      Angiotensin II (Ang II), an octapeptide hormone, is the active component of the renin–angiotensin system (RAS). Ang II is produced systemically via the “renal” RAS, and locally via “tissue” RAS. It contributes to the regulation of blood pressure, plasma volume via aldosterone-regulated sodium excretion, sympathetic nervous activity,
