gfr is the net results of the balance between hydrostatic pressures &colloid osmotic pressures of intra vascular compartment & within the Bowman's capsule,where the net pressure gradient is towards filtration.i.e. "Net filtration pressure".Any method which will reduce this net filtration pressure will reduce GFR.That can be achieved by increasing the plasma globulin ad albumin level(increase colloid osmotic pressure),hypotension and addition of vasocostrictor at afferent and vasodialtors at efferent tubule(reducing capilary hydrostatic pressure) or obstructing the free flow of urine(increasing Bowman's casular hydrostatic pressure)
What else can I help you with?
How does glomerular hydrostatic pressure effect filtration rate?
Glomerular hydrostatic pressure is the primary driving force for filtration rate in the kidneys. An increase in glomerular hydrostatic pressure will increase the rate of filtration by pushing more fluid and solutes out of the blood and into the renal tubules. Conversely, a decrease in glomerular hydrostatic pressure will decrease the filtration rate.
Does dilation of the afferent arteriole decrease Glomular filtration rate?
No, dilation of the afferent arteriole typically increases glomerular filtration rate by allowing more blood flow into the glomerulus. Constriction of the afferent arteriole would decrease the glomerular filtration rate.
What is the effect of constricted arterioles in the glomerular filtration rate?
Constricted arterioles in the glomerulus can lead to a decrease in the glomerular filtration rate (GFR) by reducing the amount of blood flow entering the glomerulus. This can result in decreased filtration of waste and reduced urine production.
What is the normal adult glomerular filtration rate?
Glomerular filtration rate is the rate at which fluid is filtered by the kidneys. The normal rate for humans is 125mL/min or 180L/day. The fluid that is filtered (and not reabsorbed later) is excreted as urine.
How would pressure in the glomerulus be affected by constricting the afferent arteriole?
Constricting the afferent arteriole would decrease blood flow into the glomerulus, leading to a decrease in pressure within the glomerulus. This may result in a decrease in glomerular filtration rate and a reduction in the formation of urine.

An increase in glomerular hydrostatic pressure will increase the rate of filtration by pushing more fluid and solutes out of the blood and into the renal tubules.

No, dilation of the afferent arteriole typically increases glomerular filtration rate by allowing more blood flow into the glomerulus. Constriction of the afferent arteriole would decrease the glomerular filtration rate.
Macula densa feedback (tubuloglomerular feedback) decrease or increase?
The macula densa is involved in tubuloglomerular feedback to help regulate glomerular filtration rate. An increase in NaCl concentration at the macula densa leads to vasoconstriction of the afferent arteriole, decreasing glomerular filtration rate. Conversely, a decrease in NaCl concentration leads to vasodilation of the afferent arteriole, increasing glomerular filtration rate.
What is the effect of constricted arterioles in the glomerular filtration rate?
Constricted arterioles in the glomerulus can lead to a decrease in the glomerular filtration rate (GFR) by reducing the amount of blood flow entering the glomerulus. This can result in decreased filtration of waste and reduced urine production.
Is the kidney functional when the glomerular filtration rate is zero?
no
What is injected to measure glomerular filtration rate?
inulin
What does the medical abbreviation GFR mean?
Glomerular Filtration RateThe GFR stands for glomerular filtration rate, and assesses kidney function.
What does the medical abbreivation GRF mean'?
Glomerular filtration rate

Filtration at the glomerulus is directly related what.?
Filtration at the glomerulus is directly related to the hydrostatic pressure in the glomerular capillaries, the oncotic pressure in the Bowman's capsule, and the glomerular filtration rate (GFR). These factors influence the movement of fluid and solutes across the glomerular filtration barrier.
Define glomerular filtration rate Name and describe the pressures which are effective at the glomerulus under normal conditions and result in glomerular filtration?
Glomerular filtration is a passive process in which hydrostatic pressure forces fluids and solutes through a membraneThe glomerular filtration rate (GFR) is directly proportional to the net filtration pressure and is about 125 ml/min (180 L/day).The glomeruli function as filters. High glomerular blood pressure (55 mm Hg) occurs because the glomeruli are fed and drained by arterioles, and the afferent arterioles are larger in diameter than the efferent arterioles.
