿色物质，最终会变成宝宝第一片尿布上的一团绿色、 黏稠且近乎无菌的东西。某种程度上，这就是任何人生命中最初也是最後的乾净大便。 --------------------------------------------------------------------------- https://www.youtube.com/watch?v=qc-244lKjjM 有翻译不顺或是错误的翻译麻烦大家纠正了，谢谢! --
