Aldosterone afferent arteriole
The afferent arterioles are a group of blood vessels that supply the nephrons in many excretory systems. They play an important role in the regulation of blood pressure as a part of the tubuloglomerular feedback mechanism. The afferent arterioles branch from the renal artery, which supplies blood to the kidneys. The afferent arterioles later diverge into the capillaries of the glomerulus. WebThe renin-angiotensin-aldosterone system (RAAS) plays an important role in regulating blood volume and systemic vascular resistance, which together influence cardiac output …

WebA2. The juxtaglomerular apparatus is a specialized structure found in the kidneys, located between the afferent arteriole and the distal convoluted tubule. Its primary function is to regulate blood pressure and glomerular filtration rate (GFR) in the kidneys. It does this by secreting the hormones renin and angiotensin II, which act on the ... WebSep 1, 2024 · The renin-angiotensin-aldosterone system regulates salt and, in part, water homeostasis, and therefore blood pressure and fluid balance through its actions on the heart, kidneys, and blood vessels. 2 Drugs that target this system—angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs)—are used primarily …
WebAldosterone, often called the “salt-retaining hormone,” is released from the adrenal cortex in response to angiotensin II or directly in response to increased plasma K+. It promotes Na+ reabsorption by the nephron, … Web221. All of the following are mechanisms of renal autoregulation of GFR EXCEPT: a. Sympathetic stimulation of afferent arterioles b.
