Net filtration pressure |
Is equal to the combined pressures of the blood in the capillaries minus the combined pressures of the tissues interstitial fluid |
|
Permeability edema |
Caused by capillaries being leaky to some protein |
|
Blood hydrostatic pressure pushes fluid..... Blood colloid osmotic pressure pushes fluid.... At the arterial end |
Out In |
|
The main force that causes fluid to enter the Venous end |
Colloid osmotic pressure |
|
NOP net osmotic |
Difference in osmotic pressure between blood and interstitial fluid |
|
IFP |
Generated by interstitial fluid found in tissue spaces |
|
When net hydrostatic pressure less than net osmotic pressure |
Venous end |
|
When is net hydrostatic pressure greater than net osmotic pressure |
Arterial end |
|
When the next filtration pressure negative fluid moves |
Into the capillary |
|
When the net filtration pressure is positive the fluid moves |
Out of the capillary |
|
Which pressure is the difference between blood and interstitial fluid |
NHP net hydrostatic |
|
Which allow the outward movement of food from the capillary |
- the NHP if greater than NOP -the net filtration pressure is positive |
|
What would happen to the outward Movement of food in capillaries if blood pressure decreases |
Decrease of movement |
|
Weekday would happen if there was a decrease concentration of albumin |
Edema |
|
Why is IFP expressed as a negative number |
The suction effect of the lymphatic vessels |
|
How is local control of blood flow achieved |
Periodic relaxation and contraction of precapillary sphincters |
|
Hydrostatic pressure is.... And colloid osmotic pressure is..... At the arterial end of the capillary |
Higher Lower |
|
Net hydrostatic pressure NHP |
BP+IFP |
|
Net osmotic pressure NOP |
BCOP-ICOP Solutes, power they have to pull water from a higher concentration to lower concentration to reach equilibrium |
|
Net filtration pressure NFP |
NHP-NOP
|
|
Which drives pressure out? |
BP, Interstitial colloid osmotic pressure, Interstitial fluid pressure |
|
Which drives in |
Blood colloid osmotic pressure Solutes or protein inside capillary |
|
What is the role of albumin |
Larger protein that cannot leave capillary. Keeping the number of solutes higher so water wants to move into capillary |
|
Net filtration pressure is |
All the fluid going out minus the fluid going in. More going out at the arterial end then the Venous end. The lymohatic system drains away the 10 percent extra fluid that is not reabsorbed |
|
Hydrostatic edema |
Increased pressure in capillaries more food goes into interstitial space |
|
Permeability edema |
Allow more solutes out Water follows molecules out |
|
Lymph edema |
Reduced drainage Lymph is damaged |
|
Osmotic edema |
Reduction of plasma protein in the capillary or more protein out of capillary. |
