If all other variables are kept constant, how does the afferent arteriole radius affect the rate of glomerular filtration select all that apply? Your answer : b.
How does each of them specifically alter the GFR? Renal mechanisms have effects on water excretion. GFR is large compared to the amount of urine produced. Most water in the filtrate because of renal processes and independent of ADH action Brandis, : 1. Glomerulotubular Balance- this is a local renal mechanism.
The proximal tubule is involved, and changes in oncotic pressure. Changes in hydrostatic pressure and delivery of certain solutes. When GFR increases protein concentration in efferent arteriole increases.
Along with increase in oncotic pressure in peritubular capillaries. Increased gradient for reabsorption and balances increasing GFR on volume of fluid exiting proximal tubule.
Auto-regulation of Blood flow- This affects water excretion, when renal perfusion pressure increases. The afferent arterioles vasco-constrict and renal plasma flow and GFR are constant. Urine flow is not auto-regulated. The rise in blood pressure will increase urine flow, and GFR is slightly affected.
Intrinsic Pressure- Volume Control System- This maintains constant blood volume- pressure diuresis and pressure natriuresis. The kidneys regulate excreting water and sodium into urine, to regulate blood volume Klabunde, : 1.
Activation of renin-angiotensin-aldosterne system increases sodium retention and reduces water loss into urine. This occurs in renal artery stenosis and can cause secondary hypertension.
Use of ADH antidiuretic hormone which is released by posterior pituitary. This simulates water reabsorption in collection duct, and decreases water loss and increases blood volume. Blood volume affects arterial pressure and change cardiac output.
Increase in blood volume increases central venous pressure. This causes increase in the right atrial, right ventricular and volume. Wow, this is a complete answer! Describe and explain what happened to the glomerular capillary pressure and GFR when both arteriole radii changes were implemented simultaneously with the low blood pressure condition.
The simultaneously implementation of both arteriole rates changing caused glomerular filtration rate and low blood pressure conditions went above the baseline value.Aldosterone is produced in the 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.
