Transcript

  • 1. Homeostasis <ul><li>The kidney </li></ul><ul><li>The gross structure of the urinary system </li></ul>
  • 2. Introduction <ul><li>• The urinary system rids the body of waste materials and controls the volume and composition of body fluids. </li></ul><ul><li>Highly specialized cells in the kidneys are essential to these processes. </li></ul>
  • 3. Introduction <ul><li>• The urinary system is composed of paired kidneys and ureters, the urinary bladder, and the urethra. </li></ul><ul><li>• Urine is produced in the kidneys, and then drains through the ureters to the urinary bladder, where the urine is stored. </li></ul><ul><li>Urine is eliminated from the body through the urethra. </li></ul>
  • 4. The Urinary System
  • 5. The Urinary System The kidney
  • 6. The Urinary System The kidney ureter
  • 7. The Urinary System The kidney ureter bladder
  • 8. The Urinary System The kidney ureter bladder urethra
  • 9. The Urinary System The kidney ureter bladder urethra dorsal aorta
  • 10. The Urinary System The kidney ureter bladder urethra dorsal aorta inferior vena cava
  • 11. The Urinary System The kidney ureter bladder urethra dorsal aorta inferior vena cava renal vein
  • 12. The Urinary System The kidney ureter bladder urethra dorsal aorta inferior vena cava renal vein with renal artery behind
  • 13. The Urinary System The kidney ureter bladder urethra dorsal aorta inferior vena cava renal vein with renal artery behind adrenal gland
  • 14. Kidney function <ul><li>Each bean-shaped kidney is embedded in a fatty adipose capsule. </li></ul><ul><li>• The kidneys are retroperitoneal, lying against the dorsal body wall in the upper abdomen. </li></ul>
  • 15. Kidney function • An adrenal gland, which is part of the endocrine system, lies on top of each kidney. • Several structures enter or exit the concave surface of the kidney at the renal hilus, including the ureter and the renal vein, which drains into the inferior vena cava.
  • 16. The kidney
  • 17. The kidney ureter
  • 18. The kidney ureter renal pelvis
  • 19. The kidney ureter renal pelvis renal cortex
  • 20. The kidney ureter renal pelvis renal cortex renal medulla
  • 21. The kidney ureter renal pelvis renal cortex renal medulla pyramids
  • 22. Kidney blood supply
  • 23. Kidney blood supply • When the renal vein is removed and the kidney is shown in frontal section, you can see the deeper renal artery and its connection to the abdominal aorta.
  • 24. Kidney blood supply • Together, these vessels provide the kidneys with a rich blood supply under high pressure that allows them to continuously filter and cleanse the blood.
