Negative feedback loop wants to maintain homeostasis - it wants to always go back to the "status quo." Positive feedback loop wants to make a change - it wants something new to happen.

I would find it helpful if more was written out in this hormone series such as what happens to hormones in the liver, and the term "hypophyseal portal system" (had to google) from the last video, and so on.

Is it possible that the reason why the pituitary responds to the feedback loop is so that it can respond more quickly to a need for more Thyroid activity? If it kept going until the Hypothalamus finally got around to telling it to stop producing, it would be all cleared out of it's hormone, and have to wait for more signal from the thyroid to make it again. Am I understanding that correctly?

How does the body normally remove or breakdown hormones? Is there any specific place for specific hormone? like steroid hormones are broken down here, peptide hormones are broken down there.

TRH=throtropin releasing hormone. Not thyroid releasing hormone. But thanks :)

thyrotropin* not throtropin

@shiney94 4 года назад

@@epiphamas You idiot, I am not trying to mock her. There is a significant difference between thyrotrophin releasing hormone and thyroid releasing hormone. Thyrotrophin releasing hormone is produced from the hypothalamus whereas thyroid releasing hormone is released from the anterior pituitary gland. That is the only reason I showed it, not to be a jerk

@@shiney94 I'm sorry, I was correcting the spelling for the sake of clarity. I thought that was important. It would be nice not to be insulted.
