Term
|
Definition
Arteriole, Capillary, Venule
-Regulated by precapillary sphincter |
|
|
Term
|
Definition
-more room in the capillary than blood volume
-endothelial cells line the walls
-at any time only a small percentage are open |
|
|
Term
| Starling Forces of Hemodynamics |
|
Definition
-high pressure at arteriole end
-low pressure at venule end
-oncotic pressure similar to osmotic determined by proteins (albumin)
-hydrostatic pressure forces fluid outside of capillary (cell stay in)
-ontic pressure rises, sucks fluid back into capillary
-excess fluid is taken away by the lympathic vessels |
|
|
Term
|
Definition
-When we have to much fluid
-not enough oncotic pressure to suck the fluid back into the capillaries
-causes inflammation
increased venous hydrostatic pressure
-causes heart failure
reduced oncotic pressure |
