Effect of negative venous pressure on the veins |
|
Definition
veins will collapse, causing flow of blood toward the heart |
|
|
Term
| Effect of increase in venous pressure/ venoconstriction on total peripheral resistance |
|
Definition
| there is very little change due to the fact venous R is comparatively low to that of arterioles |
|
|
Term
| Effect of increase in blood volume on vascular function curve |
|
Definition
increase venous return increase MSFP
|
|
|
Term
| Effect of increasing TPR on vascular function curve |
|
Definition
same MSFP decreased venous return

Term
| Effect of hypervolemia on equilibrium point |
|
Definition
increase CO increase venous pressure

Term
| Effect of cardiac sympathetic stimulation on equilibrium point |
|
Definition
As you increase HR, you deplete blood from venous circulation. |

|
Definition
Only that can restore venous pressure is restoring blood volume. |
