WebRenin secretion is under the control of a number of factors ( Kurtz, 2011). A fast rise in systemic blood pressure inhibits renin secretion via the direct effect of increased perfusion pressure on preglomerular vessels while circulating renin increases within minutes after a sharp fall in pressure. 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… feast day on jan 11 https://scanlannursery.com

WebThe primary stimulus for increased renin secretion is decreased blood flow to the kidneys, which may be caused by loss of sodium and water (as a result of diarrhea, persistent vomiting, or excessive perspiration) or by … WebRenin secretion was found to be controlled by a renal baroreceptor rather than by ischemia. Development of a sensitive assay technique that detects renin in small quantities of renal venous and peripheral arterial plasma has permitted the demonstration that the rate of renin secretion varies inversely with the level of arterial pressure independently of renal blood …

D. stimulation of the parasympathetic nervous system. E. decreased renin secretion. WebIt is concluded that lead may increase renin secretion in animals otherwise unstimulated to secrete but that the major mechanism for the short-term rise in PRA after lead is elimination of hepatic removal of renin; further, lead prevents All from rising proportionately with PRA, presumably by inhibiting angiotensin-converting enzyme.
