• Glomerular filtrate is nearly protein free (T or F)

  true
• Whenever sodium ions are reabsorbed through the wall of the renal tubule by active transport the chloride ions are

  reabsorbed passively by electrical attraction
• Shock-wave lithotripsy is a procedure for

  fragmenting kidney stones.
• Gout is a condition in which the plasma has an abnormally high concentration of

  uric acid.

  plasma proteins.
• Glomerular filtrate has a composition similar to tissue fluid. (T or F)

  True 
• The ureters extend inferiorly

  behind the parietal peritoneum and join the urinary bladder from below.
• The stretch receptors of the micturition reflex are in the

  urinary bladder.
• When the concentration of water in body fluids increases, the secretion of ADH increases. (T or F)

  False 
• Which of the following is an abnormal constituent of urine?

  creatinine,  urea,  uric acid,  water, :  none of these
• The urethra transports urine from the kidney to the urinary bladder. (T or F)

  False 
• The effector of the micturition reflex is the

  detrusor muscle.
• Uric acid results from the metabolism of nucleic acids. (T or F)

  True 
• Cystitis occurs more commonly in women than in men because the

  female urethra is shorter than that of the male.
• Whenever sodium ions are reabsorbed through the wall of the renal tubule by active transport, the chloride ions are

   reabsorbed passively by electrical attraction.
• Glomerular filtrate is nearly protein free. (T or F)

  True
• Urine formation involves

  tubular reabsorption.  glomerular filtration.  tubular secretion.
• Which of the following is correct concerning the location of the kidneys?

  They are located behind the parietal peritoneum.
• Kidney stones are least likely to be composed of

  cholesterol.
• Which of the following indicates the parts of a renal tubule in the correct sequence from beginning to end?

  proximal convoluted tubule, descending limb of the nephron loop, ascending limb of the nephron loop, distal convoluted tubule
• The amount of testosterone produced is regulated by a positive feedback system.

   False 
• Undifferentiated spermatogenic cells are called

  spermatogonia.
• Which of the following can be fertilized to produce a zygote?

  secondary oocyte
• The hormone responsible for the development and maintenance of male secondary sexual characteristics is

  testosterone.
• In spermatogenesis, meiosis results in the formation of

  four sperm cells with 23 chromosomes each.
• The secretions of the prostate gland neutralize acidic semen. (T or F)

  True 
• Testicular cancer is most likely to originate from

   epithelial cells of the seminiferous tubules.
• Meiosis occurs during

   both spermatogenesis and oogenesis.
• The cells in the testis that produce male sex hormones are called

  interstitial cells.
• The head of a sperm consists mostly of

  the nucleus.
• The tail of a sperm cell is a ________.

  flagellum
• The tubular portion of the uterus that extends downward into the upper part of the vagina is the


  cervix.
• The endometrium is the inner layer of the

  uterus.
• A Pap smear is used to detect abnormal cells in the

   cervix.
• The hormone mainly responsible for the development and maintenance of female secondary sexual characteristics is

  estrogen.
• In the female reproductive cycle, menstrual flow occurs when the concentrations of

  estrogen and progesterone are low.
• Women athletes sometimes experience disturbances in their reproductive cycles because of

  decreased synthesis of estrogens.
• The primary organs of the female reproductive system are the uterus and vagina. (T or F)

  False 
• As a group, the structures of the female reproductive system that surround the openings to the urethra and vagina comprise the ________.

  vulva
• The fertilization of an egg occurs in the uterine tube. (T or F)

  True
