Renin, an enzyme, circulates in the blood and reacts with a plasma protein produced by the liver called angiotensinogen. When angiotensinogen is cleaved by renin, it produces angiotensin I, which is then converted into angiotensin II in the lungs.

Renin is a protein released by special kidney cells when you have a decreased salt (sodium) level or low blood volume.Most often, the renin blood test is done at the same time as an aldosterone blood test to calculate the renin to aldosterone level.

Also Refer: Blood Pressure and its Symptoms. Importance of the Renin-Angiotensin System Renin is an aspartyl protease related to the pepsin family. Renin is the regulator of the renin–angiotensin–aldosterone cascade (see Fig. 1).It specifically cleaves an N-terminal decapeptide, angiotensin I, from the 70 kDa angiotensinogen produced and secreted into the circulation by the liver.Angiotensin I is further shortened to the octapeptide angiotensin II through the activity of the The liver creates and releases a protein called angiotensinogen. This is then broken up by renin, an enzyme produced in the kidney, to form angiotensin I. This form of the hormone is not known to have any particular biological function in itself but, is an important precursor for angiotensin II. Renin leads to Angiotensin being released which eventually leads to Aldosterone being released.

Thus, the kidneys control blood pressure and volume directly. Renin acts on angiotensinogen, which is made in the liver and converts it to angiotensin I . This is the currently selected item. Renin production in the kidneys. Activating angiotensin 2. Angiotensin 2 raises blood pressure.

Plasma renin then carries out the conversion of angiotensinogen, released by the liver, to angiotensin I. Angiotensin I is Se hela listan på verywellhealth.com renin a protein-splitting enzyme (sometimes called a hormone) secreted into the blood by the cells lining the efferent glomerular vessels of the kidney Renin combines with a protein from the liver to form ANGIOTENSIN which in turn stimulates the cortex of the ADRENAL GLAND to release ALDOSTERONE. Renin. Renin is part of the renin – angiotensin – aldosterone system (RAAS).

One of the functions of the kidney is to monitor blood pressure and take corrective action if it should drop. The kidney does this by secreting the proteolytic enzyme renin. Renin acts on angiotensinogen, a plasma peptide, splitting off a fragment containing 10 … - Peptide hormone - Increases permeability of water in the DCT Aldosterone: - Stimulated and released in zona glomerulosa of adrenal cortex - Steroid hormone - Increases permeability of sodium in DCT - Excretes potassium in urine Renin Release. Renin release occurs by exocytosis into the surrounding interstitium (601) and may then be taken up by peritubular capillaries or be distributed within the periarterial connective tissue sheaths, in a retrograde manner along the outside of intrarenal arterioles and arteries (316).
