13 Questions
Which of the following is true about the etiology of hypertension?
Patients with no specific cause of hypertension are said to have secondary hypertension.
What is the estimated heritability of essential hypertension?
30%
Which factors are believed to contribute to the development of hypertension?
All of the above
According to the hydraulic equation, arterial blood pressure (BP) is directly proportionate to the product of the blood flow (cardiac output, CO) and the resistance to passage of blood through precapillary arterioles (peripheral vascular resistance, PVR) + BP=COxPVR.
Hydraulic
Blood pressure is maintained by l Moment-to-moment regulation of cardiac output and peripheral vascular resistance exerted at three anatomic sites arterioles, ______, and heart.
postcapillary venules (capacitance vessels)
Kidney Baroreflexes mediated by autonomic nerves (combination with humoral mechanisms, including the ______)
renin-angiotensin-aldosterone system
Local release of ______
vasoactive substances
