The Classical and Tissue RAS in Blood Pressure Regulation. The only known function of AGT is as substrate to renin. The N-terminal amino acids of mature AGT secreted by hepatocytes are cleaved intravascularly, first by renin released from juxtaglomerular cells, to yield the angiotensin-I decapeptide, and then by endothelial membrane–attached …Web

Your blood pressure is measured with a blood pressure cuff and recorded in millimeters of mercury (mmHg). A normal systolic blood pressure is 90 to 120 mmHg (the top number) while a normal diastolic pressure is 60 to 80 mmHg (the lower number). Your blood pressure is considered elevated when the systolic number is between 120 and 129.Web

High blood pressure can narrow and damage the arteries that supply blood to the heart. This damage is known as coronary artery disease. Too little blood flow to the heart can lead to chest pain, called angina. It can lead to irregular heart rhythms, called arrhythmias. Or it can lead to a heart attack.Web
