part of negative regulation of renal output by angiotensin negative regulation of glomerular filtration negative regulation of glomerular filtration by angiotensin regulation of glomerular filtration by angiotensin angiotensin-mediated regulation of glomerular filtration GO:0003106 The process in which angiotensin directly decreases the rate of glomerular filtration in the kidney. Glomerular filtration is the process whereby blood is filtered by the glomerulus into the renal tubule. biological_process
