What is renin? Renin is an enzyme made by special cells in your kidneys. It’s part of the renin-angiotensin-aldosterone system — a chain reaction designed to regulate your blood pressure. Specifically, renin controls the production of aldosterone, a hormone made …

Renin (etymology and pronunciation), also known as an angiotensinogenase, is an aspartic protease protein and enzyme secreted by the kidneys that participates in the body's renin-angiotensin-aldosterone system (RAAS)—also known as the renin-angiotensin-aldosterone axis—that increases the volume of extracellular fluid (blood plasma, lymph ...

2023年5月16日 · Is your blood pressure still high, despite medication and a healthy lifestyle? Find out what a renin test can tell you.

2022年9月13日 · The renin–angiotensin–aldosterone system (RAAS) is a critical regulator of blood volume and systemic vascular resistance on a long-term basis. The baroreceptor reflex, on the other hand, responds in a short-term manner to decreased blood pressure.

2023年3月12日 · The renin-angiotensin-aldosterone system (RAAS) is a critical regulator of blood volume, electrolyte balance, and systemic vascular resistance. While the baroreceptor reflex responds in the short-term to decreased arterial pressure, the RAAS is responsible for acute and chronic alterations.

renin-angiotensin system, physiological system that regulates blood pressure. Renin is an enzyme secreted into the blood from specialized cells that encircle the arterioles at the entrance to the glomeruli of the kidneys (the renal capillary networks that are the filtration units of the kidney).

A renin test (or renin and aldosterone test) is used to find out if your adrenal glands are making too much or too little aldosterone. The test is especially useful in diagnosing primary aldosteronism (PA), a disease caused by having too much aldosterone.

2023年1月30日 · Renin is an aspartyl protease released by the juxtaglomerular cells of the kidneys in response to perceived low blood pressure and renal perfusion. It plays an essential role in the rate-limiting step of the renin-angiotensin-aldosterone system (RAAS), responsible for blood volume homeostasis and mean arterial blood pressure.

renin-angiotensin system, physiological system that regulates blood pressure. Renin is an enzyme secreted into the blood from specialized cells that encircle the arterioles at the entrance to the glomeruli of the kidneys (the renal capillary networks that are the filtration units of the kidney).

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.
