We've talked about one the main concepts in physiology being homeostasis, that is 'how do you maintain a constant internal environment?
我们讲到了生理学的主要概念,内稳态,即如何维持内环境的稳定
-
So, these are all involved with our ability to maintain homeostasis by exchanging materials with the external environment.
这个过程关乎人体维持内稳态的能力,内稳态通过与外环境进行物质交换来实现

Banks are institutions that exist within the community, and they live among the business people in the community and have an ongoing relationship with them.
银行是存在于一定社会环境中的机构,它存在于这个社会环境内的商企人士之中,并和他们之间保持着联系

And so one could say that there is a very unfortunate mismatch between our biology and our evolution and the modern food environment, because biology of course takes thousands and thousands, millions of years even to change, but the food environment has changed relatively recently.
可以说,在人类的生物进化和现在的,食品环境之间存在着非常不幸的脱节,生物学上的改变要花上,成千上万年的时间,但是食品环境却可以在短时间内迅速改变

Of course when molecules get absorbed through the intestinal tract they become part of your internal environment.
当然,分子在被肠道吸收后,就成为身体内环境的一部分
-
In order for life to proceed, you need to maintain a constant internal environment.

Well that process of control to maintain a constant environment inside our body, whether it's an environment of constant mass or constant composition, or constant temperature, is called homeostasis.
这个控制过程维持着,体内环境的恒定,不论是内环境中物质的量的稳定,或者成分的稳定,或温度的稳定,这种状态叫做内稳态

Depending on what you call external and internal environment, this path that I'm tracing here, deep within your digestive system, is really directly connected to the outside world through both ends.
基于你们所谓的外环境和内环境,我在这里我所指的消化系统内部通路,它的两端确实与外界环境直接相通

By determining how many of those molecules to hold onto, how many to keep in the body, how many to release determines the internal composition with regard to that ion.
通过控制体内这些分子的水平,即体内保有多少,又排出多少,就能够保证内环境中离子组成的稳定
