So for this question, we need to talk about what plays into the half -life or why could a hormone have a long half -life? so there's a few things we need to understand, first of all.
00:17
So let's talk about what half -life means.
00:20
And half -life is just a measurement of something that is decreasing in concentration.
00:25
So half -life just means the amount of time we can decrease the concentration by 50 % so essentially, how long can we go from one to one half and then one half to one fourth? and it's a set amount of time for it to decrease in value by half of its original value.
00:45
And we're going to talk about is certain hormones that are circulating.
00:50
And we're talking about circulating.
00:51
We should be thinking about the circulatory system.
00:54
And it's very interesting to think about where our words come from.
00:59
Because we talk about circulation or circulating in the body.
01:03
We're talking about the circulatory system.
01:04
The circulatory system is, of course, going to be in reference to blood, our vessels, and our heart.
01:15
So when we're talking about circulating, we're talking about the circulatory system, specifically blood and the vessels that we could find different things in.
01:23
And hormones do circulate throughout our bloodstream.
01:26
So these are important things to think about.
01:28
So where does our blood go? where does our blood go? so first of all, our blood goes to the liver.
01:38
Which is a very notable organ, which if you think about, if someone has too many drinks, the liver is getting abused because the liver's job, the liver's job, is to break things down, right? things that don't need to be in the blood anymore.
01:53
And alcohol is liver toxic, right? and then our liver is overtaxed with trying to break down its alcohol and to detoxify your blood.
02:01
But enough about alcohol, we're talking about hormones.
02:04
Because if we have too much hormone, or we don't need that hormone in our blood anymore, our liver will degrade the hormone and trying to break it down.
02:18
And then when we're trying to get rid of these hormones, if it's broken down in our blood, the blood also goes to our kidneys because our kidneys filter out things from our blood that we don't need that are waste products.
02:30
And then along with water and things like that, it is excreted out via urine.
02:36
It goes to our urators and then goes out to whatever, land you may or may not have depending on your gender to urinate out.
02:47
That's why you can look at urine samples and it'll tell you a lot about different tests that you might want to do to find different hormones or anything in your blood.
02:55
For example, if you want to see if someone has excessive amounts of testosterone, they might be urinating somewhat out...
