15 sty 2014 · The afferent arteriole has features of phasic smooth muscle, whereas the efferent arteriole has features of tonic smooth muscle. In the splanchnic circulation, the portal vein and hepatic artery are arranged in parallel and supply blood for detoxification and metabolism to the liver.
Mitochondrial H2O2 contributes to flow-mediated dilation (FMD) in human coronary arterioles (HCA). We examined the hypothesis that the endothelial cytoskeleton plays a critical role in transducing endothelial wall shear stress into a stimulus for ...
The efferent arterioles form a convergence of the capillaries of the glomerulus, and carry blood away from the glomerulus that has already been filtered. They play an important role in maintaining the glomerular filtration rate despite fluctuations in blood pressure .
1 lut 2006 · The plasma concentrations of ANP and BNP are elevated in heart failure, and they are considered to compensate for heart failure because of their diuretic, natriuretic, and vasodilating actions and inhibitory effects on renin and aldosterone secretion.
17 lip 2023 · An increase in hydrostatic pressure in the afferent arteriole stretches vascular smooth muscle, activating inward directed ion channels, leading to depolarization and contraction. This prevents pathologic increases in RBF that would damage the kidney.
2 lut 2021 · Atrial natriuretic peptide (ANP) is a cardiac peptide with multiple physiological effects, including natriuresis, blood pressure regulation, and renin-angiotensin-aldosterone system (RAAS)...
13 sty 2023 · Afferent and efferent arterioles transport blood in and out of the glomerulus. Hypovolemia-induced reduction in glomerular filtration leads to decreased flow of NaCl to specialized epithelial cells (macula densa). This, in turn, sends signals to the adjacent afferent arteriole to vasodilate and increase glomerular filtration.
