UTA A&P II LECTURE; FINAL EXAM CH. 26-29 | 100% VERIFIED
The urinary system does all of the following, except that it
A) excretes excess albumen molecules.
B) regulates plasma concentrations of electrolytes.
C) regulates blood volume.
D) contributes to stabilizing blood pH.
E) eliminates organic waste products. - A) excretes excess albumen molecules.
4) Glomerular (Bowman's) capsule and the glomerulus make up the
A) collecting tubule system.
B) renal papilla.
C) renal corpuscle.
D) nephron loop (loop of Henle).
E) renal pyramid. - C) renal corpuscle.
7) The primary function of the proximal convoluted tubule is
A) absorption of ions, organic molecules, vitamins, and water.
B) secretion of drugs.
C) filtration.
D) adjusting the urine volume.
E) secretion of acids and ammonia. - A) absorption of ions, organic molecules,
vitamins, and water.
10) The process of filtration is driven by
A) blood osmotic pressure.
B) renal pumping.
C) blood hydrostatic pressure.
D) active transport.
E) solvent drag. - C) blood hydrostatic pressure.
11) Under normal conditions, glomerular filtration depends on three main pressures:
1) blood hydrostatic pressure
2) capsular hydrostatic pressure
3) capsular colloid osmotic pressure
4) blood colloid osmotic pressure
5) urinary bladder hydrostatic pressure
A) 2, 4, and 5 are correct.
, B) 2, 3, and 4 are correct.
C) 1, 2, and 3 are correct.
D) 3, 4, and 5 are correct.
E) 1, 2, and 4 are correct. - E) 1, 2, and 4 are correct.
14) The ability to form a concentrated urine depends on the functions of
A) the distal convoluted tubule.
B) the proximal convoluted tubule.
C) the collecting duct.
D) the nephron loop (loop of Henle).
E) both C and D - E) both C and D
16) The conversion of ammonia into a less toxic substance produces
A) acetyl-CoA.
B) urea.
C) ketone bodies.
D) nitrate.
E) water - B) urea.
17) Chloride ion is reabsorbed in the ascending limb by
A) simple diffusion.
B) active transport.
C) countertransport for bicarbonate ion.
D) cotransport with Na and K ions.
E) facilitated diffusion. - D) cotransport with Na and K ions.
20) When the level of ADH (antidiuretic hormone) decreases,
A) more urine is produced.
B) less urine is produced.
C) the osmolarity of the urine decreases.
D) both A and C
E) both B and C - D) both A and C
24) One mechanism the kidney uses to raise systemic blood pressure is to
A) decrease filtration into glomerular capsule.
B) increase secretion of renin by the juxtaglomerular complex.
C) increase release of angiotensin II by the suprarenal glands.
D) decrease secretion of aldosterone.
E) decrease urinary albumin concentration. - B) increase secretion of renin by the
juxtaglomerular complex.
27) Measurement of the functions of a nephron reveals a glomerular capillary pressure
of 69 mm Hg, and a pressure in the capsular space of 15 mm Hg. Assuming that the
colloid osmotic pressure is 30 mm Hg, and that essentially no plasma proteins are
filtered by the glomerulus, what is the net filtration pressure in this case?
