Angiotensin receptor blockers (arbs) work in the body to lower blood pressure by which mechanism of action?

a. blocking at1 receptors, which prevent angiotensin from raising blood pressure
b. blocking the formation of renin in the raas system
c. blocking the conversion of angiotensin i to angiotensin ii
d. inhibiting the stimulation of aldosterone secretion

(The correct option is C) Blocking the conversion of angiotensin I to angiotensin II.

Explanation:

Angiotensin is known as a peptide. By the action of angiotensin converting enzyme (ACE) angiotensin I is transformed into angiotensin II in the blood.

Angiotensin receptor blockers help in the relaxation of arteries, and veins to lower the blood pressure, and making easy for the heart to pump blood. Drugs which helps to inhibit ACE, and block the conversion between angiotensin I, and angiotensin II are helping to lower the blood pressure in patience with hypertension.

d they all are treatable but they never completely go away
