Part 14: Net Filtration Pressure

Filtrate is produced due to what?

it is due to the pressure gradient across the filtration membrane

Substances move from ________ pressure to _______ pressure

high; low

The net filtration pressure is what type of pressure?

it is aggregate pressure

The net filtrate pressure is the aggregate pressure that causes fluid to move out of what?

it causes fluid to move out of a blood capillary

The net filtration pressure is calculated by what?

it is calculated by subtracting net osmotic pressure form net hydrostatic pressure

Net filtration pressure is effected by what three things?

\-glomerular hydrostatic pressure ((HPg)

\-blood colloid osmotic pressure (OPg)

\-capsular hydrostatic pressure (HPc)

Glomerular hydrostatic pressure (HPg) is the force that “pushes” water and solutes out of what?

it “pushes” water and solutes out of the glomerulus

Blood colloid osmotic pressure (OPg) is the force exerted by what?

it is the force exerted by the plasma protein

Blood colloid osmotic pressure (OPg) is the force exerted by plasma protein that “pulls” fluids back into what?

it “pulls” fluid back into the glomerulus

Capsular hydrostatic pressure (HPc) is the pressure exerted by the fluids where?

it is the pressure exerted by the fluids inside the capsular space

Capsular hydrostatic pressure (HPc) is the pressure exerted by the fluids inside the capsular space that resist movemnt of what?

it resist movement of additional fluids

What is the equation to finding out net filtration?

NFP = HPg - (OPg + HPc )

If Glomerular hydrostatic pressure (HPg) is 60 mmHg, Blood colloid osmotic pressure (OPg) is 32 mmHg, and Capsular hydrostatic pressure (HPc) is 18mmHg, what is the net filtration?

NF=10mmHg

* explanation:

NF=60-(32+18)
