|
|
The main drivers of solute movement between interstitial and plasma compartments
|
hydrostatic pressure and oncotic pressure
|
|
|
What is osmotic pressure
|
the pressure that must be applied to a solution to prevent the net flow of water into it
|
|
|
What is electrochemical gradient
|
is a separation made by oppositely charged ions by a membrane as generated by actively trabsporting one or more ions
|
|
|
What is hydrostatic pressure
|
pressure exerted by a fluid at equilibrium due to force of gravity, pumping of heart that eventually cause the fluid to leak out of capillaries
