Question

​​​​How were glomerular pressure, GFR, and urine volume affected when you closed the valve?

Answer 1

If you close the one way valve, pressure will increase in the Bowman's capsule and filtration rate will decrease. How did increasing the blood pressure alter the results when the valve was closed? With increased pressure and the valve closed, the filtration rate decreased but the glomerular pressure stayed the same.

If Valve is closed, the filtration rate decreased but the glomerular pressure stayed the same. Urine output was zero. When the solute concentration gradient in the interstitial space was increased, the urine volume decreased.
