Question

ADH (Anti-diuretic hormone) is important in maintaining homeostasis in mammals. ADH is released from hypothalamus in response to high tissue osmolarity (=less water in blood). In response to ADH, the collecting duct and distal tubule in the kidney become more permeable to water, which increases water reabsorption into capillaries. The amount of hormone released is controlled by a negative feedback loop. Based on the model presented, what is the relationship between ADH release, osmolarity and production of urine? As tissue osmolarity rises, more ADH is released, causing less water to be excreted as urine As tissue osmolarity rises, less ADH is released, causing less water to be excreted as urine As tissue osmolarity rises, more ADH is released, causing more water to be excreted as urine As tissue osmolarity rises, less ADH is released, causing more water to be excreted as urine Two of the above

Step 1

ADH is released by the hypothalamus in response to high tissue osmolarity, which means there is less water relative to solutes in the blood. Show more…

00:01 Hello students.

00:02 Today's question is about we have to tell the relationship between the, we have to tell the relationship between the adhd release and osmolarity, osmolarity and urine.

00:16 So these are the different options.

00:17 Let's read one by one.

00:19 So first is as osmolarity rises, then a dh released and less water is excreted as urine.

00:28 As urine.

00:29 Next is as the osmolarity rises.

00:32 Adh will be less and also urine will be less.

00:35 Then more adh, more water.

00:38 Less adh, more water.

00:40 So the correct answer is this one.

00:43 Correct answer is the first one which indicates that as osmolarity rises.

00:51 As osmolarity rises.

00:56 So then more adh will be released.

00:59 More adh will be released and less water.

01:03 Will be excreted as urine.

01:07 Excreted as urine.

01:08 So why the relationship is like this? why the relationship is like this? so first of all, adh is a hormone which is antideuratic hormone.

01:20 Anti -duratic hormone that is a chemical produced in brain.

01:26 So this is going to be produced in brain.

01:28 But it causes the kidneys to release less water...
