Blood pressure [r]: Pressure of the blood on the arteries and other blood vessels. ^[e]

Renin [r]: A highly specific (Leu-Leu) endopeptidase that generates angiotensin I from its precursor angiotensinogen, leading to a cascade of reactions which elevate blood pressure and increase sodium retention by the kidney in the renin-angiotensin system. ^[e]
Angiotensin [r]: Oligopeptides which are important in the regulation of blood pressure (vasoconstriction) and fluid homeostasis via the renin-angiotensin system. These include angiotensins derived naturally from precursor angiotensinogen, and those synthesized. ^[e]
Angiotensin receptor [r]: Cell surface proteins that bind angiotensins and trigger intracellular changes influencing the behavior of cells. ^[e]

Angiotensin II receptor antagonist [r]: Agents that antagonize angiotensin II type 1 receptor. Included are angiotensin II analogs such as saralasin and biphenylimidazoles such as losartan. Some are used as antihypertensive agents. ^[e]
Angiotensin-converting enzyme inhibitor [r]: Drugs mainly used to treat hypertension and heart failure, by hemodynamic effect inhibiting the renin-angiotensin system. ^[e]
Blood pressure [r]: Pressure of the blood on the arteries and other blood vessels. ^[e]
Hypertension [r]: A multisystem disease whose hallmark is the elevation of blood pressure. ^[e]
