wat stimulates renin secretion
Renin is a peptide hormone secreted by the kidneys. It functions in the renin-angiotensin system (RAS) which regulates extracellular fluid volume and arteriol blood pressure.As with other peptide hormones, the production and secretion of renin is tightly regulated by physiological processes within the body.fter renin is released from the kidney, it breaks down angiotensinogen into angiotensin I. This peptide is then broken down further into angiotensin II, which acts as a vasoconstrictor narrowing the blood vessels.
