  1. Which of the following is correct concerning the location of the kidneys?
    they are located behind the peritoneum
  2. A renal corpuscle includes the
    glomerulus and glomerular capsule
  3. Which of the following indicates the parts of a renal tubule in the correct sequence from beginning to end?
    proximal convuluted tubule, descending limb, ascending limb, distal convoluted tubule
  4. If the Afferent arteriole that supplies blood to the glomerulus becomes constricted
    the glomerular filtration rate decreases
  5. Whenever the plasma glucose concentration exceeds the renal plasma threshold,
    glucose will appear in the urine
  6. The countercurrent mechanism functions primarily in the
    nephron loop
  7. The hormone ADH functions to promote water reabsorption through the walls of the
    distal convoluted tubule and collecting duct
  8. The largest quantity of hydrogen ions is secreted
    actively through the entire renal tubule
  9. The ureter extends downward
    behind the parietal peritoneum and joins the urinary bladder from below
  10. The micturation reflex center is located in the
    glandular urethra
  11. Which of the following is not part of the male urethra?
    glandular urethra
  12. Which of the following would increase the rate of glomerular filtration?
    constriction of efferent arteriole
  13. Which of the following is not considered a function of the kidneys?
    formation of plasma proteins
  14. Which of the following correctly lists the order of structures through which urine flows after its formation in the nephron?
    calyx, renal pelvis, ureter, urinary bladder, urethra
  15. The juxtaglomerular cells together with the macula densa are called the juxtaglomerular apparatus, which is important in regulating the secretion of
    Renin
  16. Which of the following is an abnormal constituent of urine?
    glucose
  17. Which of the following correctly describes the countercurrent mechanism of the nephron loop?
    water moves out of the descending limb; sodium moves out of the ascending limb
  18. The internal urethral sphincter is composed of ___ while the external sphincter is composed of ___
    smooth muscles, skeletal muscles
  19. Much of the sodium ions (Na+) are
    reabsorbed thruogh the wall of the renal tubule by active transport
  20. The vasa recta are branches from the pretubular capillary system are closely associated with
    the juxtamedullary nephrons
  21. The renal medulla is composed of conical masses of tissue called
    renal pyramids
  22. Most of potassium ions (K+) in the glomerular filtrate are actively reabsorbed in the proximal convoluted tubule, but some may be secreted in the distal convoluted tubule. Under the influence of Aldosterone, potassium ions are
    passively secreted in the renal distal convoluted tubule
  23. The inter lobar vein drains into
    the renal vein, to the vena cava
  24. What is the purpose of the countercurrent mechanism in the nephron?
    It creates a highly concentrated interstitial medulla fluid so that urine can be concentrated by the collecting ducts due to increase water reabsorption
  25. Aldosterone from the adrenal cortex causes sodium to be
    conserved and water to be conserved
