WebThe renin-angiotensin-aldosterone system (RAAS) attempts to maintain arterial blood pressure by controlling blood volume. a decrease in arterial blood pressure is sensed by the kidneys as decreased renal perfusion pressure. note that increased sympathetic activity and β1-agonists (e.g., isoproterenol) increase renin secretion. Renin activates the renin–angiotensin system by using its endopeptidase activity to cleave the peptide bonds between leucine and valine residues in angiotensinogen, produced by the liver, to yield angiotensin I, which is further converted into angiotensin II by ACE, the angiotensin–converting enzyme primarily within the capillaries of the lungs. Angiotensin II then constricts blood vessels, increases the secretion of ADH and aldosterone, and stimulates the hypothalamus to activate the t… focus countdown https://crofootgroup.com
