The example I'll talk about in this podcast is the excretory system.

在本期播客中，我将探讨的例子是系统。

The kidneys are the most important excretory organ.

肾脏是最重要的官。

An example would be the kidney and the bladder working hand in hand in the excretory system.

一个例子就是肾脏和膀胱在系统中协同工作。

The example I'll talk about, if I can start talking right, is excretory system.

我要讨论的例子，如果我能开始讲的话，就是系统。

We can see that the excretory system in flatworms, earthworms and finally in vertebrates serve the same purpose.

我们可以看到，扁虫、蚯蚓以及最终脊椎动物的系统，都服务于相同的目的。

And so those are part of the excretory system.

这些都是系统的一部分。

And so we can see continuity in this excretory system and this tubule of a flatworm, earthworm, and vertebrates.

因此，我们可以在扁形虫、蚯蚓和脊椎动物的系统及其管状结构中看到连续性。

It requires awareness of bladder fullness, self-control to override excretory reflexes, selection of a latrine, and intentional relaxation of the muscles which control the flow of urine.

它需要牛意识到膀胱充盈、控制反射、选择厕所以及有意识地放松控制尿流的肌肉。

In fact we would put the ureters, which is going to be this right here, as a part of the excretory system as well.

事实上我们会把输尿管， 也就是这里这个部分，也视为系统的一部分。

First one, and in us, the big part of our excretory system is the kidney, the first thing it does is it maintains osmolarity of the blood.

首先， 在我们人体中， 系统的主要部分是肾脏，其首要功能是维持血液的渗透压。
