Glomeruli and Tubules of the Kidney accompanying Activity. 605 



The results of the experiment are again very decisive, a notable point 

 being the large volume of the glomeruli in both kidneys. We would again 

 point out that the main effect upon the convoluted tubules is seen in the 

 distal tubules.

The figures are in agreement with those of the preceding experiment, with 

 the exception that the volume of the glomeruli in this instance is small. In 

 Experiment 2 the blood-pressure was low (83 mm. Hg) and the diuresis 

 moderate, while in Experiment 5 the blood-pressure was high (130 mm. Hg) 

 and the flow of urine rapid.
