First of all, the study of the structure of the body and the relationship between parts.
00:07
So the study, first one, of the structure of the body and the relationship between different parts, a way called anatomy.
00:41
So that's studying the structure of the body parts and the relationship.
00:45
Second, this is a study of the function and process of a living organism and their parts.
00:54
So it's again a study.
00:57
This is the study of function and the process.
01:06
That's the key word.
01:19
So this is what we call physiology.
01:31
So this is the definition of physiology.
01:32
Physiology.
01:33
The third, the maintenance of a stable, balanced internal environment within an organism.
01:43
So the key word here is the stable, balanced internal environment.
01:48
So the maintenance of a stable and balanced internal environment.
02:21
We call this process homeostasis.
02:30
For example, our body temperature is a homeostasis or the blood glucose level is a homeostasis because they all involve in the maintenance of a stable temperature, body temperature or stable blood glucose level.
02:45
The next concept or description is a mechanism that counteracts a change in the body and bring in condition back towards normal or optimal state.
03:25
So this basically we call it the negative feedback...
