This normal weight animal like this has its whole equilibrium thrown off, its homeostasis thrown off when its dietary conditions change.
在饮食条件发生变化时,这些正常体重动物的生理平衡被打破,于是摈弃了原来的平衡饮食
-
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
-
Those foods that you see there, that throw off the animals homeostasis, and their hunger equilibrium are the same foods that are marketed very heavily.
你们看到的这些食物,打破了这些动物的内稳态和饥饿平衡,这些食品占据了大量市场份额
-
These are mechanisms that can be described not too differently from mechanisms that you're familiar with for maintaining homeostasis.
这些过程说起来,与你们熟悉的环境稳定机制,并无太大不同
-
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
-
Your body has elaborate mechanisms for maintaining this state of homeostasis, that is, things staying the same; the body stays the same, homeostasis.
你的身体有许多精妙的机制,来维持内稳态,也就是说体内物质不改变,身体状态不改变,这就是内稳态
-
So homeostasis is enabled by sometimes complex, sometimes very simple control mechanisms.
通过一些或复杂或简单的机制,使内稳态得以实现
-
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
-
The main function of all your cells, and all your tissues, and all your organs is to maintain this homeostasis, which allows you to live in a changing environment.
你所有细胞,所有的组织,所有的器官最主要的功能,就是维护这个内稳态,使你能够以不变应万变
-
How do those differences between cells contribute to the properties of the tissues, which contribute to the properties of the organs, which contribute to the properties of a person and this maintenance of homeostasis?
这些差异化的细胞,是如何构成具有不同属性的组织,这些组织又构成具有不同属性的器官,器官又构成了不同的人,它们是如何维护内稳态呢
