Antidiuretic hormone (ADH) a. increases water reabsorption in the kidneys. b. regulates blood pressure by constricting arterioles. c. decreases the volume of urine produced by the kidneys. d. probably arose from the same ancestral gene as that of oxytocin. e. does all of the above.

Hi, so this video is going to go over a problem six in chapter 50 of Biology textbook. Um and chapter 50 is going over endocrine system. So um and this question is we're just trying to define what does a th do And this question is a multiple choice question but I'm going to go through all the choices and Um hopefully it'll answer which one is correct. All right. So just a quick overview of 80 h. so 80 h is released from the post interior pituitary and the pituitary gland is in close relation with the hypothalamus. You have your anterior pituitary in your posterior pituitary, your into your pituitary is going to release the hormones. Um And it's going to be stimulated by hormones that are released by the hypothalamus. And those hormones are going to travel through the portal veins through the infant tubular stock and then um interact with the anterior pituitary cells. Anti apartheid sl pituitary cells release hormones. Um A lot of the interior pituitary hormones are like FSH, LH um TSH and I would recommend going over of the anterior pituitary or another video about the anterior pituitary. If you have further questions about those. Um The post your pituitary is actually kind of interesting because we have neurons in the hypothalamus that travel down their accents, traveled down through the infant tubular stock. And in the post here pituitary, they synapse and they release hormones onto blood vessels. So these hormones are very special in the fact that they are created and released by nerve cells onto a blood vessel instead of glandular cells. Um and it releases two hormones A th and oxytocin 88. You're anti diuretic hormone and sometimes called vasopressin. Um this is an important in water regulation. Um So in short, what it's going to do is a th is going to go to the kidneys and it's going to act on the kidneys and overall you want to decrease our urine output. So if um we are dehydrated, we're not drinking enough water. Maybe our blood pressure's kind of low. We want to reserve that fluid. Um, then we will decrease, released a th which will decrease our urine output. But how does that work? So what happens is we have our um we have these little things in our kidneys called net franz and they are responsible for filtering out all sorts of ions and wastes and keeping nutrients and um and then it's important in water regulation. So when we drink a lot of water, it releases water so that we can pee it out. But when we don't have enough water, we're going to keep the water. So what how that happens is we're going to increase water re absorption. And all that means is that any of the water that gets through this Neff Ron and is headed to be released through urine before it gets released. It's going to be reabsorbed back into our blood. And so we keep that water and we don't pay it out as much. So um that's how the that's how the kidneys decreased urine output. Yeah. Another way that the kidneys um regulate our water balance is we're going to constrict blood vessels to increase our blood pressure or regulate our broad pressure. Um And in specific arterials are usually the ones that are regulated by this. So it's going to constrict them and tighten them so that we can regulate your blood pressure. Um And then another way that it helps. So if you have blood loss, so like let's say you cut your arm open your bleeding, you lost a lot of blood. What? This is pretty bad because you you could bleed out. You can lose your blood, you can lose enough fluid to where you don't have enough blood pressure to keep your blood moving. And so with blood loss we're going to release a th and This 88 is going to decrease their urine output by increasing our water reabsorption. So that's going to increase our blood pressure. Because anytime we keep water in our blood vessels there's this there's an increase in blood pressure there. So if we lose water we're going to decrease our blood pressure. Keep water in our blood vessels were going to increase our blood pressure. Um And then another way that that that it does this is constricting blood vessels to increase their blood pressure. Um And so this overall 80 H. Acts on decreasing urine output, keeping water in our system. Um Keeping our blood pressure up when we don't want it to draw, and then also regulating by regulating blood pressure, by constricting the blood vessels. So for the answer for this question, it would be all of the above because it does all of these things, and that's probably why it's released by the post your pituitary because it's so so so important in regulating just, I mean, in emergency situations like blood possible, also just on a day to day basis, regulating our water balance.

So the question here basically asked what is the function of 80 h otherwise known as anti diuretic? So we know that 80 here, um, places more acorns, you know, to increase the water absorption. So as a result of this, you're going to excrete less water from your body. So the question answer is going to be

Alright, Problem number five. So let's talk about Neff Ron Net Franz, remember is what helps the body absorb nutrients and water or re absorb it and before it goes, be turned into urine. But Met Franz don't do the exact same thing every time. Nef Franz are actually controlled controlled by hormone and this is the case with a lot of things in our body. So if the body senses that you're dehydrated than it might release a hormone that would affect the kidneys or might not release a hormone if you're not dehydrated and stuff like that Sonett Franz actually controlled by hormones which are released from the brain. And so this question asked, what happens when a specific hormone off a th what happens when this is introduced or will say when this is present? So what happens to net Franz when 88 is president? So I think the easiest way to answer this scroll down here and put two pictures up one of when a th is present and another of when there is no a th president. So we're just gonna split the screen down the middle and on the left, we will do a th so a you a And over here No, e a We're gonna try to draw the same structure on each side. But I might not be that good at drawing, so bear with me. But remember, we have a collecting apparatus here called the renal or coalfield or a crucial however you want to pronounce that that starts here, come down, uh, a way around and then out. And then we got to connect this real quick. All right, so that's what we're looking at right now. Remember, we're also inside an entire structure on the inside of a kidney. Okay? And we'll try Draw that same structure over here, down around to get wider here, and we'll talk about why it gets wider there. And then out we got connected. And again, we're part of this entire. So we were in the cortex up at the top on the Maduro as we get deeper inside. So normally in red, both of these pictures, with or without 88 you always have I on Saul use all right side of these two. They actually come all the way down and around. And this is actually where the similarities with Saul, you'd end, and we'll talk about why here second, but on both sides water is removed as we're moving down. So water is removed as we're moving down this arm, and this happens every time. Okay, then, as we are going up the arm on the other side, we actually start to lose. Saw you they read. And so they leave here at the bottom passively. They don't need any energy. But up here at the CAA, the circle is on both sides. They leave, but it's ac this so it's active transport. The cells are pushing it out of here at the top. Okay, so this happens on both sides, no matter what, where the difference occurred is that when you have a T h right here on the left, when you have a d h, it adds these little proteins here to decide these proteins are called aqua Poor mark work, Warren. That's all. One word aqua porn's. And these are proteins that let water get through. Water is huge, and it couldn't get through normal membranes that needs special protein. So when a th is present, it adds, these aqua porn's here on the left so water can leave even more The water starts to leave here even more and it leaves a very very side open Very soul eyes All that water has been removed Which leaves us with concentrated urine concentrated You're so it would look very yellow on the right side These are Quilp Oren's are not added to the sides here and instead it is not very salty on the inside And you have a large volume of your large for all you uh you're so that's what happens with no a th so in conclusion in conclusion 88 please two concentrated urine because the body the body re absorbs water No t know a th believed Teoh high volume dilute your because the body does not re absorb water. So in other words, the body releases a th when it's e hydrate a and is the least when you are dehydrate

Answer for the question here in discussion. Parsi istea Correct option. It increases water permeability off the collecting that.
