Document Summary
Physl 214 - lecture #11 - water reabsorption medullary osmotic gradient (countercurrent multiplier: water input/day = water output/day, reabsorbed water, the kidney can generate a urine. Concentrated as 1200 mosm: dilute urine, well hydrates, water, solute, water, solute, dehydrated, concentrated urine, kidneys have to produce 600 mosmol/day. Impermeable to h2: no active solute reabsorption (stays high, becomes dilute by the end of the loop of henle, either remains dilute or becomes concentrated by the end of the collecting duct, a closer look at. Reabsorption: how to create an osmotic gradient, h2o wants to flow to the osmolarity, this is done in. Osmotic gradient is established and the limit is reached: the 1200-1400 mosm in the inner medulla, half of it is caused by salt and the other half, urea, how do desert animals survive with such. Little amounts of water: they absorb all the water they can, 1. To water: late distal tubule and collecting.
