Taking anti-HTN meds
What is normal BP?
Less than 120/80
What is prehypertension?

Primary/essential HTN versus secondary HTN?
Primary: idiopathic(don’t know cause)- many lifestyle factors
Tx = managed by lifestyle/meds
Secondary: caused by medical condition.
It is reversible with Tx
What pathway and specific enzyme is main regulator of BP (long term) ?

What pathway and factors are a short term change in BP?
(MAP) mean arterial blood pressure changed by stroke volume and heart rate.
