What is the osmotic pressure difference that exists from the top of the cortex to the bottom of the medulla in the human kidney? Give an answer in both atmospheres and mm Hg.
The difference in pressure between cortex and medulla is 17370 mmHg calculated using the net osmolarity difference of 300-1200 = 900 mOsmol x 19.3 = 17330 mmHg
Now, to convert it into atm simply divide the mmHg value by 760 as 17370 / 760 = 22.85 atm
