00:01 Let's discuss about this question which includes the loop of henley reabsorption.

00:13 Reabsorption mechanism.

00:15 So the first question which is asked here is that as the fultrate move out, move down to the loop of hennon, what will move across the wall of lefron? so the filterate moves down loop of henley.

00:46 Then what happened? the water moves across the walls of nephron.

01:02 Walls of nephrons.

01:08 Okay, so basically the water which is moving across the walls of nephron the water moves out so the water is moving out of nephron by passive process okay why what this is because the descending loop descending loop of henley is highly permeable to water.

02:04 At beginning of descending limb, its permeability is 300 mills permeable per litre.

02:28 Due to water permeability, the water moves out of the tube because of that water permeability where water is coming out of the tube that makes the permeability hypertonic.

02:56 And then it turns to be 1 ,200 millie osmo per liter in 1.

03:11 Osmolarity.

03:13 So what we have seen that the water is moving out, first thing, and it is moving out basically.

03:20 And by which process, by passive process.

03:24 So descending loop is more permeable for water.

03:27 So this type of change is happening.

03:29 That would be a hypotonic, hypertonic change in the osmolarity is happening.

03:34 Now let's talk about the next thing.

03:37 When we talk about the thinner segment, of that loop of henley, ascending arms.

03:47 So what will happen in that case, the filterate...
