Question

Is angiotensin II a vasoconstrictor?

Answer 1

Angiotensin II:

1. It is a very powerful vasoconstrictor which is involved in increasing the glomerular blood pressure, thus the glomerular filtration rate.
2. Renin-angiotensin system is a physiological hormone system which is involved in the regulation of arterial blood pressure as well as plasma sodium concentration.
3. The components of the renin-angiotensin system are:
   • Renin
   • Angiotensin I
   • Angiotensin II
   • Angiotensin-Converting Enzyme (ACE)
