The renin-secreting cells, which compose the juxtaglomerular apparatus, are sensitive to changes in blood flow and blood pressure. When renin is released by the kidneys into the bloodstream, it converts angiotensinogen, a protein produced by the liver, into angiotensin I [ 5, 3 ]. Next, an enzyme produced in the lungs called angiotensin-converting enzyme (ACE) converts angiotensin I into angiotensin II. Renin converts angiotensinogen, which is produced in the liver, to the hormone angiotensin I. An enzyme known as ACE or angiotensin-converting enzyme found in the lungs metabolizes angiotensin I into angiotensin II. Angiotensin II causes blood vessels to constrict and blood pressure to increase. Renin is secreted by the kidney, but its involved in arterial vasoconstriction (outside of kidney cells), so it is a hormone. And its also a peptide/enzyme, so it is considered both a hormone and an enzyme Renin is a central hormone in the control of blood pressure and various other physiological functions. In spite of the very early discovery of renin over 100 years ago, we have only recently gained a deeper understanding of the origin of renin-producing cells and of the mechanisms responsible for renin synthesis and secretion.

I njurarna finns små grupper av hormonbildande celler. De bildar hormonerna renin och erytropoetin. Renin höjer blodtrycket och blodflödet. Renin utsöndras när blodtrycket är så lågt att njurarna får för lite blod.
