and tissue metabolism
Renal artery is very _____, blood in kidney's moves with ____ pressure,
which is necessary for filtration
Ans: short; high
Juxtaglomerular Apparatus large scale function is controlling _____
________
Ans: blood pressure (by controlling renal blood flow and
filtration)

Ans: sodium-sensing cells located between the afferent and
efferent arterioles of distal convoluted tubule;
Juxtaglomerular cells and macula densa form the juxtaglomerular
apparatus (JGA) that controls _____ _____ ____ and__________
__________ .
Ans: renal blood flow (RBF); glomerular filtration
_____ secretion occurs at the JGA
Ans: Renin
Renal Blood Flow Throughout the Nephron
Ans: Renal artery
afferent arteriole

The fluid filtered by the glomerular capillary filtration membrane and
released into the proximal convoluted tubule is _______ free but
contains ____________ and _______ _________ in the same
concentrations as found in plasma
Ans: protein; electrolytes (i.e. sodium chloride and potassium);
organic molecules (i.e. creatinine urea and glucose)
In the glomerulus, the ________ ________ determines permeability of
glomerular capillary membrane
Ans: Basement membrane
What does glomerular filtration depend on (3)?
Ans: •Size and charge of substances
•Hydrostatic pressure in the capillaries
•Oncotic pressure in the capillaries
Between BP ___ - ____ mmHg the kidneys maintain a constant GFR
Ans: 80-180
Autoregulation of renal blood flow:
Response to increased systemic BP
All rights reserved © 2025/ 2026 |
, Page |4
Ans: Afferent arterioles constrict, preventing an increase in
filtration pressure.
Autoregulation of renal blood flow:
Response to decreased systemic BP
Ans: GFR decreases and the amount of sodium in macula densa
decreases
•RAAS activated
•Vasoconstriction, increase in sodium and water reabsorption,
BP returns to norm
________ is a good index of renal function, ______ is a good index for
hydration
Ans: creatinine; BUN
Creatinine is most valuable for monitoring the progress of chronic
rather than acute renal disease.
Ans:
Aging and Renal Function: (increased or decreased) excretion of
glucose
