adequate blood flow requires which 3 things?
|
Adequate pump
sufficiant blood volume efficient vascular/circulatory system |
|
|
permiablity--cell membranes become more permiable and fluid shifts occur. This is called
|
third spacing
|
|
|
if you have a problem with the pump the ____ are going to ____ to change the pressure
|
vessles, constrict or dialate
|
|
|
if you have a problem with loss of volume, the heart is going to ______ and the blood vessles are going to _____
