Fluid Shift Across Capillary Wall Flashcards
Which arterioles regulate regional blood flow to the Capillary Bed (CB) in most tissues?
terminal
What regulate flow in few tissues (e.g. mesentery)?
Precapillary Sphincters
Can plasma proteins cross the capillary wall?
No
Which Starling Forces favour filtration?
capillary hydrostatic pressure
interstitial fluid osmotic pressure
Which Starling Forces oppose filtration?
capillary osmotic pressure
interstitial fluid hydrostatic pressure
What do Starling Forces favour at ateriolar and venular ends?
Starling forces favour filtration at arteriolar end, reabsorption at venular end
What is oedema?
Accumulation of fluid in interstitial space
What are the 4 main general causes of oedema?
Raised capillary pressure
Reduced plasma osmotic pressure
Lymphatic insufficiency
Changes in capillary permeability
