this increases SNS activity and stimulates vascular smooth muscle hypertrophy. Raises BP
|
|
|
How does obesity affect your BP?
|
this increases it due to release of angiotensiogen
added blood volume and increases blood viscosity |
|
|
What factors increase obesity-viseral-hypertension?
|
increases in leptin, aldosteron, RAS, insulin, FFA's

|
how does coarctation of the aorta affect BP?
|
this reduces blood flow to kidneys (and body)
promotes renin/angiotensin/aldosteron system |
|
|
what is pheochromcytoma?
|
this is catecholamine secreting tumor- increases CO and vasclar resistance
and this increases BP |
