Filtration results when substances are forced through capillary walls by osmotic pressure?

Filtration results when nutrients are moved through the capillary walls by hydrostatic pressure. Hydrostatic pressure in the capillaries is greater than the osmotic pressure so there is a net movement of fluid and/or solutes out of the capillaries.

What is the relation of the donnan effect to osmotic pressure on capillary and on pH?
the effect of Donnan effect to osmotic pressure on capillary is that it gives the capillary the ability to *some text missing*
What type of pressure causes to enter the venous side of the capillary?
Osmotic pressure...
How do net hydrostatic pressure and net osmotic pressure each change along the length of a capillary?
Net osmotic pressure stays about the same and net hydrostatic pressure decreases.
What is osmotic rate?
the change of osmotic pressure over time
What is the primary driving force that produces glomerular filtration?
Osmotic pressure in the blood vessel or cell pushes water from a place with a lower concentration of dissolved solids (there is more water on that side, proportionally), to the other side if there is a higher concentration of dissolved solids (because proportionally there is less water)
Which force favors blood filtration?
Capillary hydrostatic pressure and interstitial fluid osmotic pressure
Why water and dissolved substances leave the arterioles end of the capillary and enter the venule end?
Water and dissolved substances leave the arteriole end of the capillary due to hydrostatic pressure being higher than osmotic pressure and enter the venule of the capillary due to osmotic pressure being higher than hydrostatic pressure.
What is filtration pressure?
is the force responsible for moving fluid across capillary walls. It is the difference between net hydrostatic pressure and net osmotic pressure. NFP= Net hydrostatic pressure - net osmotic pressure
What is the normal net filtration pressure?
is the force responsible for moving fluid across capillary walls. It is the difference between net hydrostatic pressure and net osmotic pressure. NFP= Net hydrostatic pressure - net osmotic pressure
What is the relation of the donnan effect to osmotic pressure on capillary and on pH?
the effect of Donnan effect to osmotic pressure on capillary is that it gives the capillary the ability to *some text missing*
Which net pressure draws fluid into the capillary?
net osmotic pressure
When the osmotic pressure in a capillary exceeds the blood pressure in the capillary what is the net movement of fluid?
water and waste will move in capillary . water and waste will move in capillary .
What type of pressure causes to enter the venous side of the capillary?
Osmotic pressure...
What is Starling's Law of the capillaries?
The hypothesis that fluid filtration through capillary membranes is dependent on the balance between the pressure the blood places on the membranes and the osmotic pressure of the membranes. The law relating to the passage of fluid out of a capillary depending on the hydrostatic and osmotic pressures of the blood and the same pressures of tissue fluid, the net effect of the opposing pressures determining the direction and rate of flow.
What reflects balance between the direction and amount of fluid that flows across capillary walls?
Hydrostatic and osmotic pressure.
The most important force driving reabsorption at the venous end of a capillary is?
Blood colloid osmotic pressure
How do net hydrostatic pressure and net osmotic pressure each change along the length of a capillary?
Net osmotic pressure stays about the same and net hydrostatic pressure decreases.
