BIO 669 Quiz 6 Questions and Answers
The renal blood flow and this GFR are kept relatively consistent by: - ANSWER-
Myogenic (intrinsic) autoregulation
Which of the following is NOT a consistent finding in nephrotic syndrome? - ANSWER-
Hypertension and vasoconstriction
Which of the following does not stimulate aldosterone release? - ANSWER-Arterial
natriuretic peptide
Assume that fluid enters the distal tubule with an osmolarity of 100 mOsm, and that the
maximum osmolarity of medullary interstitial fluid is 1100 mOsm. As plasma ADH levels
rise, the osmolarity of the urine: - ANSWER-Approaches 1100 mOsm as an upper limit
The outer capillary epithelium is composed of __________ which fit with others to form
filtration slits. - ANSWER-Podocytes
Urine does not reflux (flow back up ) into the ureter because: - ANSWER-The lower end
of the ureter compressed by the detrusor muscle during micturition
An increase in renal vein and thus capillary, hydrostatic pressure is most likely to have
what effect on GFR? - ANSWER-Decreased GFR
Glucose reabsorption occurs primarily in the: - ANSWER-Proximal convoluted tubule
The low hydrostatic pressure, high oncotic (osmotic) pressure that allow for
reabsorption of valuable substances form the filtrate are the: - ANSWER-Peritubular
capillaries
The biggest stimulus (driver) of renin release is: - ANSWER-Decreased Na+
concentration in the distal tubules

Hypertension
Which signs and symptoms best fit nephrotic syndrome? - ANSWER-Hematuria with
casts, HTN, and mild proteinuria
