- The GFR can be regulated by constriction and dilation of the afferent arterioles. (flashcardmachine.com)
- Sympathetic innervation causes constriction of the afferent arterioles. (flashcardmachine.com)
- As with most other capillary beds in the body, the constriction of afferent arterioles increases the arteriolar resistance, raising systemic arterial blood pressure and decreasing the blood flow. (wikipedia.org)
Kidneys4
- The afferent arterioles branch from the renal artery, which supplies blood to the kidneys. (wikipedia.org)
- If the efferent arterioles are constricted then the blood pressure in the capillaries of the kidneys will increase. (wikipedia.org)
- Inside our kidneys, the renal arteries diverge into the smaller afferent arterioles of the kidneys. (innerbody.com)
- In the kidneys, angiotensin II constricts glomerular arterioles, having a greater effect on efferent arterioles than afferent. (wikipedia.org)

Kidney1
- The afferent arteriole of the kidney is a unique vascular segment: it is the effector of the renal hemodynamic autoregulation. (dissertations.se)
Renin-angiot1
- When renal blood flow is reduced (indicating hypotension) or there is a decrease in sodium or chloride ion concentration, the macula densa of the distal tubule releases prostaglandins (mainly PGI2 and PGE2) and nitric oxide, which cause the juxtaglomerular cells lining the afferent arterioles to release renin, activating the renin-angiotensin-aldosterone system, to increase blood pressure and increase reabsorption of sodium ions into the bloodstream via aldosterone.
