    Kidneys
  3. Other than filter blood, whatt other functions are there for the kidneys?
    Maintain the electrolyte, acid-base, and fluid balances in the body
  4. What is the process called that moves urine through the ureters into the urinary bladder?
    Peristalsis
  5. From the urinary bladder, the urine travels through a short pipe called the ___a___ and is ultimately voided through the ____b____.
    • a) urethra
    • b) external urethral orifice
  6. What is the scientific term for urinating?
    micturition
  7. The kidneys and ureters are ___a___(retroperitoneal/subperitoneal?) while the bladder and uterus are ___b____ (retroperitoneal/subperitoneal?).
    • a) retroperitoneal
    • b) subperitoneal
  8. T or F: the left kidney is positioned slighty lower than the right one since it's crowded by the large liver.
    False: the right kidney is positioned slightly lower thanthe left.
  9. What are the 3 layers of support in the kidneys?
    • From deep to superficial: 
    • 1. fibrous capsule

    • g) renal pelvis
    • h) renal vein
    • i) hilum of kidney
    • j) renal artery
    • k) major calyx
  11. The production of urine starts here.
    renal cortex
  12. How does urine start and end in the kidneys?
    • 1. Starts in the RENAL CORTEX
    • 2. drains to the RENAL PYRAMIDS
    • 3. It is then delivered into the MINOR CALYCES...
    • 4. which collect into larger MAJOR CALYCES
    • 5. it then empties into the RENAL PELVIS
    • 6. and is dumped into the URETER
    • a) internal urethral sphincter
    • b) external urethral sphincter
  13. B not important
    • a) vas deferens
    • b) 
    • c) tunica vaginalis
    • d) testis
    • e) epididymis
    • f) spermatic cord
    • a) tunica albuginea
    • b) epididymis
  14. What are the main functions of the testes?
    • 1) produce sperm
    • 2) produce testosterone
  15. What covers each testes?
    • The tunica vaginalis and tunica albuginea
  16. The temperature in the testes must be at what temp to produce sperm?
    35 degrees celcius
  17. What are the three mechanisms in the scrotum to help regulate temperate for sperm production?
    • 1. cremaster muscle
    • 2. dartos muscle
    • 3. pampiniform plexus
  18. This part of the testes is derived from the inernal abdominal oblique and found in the spermatic cord
    cremaster muscle
  19. What 2 muscles, when the testes are cold, contracts and raises it closer to the body?
    • cremaster muscle
    • dartos muscle
  20. This muscle makes the skin of the scrotum wrinkle and holds the testes snugly against the warm boy.
    Dartos muscle
  21. This is a venous network that surrounds the testicular artery and forms a countercurrent heat exchanger
    pampiniform plexus
  22. This process is whe the arterial blood in the testest is cooled by the venous blood from the scrotum, and vice versa.
    countercurrent heat exchanger
  23. This ontains the ductus deferens, blood and lymhatic vessels and testicular nerves
    • spermatic cord
  24. The spermatic cord enters the pelvis through this.
