WebSep 14, 2024 · While there are notable differences between CPB and CRRT, including blood flow rates (100–200 mL/min vs. 2–5 L/min) and underlying clinical contexts, it is possible that in CRRT, like CPB, platelet activation due to shear stress within the circuit or due to membrane interactions leads to microthrombi formation and microvascular … WebThis mechanism stimulates either contraction or relaxation of afferent arteriolar smooth muscle cells ( Table 25.7 ). Recall that the DCT is in intimate contact with the afferent and efferent arterioles of the glomerulus. Specialized macula densa cells in this segment of the tubule respond to changes in the fluid flow rate and Na + concentration.

WebBlood plasma enters the afferent arteriole and flows into the glomerulus, a cluster of intertwined capillaries.

WebNov 12, 2012 · A reduction in ECF volume e.g. haemorrhage, leads to sympathetic nervous system (SNS) activation, a decreased blood flow through renal afferent arterioles and a reduced GFR and nephron tubular fluid flow. These three effects stimulate renin release and hence increase angiotensin II concentration (see part 1 of this tutorial). WebA Nephron.
