Flashcards in PSL301: Cardio 8 Deck (44)
capillary hydrostatic pressure
interstitial fluid pressure
plasma colloid osmotic pressure
Interstitial fluid colloid pressure
move fluid out
due to fluid pressure in blood
move fluid in
Opposes outward movement of Pc
due to fluid pressure in ISF
Move fluid in
if proteins in blood > proteins in ISF
Move fluid out
if proteins in ISF > proteins in blood
Formula: net fluid pressure (at capillaries)
Fluid out - fluid in
[Pc + (pi)if] - [Pif + (pi)c]
- 3 mmHg
Lymphatic system remove fluid
45 to 10 mmHg
Lympathic system remove proteins
Value: plasma protein concentration
What makes up the plasma proteins?
Very little fibrinogen
Value: interstitial protein concentration
If net fluid pressure is positive...
More fluid going out of vessel
If net fluid pressure is negative...
More fluid going into vessel
Due to the gradient from Pc, __L of net flow outward per day
Forces that push fluid out of vessels
1. Hydrostatic pressure
2. Pressure from LACK OF fluid in ISF
3. Interstitial colloid osmotic pressure
Forces that push fluid into vessels
1. plasma colloid osmotic pressure
Value: mean hydrostatic pressure
Value: filtration coefficient
Formula: filtration rate
filtration coefficient * net filtration pressure
Value: net filtration rate
that much fluid is deposited in ISF every minute
Functions of lympathic system
1. Return fluid & proteins to circulatory system
2. Pick up fat from intestines and deliver to circulatory system
3. Help trap pathogens
Lymphatic system help prevent...
Lymph is derived from...
Where does the lymphatic system drain into?
