Biol 373 quiz 4ab Exam Questions and
Answers (Latest 2026)
The vasculature of mammalian kidneys is unusual because -
Correct Answers ✅Each nephron has glomerular and
peritublar capillary beds connected by an efferent arteriole
What happens to renal blood flow when the afferent arteriole
is constricts? - Correct Answers ✅It decreases
What happens to glomerular filtration rate (GFR) when the
afferent arteriole constricts? - Correct Answers ✅It
decreases
What happens to glomerular filtration rate (GFR) when the
Efferent arteriole constricts? - Correct Answers ✅It
increases
In response to an increase in systemic arterial pressure you
can predict that... - Correct Answers ✅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 Answers ✅The
ascending limb of the loop of hence where it connects with
the distal tubule
, Biol 373 quiz 4ab Exam Questions and
Answers (Latest 2026)
Which of the following monitors tubular salt concentrations
and can release paracrine factors that affect afferent arteriole
diameter? - Correct Answers ✅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 Answers ✅entering the proximal tubule
Na+ - Correct Answers ✅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 Answers ✅- ENac
channels
- symporters that couple amino acid and Na+ transport
- sodium-glucose cotransporters (SGLTs)
glucose reabsorption across the epithelium of the proximal
tubule is accomplished by ... - Correct Answers ✅-
transport across the apical membrane AGAINST its
concentration gradient, coupled with Na+
- facilitated diffusion across the basolateral membrane DOWN
its concentration gradient
