L7 physiology Flashcards
principle force in capillary filtration
-blood pressure within the capillary
hydrostatic pressure
key factor that restrains fluid loss from the capillary
- albumin predominates in determining this pressure
Oncotic pressure (celloid osmotic pressure)
forces _____ filtration:
1- capillary hydrostatic pressure
2- interstitial fluid oncotic pressure (colloid osmotic pressure)
With
forces _____ filtration:
1- interstitial fluid hydrostatic pressure
2- capillary plasma oncotic pressure (colloid osmotic pressure)
Against
accumulation of fluid within the interstitial spaces
-causes:
A) increased capillary hydrostatic pressure (more filtration) (high interstitial fluid) LEADS to kidney, heart failure
B)lowered plasma osmotic pressure (less force) (fluid will filter out) LEADS to burns, liver diseases(cirrhosis), nephrotic syndrome
EDEMA
A/G ratio:
the underproduction of ______, such as seen multiple myeloma
Albumin
