Question

Quizplus · Accepted Answer

The renin-angiotensin-aldosterone system (RAAS) is a pathway that regulates blood volume by controlling water and sodium retention. Blood volume is directly related to blood pressure, meaning that blood pressure increases when blood volume increases. The RAAS pathway is complex, involving many proteins and receptors, all of which are coded for by different genes. Problems in any one of them can lead to primary hypertension.
