  30. when water is reabsorbed in proximal convoluted tubule by obligatory reabsorption, what does that mean?
    water is following sodium and other ions or molecules to maintain osmotic balance
  31. how does detrusor muscle help with urination?
    compresses urinary bladder and expels urine through urethra
  32. what organ was the first successful transplant?
    kidney
  33. what are major calyces?
    large branches of renal pelvis
  34. what structure embeds the kidney and acts like a cushion?
    adipose capsule
  35. what happens to parasympathetic motor neurons during micturition reflex?
    increased activity of parasympathetic motor neurons that control smooth muscle of bladder
  36. What anatomical structure is damaged when one has a floating kidney?
    renal fascia (this holds kidney in place)
  37. what is a floating kidney?
    what structure is damaged if this happens ?
    • floating kidney is when kidney is out of normal position.
    • renal fascia is damaged if this happens
