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 else can I help you with?
What stimulates the renin-angiotensin system?
Stimuli such as low blood pressure, low blood volume, and low sodium levels in the blood can activate the renin-angiotensin system. These triggers result in the release of renin, an enzyme that starts the cascade leading to the production of angiotensin II, a powerful vasoconstrictor.
What enzyme is released by the juxtaglomerular cells?
Renin is the enzyme released by juxtaglomerular cells. It plays a key role in the renin-angiotensin-aldosterone system, which helps regulate blood pressure and fluid balance in the body.
What substance performs the function of renin to the adults?
Renin.
Is renin a hormone or enzyme?
Renin is an enzyme, not a hormone.
The enzyme that converts angiotensinogen into antiotensin you is?
Renin is the enzyme that converts angiotensinogen into angiotensin I in the renin-angiotensin-aldosterone system.
The enzyme renin raises blood pressure by activating the?
renin activates angiotensin in the blood
Where is renin synthesized?
Renin is primarily synthesized and secreted by the juxtaglomerular cells in the kidneys. These cells are located in the afferent arterioles of the renal nephrons and play a key role in regulating blood pressure and fluid balance through the renin-angiotensin-aldosterone system.
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.
Which enzyme is secreted by the juxtaglomerular apparatus?
Renin is the enzyme secreted by the juxtaglomerular apparatus.
What is a renin stimulation test?
The renin stimulation test is performed to help diagnose and distinguish the two forms of hyperaldosteronism.
The enzyme renin is responsible for the activation of what?
Renin is responsible for the activation of angiotensinogen into angiotensin I in the renin-angiotensin-aldosterone system, which plays a key role in regulating blood pressure and fluid balance in the body.
Is renin a hormone?
by function is enzyme ... by structure is hormone
