Voice 1: These eggs enter different parts of the person's body. They enter the intestines. And they enter the bladder. This is where the body keeps liquid waste, urine. Some of these eggs are expelled from the body, in human waste. Over their life, these eggs will infect many other people.
声音1：这些卵会进入人体的不同部位。它们会进入肠道。还会进入膀胱。膀胱是人体储存废液——尿液——的地方。一些卵会随着人类的排泄物被排出人体。这些卵的一生能影响许多其他人。
Voice 2: But not all of the eggs leave the body. Some are trapped in the digestive system and the urinary system. The digestive system is the body's organs that process food — including the stomach, liver, and intestines. It also includes the systems that process solid human waste. The urinary systems process liquids, in particular, liquid waste. The eggs trapped in these systems begin to cause problems. The person's body reacts to the eggs. It tries to protect itself. And by protecting itself, it causes other problems.
声音2：但并不是所有卵都会离开人体。一些卵会留在消化系统和泌尿系统中。消化系统是人类处理食物的器官，包括胃、肝脏和肠道。消化系统还包括处理人类固体废物的系统。泌尿系统是处理液体、尤其是废液的器官。卵会留在这些系统中，然后开始制造问题。人体会对这些卵做出反应。人体会试图保护自己。但在保护自己的过程中，会引发其他问题。
