Angiotensin Ii Causes Vasoconstriction of Which of the Following

Valsartan is a prodrug that produces direct antagonism of angiotensin II receptors. Renin converts angiotensinogen into angiotensin I which is converted into angiotensin II with the aid of angiotensin-converting enzyme ACE.

Vasopressin works specifically on the arterioles smaller arteries.

. It displaces angiotensin II from AT1 receptors and may lower blood pressure by antagonizing AT1-induced vasoconstriction aldosterone release catecholamine release arginine vasopressin release water intake and hypertrophic responses. These include activation of sympathetic nerves and the renin-angiotensin system and increased release of antidiuretic hormone vasopressin and atrial natriuretic peptideThe net effect of these neurohumoral responses is to produce arterial vasoconstriction to help maintain arterial pressure venous constriction to. Angiotensin II increases production of the hormone vasopressin antidiuretic hormone and also stimulates vasoconstriction receptors.

The binding of the severe acute respiratory syndrome coronavirus 2 SARS-CoV-2 spike glycoprotein to its cellular receptor the angiotensin-converting enzyme 2 ACE2 causes its downregulation which subsequently leads to the dysregulation of the reninangiotensin system RAS in favor of the ACEangiotensin II Ang IIangiotensin II type I receptor AT1R. Neurohumoral responses occur during heart failure.
