Here in this video we will going to discuss that calcium regulation and negative feedback look of hormone with the help of a diagram also.
00:08
Right.
00:08
So here first of all we will explain that calcium in blood it is regulated by feedback mechanism.
00:19
Okay, it is simply regulated by the mechanism which we call as a feedback.
00:24
This means what if calcium level, okay? it goes up right then.
00:34
If it goes up and then it's inhibited.
00:38
When the level it increases, it's ultimately inhibited.
00:42
And when the level is low, like when there is a calcium level low, at that time, what happened there will be increase in the functioning.
00:51
So this is how a proper feedback mechanism work.
00:55
Now if i will give you a simple here explanation, if calcium level goes down, right, it will low down.
01:02
At that case, what happens, signals send to.
01:05
P -t -h that is parathyroid hormone, right? parathyroid hormone must be secreted at that time.
01:17
Right, so this hormone further it activate osteoclasts and by this activation would happen actually, this activation of the bone to secrete calcium okay, into the blood.
01:34
And in this way calcium level increases.
01:36
And here we can say as for the demand of the question, effect a cell is osteoclast...
