Your answer:
I predicted that as blood pressure increased so will the glomerular capillary pressure and filtration rate. The results proved my prediction because the more that blood enters the capillaries in the Bowman's capsule, the higher the pressure goes up, as well as the filtration rate increasing due to the high pressure. This always for more filtration of blood.
Compare the urine volume in your baseline data with the urine volume as you increased the
blood pressure. How did the urine volume change?
Your answer:
It can be seen that when blood pressure increases so does urine production increased. Thus showing that glomerular pressure, filtration rate, and urine volume will all increase because every time the glomerular pressure increased the filtration rate had to increase from the high pressure and lastly the high filtration rate causes an increase in urine volume.

How could the change in urine volume with the increase in blood pressure be viewed as
being beneficial to the body?
Your answer:
An increase in urine volume can be beneficial for the body because that means waste is getting filtered out of the body faster than it would normally. The more frequent urination causes a loss in water, resulting in a higher consumption of fluids to replace the fluid lost from urination. Which is also increases the urine volume, creating a beneficial cycle in filtering out waste at a fast rate from consuming fluids at an increasing rate to replace what was lost.

When the one-way valve between the collecting duct and the urinary bladder was closed,
what happened to the filtrate pressure in Bowman's capsule (this is not directly measured in
this experiment) and the glomerular filtration rate? How well did the results compare with
your prediction?
Your answer:
Whenever the valve was closed the filtration pressure remained the same, but the glomerular filtration rate decreased. I previously predicted that the pressure would increase and the filtration rate would decrease. The data shows that the glomerular pressure was the same compared to the rates with the valve open, showing that the pressure was not effected. However, the data did prove that the filtration rate decreased whenever the valve.

How did increasing the blood pressure alter the results when the valve was closed?
