Final Exam 4
9. Place the regions of the nephron in the correct order for the process of urine formation (a. capsular space of glomerulus b. nephron loop c. collecting duct d. distal convoluted tubule e. proximal convoluted tubule a. a, c, b, c, d b. e, d, b, a, c c. b, e, c, d, a d. a, e, b, d, c)
(a, e, b, d, c) capsular space of glomerulus; proximal convoluted tubule; collecting duct; nephron loop; proximal convoluted tubule;
How are the processes of reabsorption and secretion related? (a. They both involve movement of material from the blood into the tubular fluid b. Materials move in opposite directions: reabsorption moves materials into the blood; whereas secretion removes from the blood. c. Materials move in opposite directions: secretion moves material into the blood, whereas reabsorption removes them from the blood. d. They both involve movement of material from the tubular fluid into the blood.)
Materials move in opposite directions: reabsorption moves materials into the blood; whereas secretion removes from the blood.
2. Which is NOT a function of the kidneys? (a. regulation of blood pressure b. removal of wastes from the blood c. regulation of erythrocyte production d. Regulation of lymphocyte production)
Regulation of lymphocyte production
6. Which is not correct regarding nephrons? ( a. The renal corpuscle may be located in the renal cortex or renal medlla b. The renal corpuscle includes the glomerulus and the glomerular capsule c. The renal tuble is composed of the proximal convoluted tubule, nephron loop, and distal convoluted tuble.) d. The nephron is the functional filtration unit in the kidney
The renal corpuscle may be located in the renal cortex or renal medlla
8. In the process of urine formation, first (a. filtrate if formed b. tubular fluid is formed, then filtrate, then urine c. none of the above)
filtrate if formed
5. Which class of nephron is crucially important in establishing a salt concentration gradient in the kidney so that urine concentration can be regulated? (a, intercalated nephron b. juxtamedullary nephron c. adrenal nephrons d. cortical nephrons)
juxtamedullary nephron
1. What is the correct sequence of organs for the formation and elimination of urine? ( a. bladder, urethra, kidney, ureter b. kidney, ureter, bladder, urethra c. kidney, urethra, bladder, ureter d. kidney, bladder, ureter, urethra)
kidney, ureter, bladder, urethra
3. Which of the following choices lists structures in the order in which urine flows through them? ( a. major calyx, minor calyx, renal pelvis b. renal pelvis, major calyx, minor pelvis c. minor calyx, major calyx, renal pelvis d. major pelvis, minor calyx, renal pelvis)
minor calyx, major calyx, renal pelvis
4. The renal corpuscle is located within the ( a. collecting duct b. renal medulla c. renal cortex d. renal pelvis)
renal cortex
13. generally, negatively charged plasma proteins are (a. moved across the filtration membrane by active transport pumps. b. attracted by the positive charge of the filtration membrane c. repelled by the negative charge of the filtration membrane d. engulfed by endocytosis and reabsorbed at the filtration membrane. )
repelled by the negative charge of the filtration membrane
7. Fluid contained within the lumen of a nephron loop is called (a. plasma b. tubular fluid c. filtrate d. urine)
tubular fluid
12. The active transport of solutes out of the blood and into the tubular fluid is called (a. filtrations b. tubular reabsorption c. tubular secretion d. titration )
tubular secretion
10. Urine passes from the renal papilla into a ( a. collecting duct, then minor calyx, then to a major calyx. b. major calyx, then to a minor calyx, them to a wreter c. minor calyx, then to major calyx, then to the renal pelvis d. ureter, then to a minor calyx, then to a major calyx)
ureter, then to a minor calyx, then to a major calyx
