Renin mediates extracellular volume (i.e., that of the blood plasma, lymph and interstitial fluid), and arterial vasoconstriction. Thus, it regulates the body's mean arterial blood pressure.
It activates the renin-angiotensin system by cleaving angiotensinogen, produced by the liver, to yield angiotensin I, which is further converted into angiotensin II by ACE.
Angiotensin II then constricts blood vessels, increases the secretion of ADH and aldosterone, and stimulates the hypothalamus to activate the thirst reflex, each leading to an increase in blood pressure.

What enzyme is released by the juxtaglomerular cells?
renin
Where is renin synthesized?
Renin is synthesized in the juxtaglomerular cells of the Kidney. Renin acts on the liver to synthesize Angiotensin I
What substance performs the function of renin to the adults?
Renin.
The enzyme renin raises blood pressure by activating the?
renin activates angiotensin in the blood
Why would someone need to use renin?
Renin is a protein released by cells in your kidneys when you have low sodium levels. Renin increases the amount of angiotensinogenase increasing blood pressure and renin inhibitors are used to prevent increased blood pressure that can lead to a number of problems.
What is a renin stimulation test?
The renin stimulation test is performed to help diagnose and distinguish the two forms of hyperaldosteronism.
What results if the kidney produces too much renin?
Hypertension (high blood pressure) occurs in cases of excess renin.
Is renin a hormone?
by function is enzyme ... by structure is hormone
Which hormones is secreated by kidney?
renin
The enzyme produced by the kidneys when blood pressure drops stimulating a release of aldosterone?
Heart & brain functions effects blood pressure.
What is the purpose of plasma renin activity?
Plasma renin activity (PRA), also called plasma renin assay, may be used to screen for high blood pressure (hypertension ) of kidney origin, and may help plan treatment of essential hypertension
Does Renin cause a decrease in blood pressure?
No. Renin causes the blood pressure to rise. By low blood pressure the body releases Renin from the kidneys. Renin cleaves an inactive peptide, called Angiotensinogen, converting it to Angiotensin I. Angiotensin I is then converted to Angiotensin II by ACE (Angiotensin-Converting-Enzyme). Angiotensin II causes vasoconstriction and thus an increase in blood pressure.
