Tubule

HOw can we identify the cell in PCT (proximal convolunted tubule) & decending limb of loop of henle ? Also ,, how can we identify the cell of PST(proximal straighted tubule) & PCT ???

... of antidiuretic hormone, as the name implies, serve to prevent water loss and dehydration, and therefore ADH will reabsorb sodium from the distal tubule, and water will follow by osmosis. Therefore, in the control of ADH, concentrated urine is produced, not dilute urine.

... but there is an active reabsorption of ions like Na+, K+ and Cl- meaning that the solution gets steadily more dilute towards the distal convoluted tubule. Important points here: medulla always has a high osmolarity. Vasa recta keeps salts often due to an active process rather than just diffusion.

I think I can help you. Even I had the same question. According to what I know collecting tubule leads to the collecting duct. And the collecting tubule is connected to the Distal convoluted tubule on the other end. That's how it is.

Hello I might be posting quite regularly as I am doing my revision for physiology :) I am just wondering about the collecting tubule, is it the same as collecting duct or is it somehow part of it, or could that relate to distal convoluted tubule? I would very much appreciate if anyone ...
