  8. electrolyte
    chemical element that carries an electrical charge when dissolved in water; necessary for functioning of muscles and nerves. kidneys maintain proper balance of this element and water in the blood

  10. filtration
    process whereby some substances, but not all, pass through a filter

    enclosing structure surrounding each glomerulus. aka Bowman's capsule. collects all the material that is filtered from the blood through the walls of the glomerulus
  12. glomerulus (plural glomeruli)
    tiny ball of capillaries (microscopic blood cells) in the kidney
  13. hilum
    depression in an organ where blood vessels and nerves enter and leave
  14. kidney
    one of two bean shaped organs on either side of the backbone in the lumbar region; it filters nitrogenous wastes from the blood stream to form urine
  15. meatus
    opening or canal

    inner region of an organ
  17. medullary cavity
    long bones in the innermost part containing red and yellow marrow
  18. nephron
    combination of glomerulus and renal tubule where filtration, reabsorption, and secretion take place in the kideny; functional unit of the kidney, each capable of forming urine by itself; aprox. 1 million in each kidney
  19. nitrogenous waste
    substance containing nitrogen excreted in the urine; ex: urea, uric acid, and creatinine
  20. potassium (K+)
    electrolyte regulated by the kidney so that proper concentration is maintained within the blood. essential for allowing muscle contraction and conduction of nervous impulses
  21. reabsorption
    process whereby renal tubules return materials necessary to the body back into the blood stream
  22. renal artery
    blood vessel that carries blood to the kidney
  23. renal pelvis
    central collecting region in the kidney
  24. renal tubule
    microscopic tube in the kidney where urine is formed after filtration
  25. renal vein
    blood vessel that carries blood away from the kidney and toward the heart
  26. renin
    hormone secreted by the kidney; it raises blood pressure by influencing vasoconstriction (narrowing of blood vessels)
  27. sodium (Na+)
    electrolyte regulated in the blood and urine by the kidneys; needed for proper transmission of nerve impulses, heart activity, and other metabolic functions
  28. trigone
    triangular area in the urinary bladder
  29. urea
    major nitrogenous waste excreted in urine
  30. ureter
    one of the two tubes leading from the kidneys to the urinary bladder
  31. urethra
    tube leading from the urinary bladder to the outside of the body
  32. uric acid
    nitrogenous waste excreted in the urine
  33. urinary bladder
    hollow, muscular sac that holds and stores urine
  34. urination (voiding)
    process of expelling urine; aka micturition
