Angiotensin is a peptide hormone that causes vasoconstriction and an increase in blood pressure.It is part of the renin–angiotensin system, which regulates blood pressure.Angiotensin also stimulates the release of aldosterone from the adrenal cortex to promote sodium retention by the kidneys.. An oligopeptide, angiotensin is a hormone and a dipsogen.

Increased renal Na + reabsorption and impaired pressure natriuresis are major contributors to the development of high blood pressure and are associated with increased Ang II and Aldo levels. Both Ang II and Aldo can promote Na + and fluid retention through activation of renal AT-1R and MR receptors, respectively.

Hormonal cues help the kidneys synchronize the osmotic needs of the body. Hormones like epinephrine, norepinephrine, renin-angiotensin, aldosterone, anti-diuretic hormone, and atrial natriuretic peptide help regulate the needs of the body as well as the communication between the different organ systems. The renin-angiotensin-aldosterone system (RAAS) plays an important role in regulating blood volume and systemic vascular resistance, which together influence cardiac output and arterial pressure. As the name implies, there are three important components to this system: 1) renin, 2) angiotensin, and 3) aldosterone.

Interrelationship between renin-angiotensin-aldosterone system and oxidative stress in chronic heart failure patients with or without renal impairment Biomed Pharmacother . 2021 Jan;133:110938. doi: 10.1016/j.biopha.2020.110938.

Renin cleaves angiotensinogen, which is released by the liver, to form angiotensin I. 2020-06-29 Pharmacologic blockade of the RAAS not only improves blood pressure, but alsohas a beneficial impact on inflammation, oxidative stress, insulin sensitivity, and glucose homeostasis. Several strategies are available for RAAS blockade, including ACE inhibitors, ARBs, and MR blockers, which have been proven in the clinical trials to result in improved CVD and CKD outcomes. Chronic activation of the renin-angiotensin-aldosterone system (RAAS) promotes and perpetuates the syndromes of congestive heart failure, systemic hypertension, and chronic kidney disease. Excessive circulating and tissue angiotensin II (AngII) and aldosterone levels lead to a pro-fibrotic, -inflammatory, and -hypertrophic milieu that Journal of the Renin-Angiotensin-Aldosterone System (JRAAS) is a peer-reviewed open access journal which focuses on the normal and abnormal function of the renin-angiotensin-aldosterone system and its pharmacology and therapeutics, mostly in a cardiovascular context but including research in all areas where this system is present, including the brain, lungs and gastro-intestinal tract.

Aldosterone is part of the renin–angiotensin–aldosterone system. It has a plasma half-life of less than 20 minutes. [6] Drugs that interfere with the secretion or action of aldosterone are in use as antihypertensives, like lisinopril , which lowers blood pressure by blocking the angiotensin-converting enzyme (ACE), leading to lower aldosterone secretion.
