How would pressure in the glomerulus be affected by constricting the afferent arteriole?
Pressure in the glumerulus would decrease. As a result, hydrostatic pressure would also decrease, resulting in a decreased filtration rate.
What is Pressure In Liquid?
The question is a bit vague, but two things come into play for pressure in a liquid: external pressure and hydrostatic pressure. For a liquid where the top surface is in contact with a gas, like a glass of water sitting out on the table, the external pressure would be the pressure of the gas. For the glass of water in this example, the pressure of the gas is just the ambient atmospheric pressure. In a pressure cooker with hot gas and hot liquid confined in a fixed volume, the pressure of the gas will probably reach the pressure the relief valve is set to. Hydrostatic pressure comes from the weight of the liquid above the liquid at any point in the liquid. As an example, if you go 10 meters down under the surface of the water in a swimming pool, you will feel the pressure created by the weight of the water above you. As a formula, P.H. (hydrostatic pressure) = (gravitational acceleration)x(density of liquid)x(depth of liquid). To get total pressure at any point in a liquid, you add the external pressure and the hydrostatic pressure. In situations like a hydraulic line, you would add the pressure exerted by the piston (external pressure) to the hydrostatic pressure from changes in the height of the hydraulic line. By the way, if the line goes UP, the effective depth is NEGATIVE and the hydrostatic pressure term is also negative, so you would have less pressure at the top of the hydraulic line than you did down at the level of the piston.

If the amount of chloride ion in blood plasma increases what would happen to hydrostatic pressure?
hypertension
What would cause a lump at the bottom of a fiberglass pool?
The most likely cause is hydrostatic pressure from underground water. This can be a very dangerous problem for the pool and I would contact the installer immediately for an onsite consultation. If it is hydrostatic pressure and is not relieved, the pool can be permanently damaged. thepoolandspawarehouse.com
Why would the pressure not rise in a plumbing system when you try to perform a hydrostatic test and what to do about it?
exspanion tank or relive valve
What is hydrostatic pressure used for drilling oil wells?
In Drilling terminology, hydrostatic pressure is "The pressure exerted on a column of fluid at rest". This said, an oil well is just a column of fluid. Hydrostatic pressure is used to control the formation pressure in a well in order to prevent a "kick" (an influx of fluid into the well bore) or a blow-out (an uncontrolled influx of fluid into the well bore). Hydrostatic Pressure is calculated by a simple calculation = depth in meters x weight of drilling fluid in kg/m3 x gravity constant of 0.00981. IE. drilling at a depth of 3459m with drilling fluid that weighs 1120 kg/m3 would give you a Hydrostatic pressure of 38005 kpa. This is the amount of pressure that is being exerted on the formation at 3459m
What clinical effects would high blood pressure have on the kidneys of a bedridden patient?
This patient would have a much lower glomerular hydrostatic pressure, and would therefore lose less fluids than normal.
Discuss the possible variations that would affect pressure if hot fluid is used in a pressure calibrator?
Discuss the possible variations that would affect pressure if hot fluid is used in a pressure calibrator?"
What would happen if the capsular hydrostatic pressure were increased above normal?
Net filtration would decrease. Source Mastering A and P book, chapter 25.
In the absence of any regulatory mechanisms what effect do you think an increase in blood pressure would have on glomerular filtration rate?
The rate of GFR will increase if the blood pressure increases, and will decrease if the plasma oncotic pressure increases. GFR=certain coefficient*arteriolar hydrotstatic pressure - (arteriolar oncotic pressure + glomerular hydrostatic pressure). Now, to put it very simply the arteriolar hydrostatic pressure is what the mean blood pressure in the afferent arteriole, so if it increases the GFR is bound to increase.
How would decreasing the amount of water in blood affect blood pressure?
Blood pressure would decrease
