WebOct 13, 2016 · The renal system responds to hemorrhagic shock by stimulating an increase in renin secretion from the juxtaglomerular apparatus. Renin converts angiotensinogen to angiotensin I, which subsequently is converted to angiotensin II by the lungs and liver. Angiotensin II has 2 main effects, both of which help to reverse hemorrhagic shock ... WebSep 16, 2024 · This results in vasodilatation of the blood vessels, decrease in heart rate and myocardial contractility, and decrease in the rate of renin secretion by the juxtaglomerular apparatus. It is the integrity of the afferent and efferent mechanism in autoregulation that maintains the arterial blood pressure within a narrow range. Figure 3

WebAngiotensin III increases blood pressure and stimulates aldosterone secretion from the adrenal cortex; it has 100% adrenocortical stimulating activity and 40% vasopressor activity of angiotensin II. Angiotensin IV also has adrenocortical and vasopressor activities WebDec 21, 2024 · Angiotensin II stimulates an area in the brain called the "thirst center" to help increase blood pressure. This thirst center is located in a part of the brain called the hypothalamus. When the thirst center is told by angiotensin II that the blood pressure is too low, it creates a sensation of thirst.

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.
