B. the renal medulla

C. the renal pelvis

D. all of the above

10. True or false. The renal cortex contains cone-shaped tissue masses

called renal pyramids.

A. cortex

B. medulla

C. pelvis

D. loop of the nephron

12. True or false. Microscopically, the kidney is composed of over one

million nephrons.

13. Nephrons are sometimes called __________.

D. glomerular capsules

14. Each nephron in the kidney is made up of several parts, including

____________.

A. glomerular capsule

B. the proximal convoluted tubule

C. the loop of the nephron

D. all of the above

15. True or false. The glomerular capsule and the convoluted tubule lie

outside the renal cortex.

B. selective reabsorption

C. tubular excretion

D. all of the above

19. True or false. The pattern of blood flow about the nephron is critical

to urine formation.

20. The filterable components of the blood that move across from the

glomerulus are________.

capsule.

A. a descending

B. an ascending

C. both ascending and descending

D. convoluted

26. True or false. Water cannot leave the ascending limb of the loop of the nephron because the limb is impermeable to water.
