What would happen to filtrate osmolarity if the descending limb was NOT permeable to water?

List specific transport mechanisms occurring in different parts of the nephron, including active transport, osmosis, facilitated diffusion.

An animal like salmon that can survive large fluctuations in external osmolarity is called (?????).

If plasma osmolarity increases to 380 mOsM, what would likely happen to the plasma concentrations of ADH and the reabsorption of water from the kidneys?   a. Plasma ADH concentrations decrease; reabsorption of water decreases b. Plasma ADH concentrations increase; reabsorption of water decreases c. Plasma ADH concentrations increase; reabsorption of water does not change d. Plasma ADH concentrations increase; reabsorption of water increases e. Plasma ADH concentrations decrease; reabsorption of water increases

What would happen to filtrate osmolarity if NaCl was NOT reabsorbed in the ascending limb??

Describe osmolarity in the urinary system  and provide examples.
