This renal-adjusting hormone cannot be stored within the cells where it is synthesized.

A anti-diuretic hormone
B aldosterone
C renin
D angiotensin II
E atrial natriuretic peptide

B

2

If ATP production in a human kidney was suddenly halted, urine production would

A increase, and the urine would be isoosmotic compared to plasma.

B decrease, and the urine would be isoosmotic compared to plasma.

C increase, and the urine would be hyperosmotic compared to plasma.

D decrease, and the urine would be hypoosmotic compared to plasma.

E come to a complete halt.

A

3

Where and when does osmolarity of the filtrate increase?


A As the filtrate moves through the proximal tubule
B As the filtrate moves up to the cortex in the ascending limb of the loop

C As the filtrate moves down the descending limb of the loop of Henle

C

4

The high osmolarity of the renal medulla is maintained by all of the following except


A active transport of salt from the upper region of the ascending limb.
B diffusion of salt from the thin segment of the ascending limb of the loop of Henle.

C diffusion of urea from the collecting duct.

D the spatial arrangement of juxtamedullary nephrons.
E diffusion of salt from the descending limb of the loop of Henle.

E

5

Aldosterone is _____. 


A a protein hormone that decreases blood pressure without changing blood volume

B decreases water reabsorption in the kidneys

C is released in great quantities when ethanol intoxication takes place 

D a steroid hormone that reduces the amount of fluid excreted in the urine 
E triggers the conversion of angiotensinogen into angiotensin II

D

6

Under the influence of antidiuretic hormone (ADH), _____ is produced.


A urine containing more glucose 

B bloody urine

C urine containing a lower concentration of urea 

D more concentrated urine 

E Less concentrated urine

D

7

The filtrate in the renal pelvis enters directly from 


A the collecting duct.

B the loop of Henle. 

C Bowman's capsule. 

D the glomerulus. 

E the proximal tubul

A

8

Which regions of the nephron function independently of hormonal control for the most part?


A Renal corpuscle and collecting duct. 

B Proximal tubule, loop of Henle, and distal tubule. 

C Renal corpuscle, proximal tubule, and loop of Henle. 

D Distal tubule and collecting duct.

C

9

What is the difference between a countercurrent multiplier system, such as the one involving the loop of Henle, and the countercurrent systems that maximize oxygen absorption by fish gills or reduce heat loss in endotherms? 


A A countercurrent multiplier system, such as the one involving the loop of Henle, involves movement of ions rather than movement of oxygen or heat transfer. 

B Unlike the other countercurrent systems, a countercurrent multiplier system, such as the one involving the loop of Henle, expends energy in active transport.

C A countercurrent multiplier system, such as the one involving the loop of Henle, includes a capillary bed.

B

10

Which of the following events occurs at the onset of the luteal phase of the menstrual cycle? 


A Development of the corpus luteum. 

B Shedding of the endometrium.

C Release of high levels of FSH.

D Maturation of the follicle.

A

11

Which hormone spikes midway through the menstrual cycle and triggers ovulation?


A Progesterone.

B Luteinizing hormone (LH).

C Follicle-stimulating hormone (FSH).

D Estradiol.

B

12

After ovulation, high levels of _____ inhibit _____ secretion.


A estrogen and progesterone ... FSH and LH 

B FSH and LH ... estrogen and progesterone 

C HCG ... estrogen and progesterone 

D estrogen ... FSH 

E androgens ... FSH and LH

A

13

Prior to ovulation, the primary steroid hormone secreted by the growing follicle is


A GnRH. 

B LH. 

C FSH.

D estradiol.

E inhibin.

D
