Was erfolgt im dialysator?
Der Dialysator ist das entscheidende Instrument für die Blutreinigung bei der Hämodialyse und ihren verwandten Verfahren. Hier finden die von der physiologischen Nierenfunktion abgeleite- ten Transportprozesse zur Reinigung des Bluts von Toxinen und zur Filtration von Wasser statt (⊳ Kap. 2.4.4).
Was bewirkt einen erhöhten kapillären filtrationsdruck?
Der effektive Filtrationsdruck ist der Druck im Kapillarbett, der als treibende Kraft den Flüssigkeitsaustausch im Gewebe und in der Niere bestimmt. Er legt fest, wieviel Blutplasma aus dem Kapillarbett in das Interstitium bzw. wieviel Primärharn durch die Glomeruli in die Harnwege filtriert wird.
What is the difference between the afferent and efferent arteriole?
The efferent arteriole (which carries blood away from the glomerulus) is smaller than the afferent arteriole.
How do the afferent and distal arterioles constrict?
Those cells in the distal tubule can also make the afferent arterioles constrict by releasing nitric oxide. By squeezing down into a smaller pathway, the afferent arterioles increase their local blood pressure and in the capillaries that they feed into.
What is the function of afferent arterioles in the kidney?
Distribution of bloodvessels in cortex of kidney. 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.
What is the function of afferent blood vessels?

The afferent arterioles are a group of blood vessels that supply the nephrons in many excretory systems.
