Your answer: c. How does each of them specifically alter the GFR. If all other variables are kept constant, how does the efferent arteriole radius affect the rate of glomerular filtration select all that apply.
The kidneys regulate excreting water and sodium into urine, to regulate blood volume Klabunde, : 1. In the absence of other renal processes including tubular reabsorption and secretionmore glomerular filtration leads to a larger urine volume.
Auto-regulation of Blood flow- This affects water excretion, when renal perfusion pressure increases. Along with increase in oncotic pressure in peritubular capillaries.
How could you adjust the afferent or efferent radius to compensate for the effect of reduced blood pressure on the glomerular filtration rate. A decreased efferent arteriole radius will decrease the rate of glomerular filtration.
We will write a custom essay sample on Renal System Physiology Physioex or any similar topic only for you Order Now A decreased afferent arteriole radius will decrease the rate of glomerular filtration.
The afferent arteriole dilation improved the low glomerular capillary pressure and filtration rate marginally. GFR is large compared to the amount of urine produced. You correctly answered: a. Your answer : c. All of the above are correct.
With blood pressure held at a constant value, which of the following combinations will raise the glomerular filtration rate above baseline values. Use of ADH antidiuretic hormone which is released by posterior pituitary.
Most water in the filtrate because of renal processes and independent of ADH action Brandis, : 1.
How well did the results compare with your prediction. Correct answer: b. Your answer: Renal mechanisms have effects on water excretion. This occurs in renal artery stenosis and can cause secondary hypertension. This simulates water reabsorption in collection duct, and decreases water loss and increases blood volume.
An increased afferent arteriole radius will increase the rate of glomerular filtration. Your answer: You can co nstrict or dilate them. Your answer: There was a greater increase of glomerular pressure when afferent radius is increased rather than the decrease of the efferent radius.
Intrinsic Pressure- Volume Control System- This maintains constant blood volume- pressure diuresis and pressure natriuresis. The simultaneously implementation of both arteriole rates changing caused glomerular filtration rate and low blood pressure conditions went above the baseline value.
When GFR increases protein concentration in efferent arteriole increases. The proximal tubule is involved, and changes in oncotic pressure.
In the body, how does a nephron maintain a near-constant glomerular filtration rate despite a constantly fluctuating blood pressure.
A decreased efferent arteriole radius will increase the rate of glomerular filtration. Aldosterone is produced in the You correctly answered: c.
adrenal cortex. 4. ADH promotes the renal reabsorption of You correctly answered: a. water. 5. Aldosterone promotes renal reabsorption of __________ and secretion of __________. You correctly answered: c.

As blood pressure increased, what happened to the glomerular capillary pressure and the glomerular filtration rate? How.
Pre-lab Quiz Results. If blood pressure goes down, the rate of glomerular filtration goes up. Correct answer: b. If blood pressure goes up, the rate of glomerular filtration goes up. d. If blood pressure goes down, the rate of glomerular filtration goes down.
4. In the absence of other renal processes (including tubular reabsorption and secretion). PhysioEx 9: Renal System Physiology. water and solutes that the body still needs are transferred into the plasma from the lumen of the tubules for transport back into systemic circulation via the peritubular capillaries which dump into the renal vein.
