Raas pathway
The renin–angiotensin system (RAS), or renin–angiotensin–aldosterone system (RAAS), is a hormone system that regulates blood pressure, fluid and electrolyte balance, and systemic vascular resistance. When renal blood flow is reduced, juxtaglomerular cells in the kidneys convert the precursor … See more The system can be activated when there is a loss of blood volume or a drop in blood pressure (such as in hemorrhage or dehydration). This loss of pressure is interpreted by baroreceptors in the carotid sinus. … See more In the fetus, the renin–angiotensin system is predominantly a sodium-losing system, as angiotensin II has little or no effect on aldosterone levels. Renin levels are high in the fetus, while angiotensin II levels are significantly lower; this is due to the limited pulmonary … See more • Discovery and development of angiotensin receptor blockers See more • Banic A, Sigurdsson GH, Wheatley AM (1993).

S2CID See more Angiotensin I may have some minor activity, but angiotensin II is the major bio-active product. Angiotensin II has a variety of effects on the body: • Throughout … See more Locally expressed renin–angiotensin systems have been found in a number of tissues, including the kidneys, adrenal glands, the heart, vasculature and nervous system, … See more • ACE inhibitors of angiotensin-converting enzyme are often used to reduce the formation of the more potent angiotensin II. Captopril is an example of an ACE inhibitor. ACE cleaves a number of other peptides, and in this capacity is an important regulator … See more WebThe natriuretic peptide system. The natriuretic peptide system counter regulates the detrimental effects of the upregulation of RAAS that occurs in HF-REF, inhibits secretion of arginine vasopressin and modulates the autonomic nervous system in ways that are likely to be beneficial in this syndrome.5 Sodium and water retention and vasoconstriction caused …
