When the one way valve between the collecting duct and the urinary bladder was closed, what happened to the filtrate pressure in Bowmans capsule and the glomerular filtration rate? If you close the one-way valve, pressure will increase in Bowmans capsule and filtration rate will decrease.
What will happen to the filtrate pressure in Bowman's capsule and filtration rate if you close?
Predict Question 2: What will happen to the filtrate pressure in Bowman's capsule (not directly measured in this experiment) and filtration rate if you close the one-way valve between the collecting duct and the urinary bladder? Your answer: Pressure will increase and filtration rate will decrease.
What happened to the filtration rate and urine output when the valve was closed?
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 . Urine output was zero.
What effect does closing the valve have on GFR urine output what condition's might this simulate?
The closing of the valve will decrease/eliminate GFR and urine output. This would simulate a tumor or renal calculi blocking a ureter .
What happens to glomerular filtration rate as the afferent Arteriole radius is increased?
Your answer: If we increase the efferent radius the capillary pressure and filtration rate will decrease . As the efferent radius is increased there is more time and less pressure for the blood to be filtrated hence is the change that both values decrease.
Which hormone has the greatest effect on urine volume?
Antidiuretic hormone (ADH) has the greatest effect on urine volume as compared to aldosterone.
What will happen to the glomerular capillary pressure and filtration rate if you decrease?
What will happen to the glomerular capillary pressure and filtration rate if you decrease the radius of the afferent arteriole? Both pressure and filtration rate will decrease . ... Both pressure and filtration rate will increase.
What is one factor that will have a significant impact on the glomerular filtration rate?
Both glomerular capillary hydrostatic pressure and renal blood flow are important determinants of the glomerular filtration rate (GFR).
What should not be found in filtrate?
Blood proteins and blood cells are too large to pass through the filtration membrane and should not be found in filtrate.
What Cannot pass through filtration membrane?
The substances that cannot pass through the filtration membrane of the kidneys are d. proteins .
What condition's might result if GFR is too low?
If GFR is too low, metabolic wastes will not get filtered from the blood into the renal tubules . If GFR is too high, the absorptive capacity of salt and water by the renal tubules becomes overwhelmed. Autoregulation manages these changes in GFR and RBF. There are two mechanisms by which this occurs.
What disease is characterized by a GFR 15ml min explain what is happening to filtration in this case?
Stage 5—GFR of 15 mL/min or less
Patients at Stage 5 have chronic CKD. They have a GFR of 15 mL/min or less and have End Stage Renal Disease (ESRD) . The kidneys have lost almost all ability to function effectively at this stage. They will need dialysis or a kidney transplant to live.
What condition is analogous to the valve above the collecting duct being shut off?
What common condition is analogous to the valve above the collecting duct being shut off? Kidney stones block the ureter connecting the kidney to the urinary bladder .
What happened to the glomerular filtration rate as the beaker pressure was increased?
Refer to Activity 2: Studying the Pressure on Glomerular Filtration. What happened to the glomerular filtration rate as the beaker pressure was increased? The glomerular filtration rate fluctuated as the collecting tubules became clogged . Glomerular filtration rate was not affected.
What is the normal range for the glomerular filtration rate?
in adults, the normal gFR number is more than 90 . For more information, see chart on the bottom of page 2. gFR declines with age, even in people without kidney disease. If your GFR is between 60 and 89...
What driving forces determine glomerular filtration rate?
The rate at which kidneys filter blood is called the glomerular filtration rate. The main driving force for the filtering process, or outward pressure is the blood pressure as it enters the glomerulus .
