Biol 373 quiz 4ab
The vasculature of mammalian kidneys is unusual because - correct answer ✔✔Each nephron has
glomerular and peritubular capillary beds connected by an efferent arteriole
What happens to renal blood flow when the afferent arteriole is constricts? - correct answer ✔✔It
decreases
What happens to glomerular filtration rate (GFR) when the afferent arteriole constricts? - correct answer
✔✔It decreases
What happens to glomerular filtration rate (GFR) when the Efferent arteriole constricts? - correct answer
✔✔It increases
In response to an increase in systemic arterial pressure you can predict that... - correct answer
✔✔Constriction of afferent arterioles occurs and there is little or no change in GFR
What part of the nephron tubule is part of the juxtaglomerular apparatus? - correct answer ✔✔The
ascending limb of the loop of hence where it connects with the distal tubule
Which of the following monitors tubular salt concentrations and can release paracrine factors that affect
afferent arteriole diameter? - correct answer ✔✔Macula dense cells
As fluid moves within the tubules through the regions of the nephron, the fluid ______ is the most
similar in composition to plasma - correct answer ✔✔entering the proximal tubule
Na+ - correct answer ✔✔Is the ion that is commonly linked to indirect active transport during
reabsorption in nephrons
Na+ moves across the apical membrane of epithelial cells of the proximal tubule via - correct answer
✔✔- ENac channels
