Presentation Transcript

  1. Special Circulations

  2. Special Circulations: Pulmonary

  3. Rt. ventricle

  4. Pulmonary trunk

  5. Pulmonary arteries (R & L ) Pulmonary arteries appear blue because they are leaving the heart and traveling to the lungs to become oxygenated

  6. Lobar arteries Lobar arteries in the lungs appear blue because they are carrying blood away from the heart to the lungs to become oxygenated

  7. Lobar veins Lobar veins are traveling to the heart carrying oxygen rich blood that was picked up in the lungs, so they appear red.

  8. Pulmonary veins (R & L) Pulmonary veins appear red because oxygen rich blood is returning from the lungs and entering the heart

  9. Left atrium

  10. Special Circulations: Hepatic Portal System Directs blood from the gastrointestinal tract to liver

  11. Hepatic portal vein Takes blood from intestines and drains into the liver

  12. Gastric vein (R & L) L Drains the blood from the stomach directly into the hepatic portal vein R

  13. Superior mesenteric vein Drains blood from small and large intestines directly into the hepatic portal vein

  14. Inferior mesenteric vein Drains into splenic and then into hepatic portal vein

  15. Splenic vein Drains blood from spleen, pancreas, and part of the stomach into the hepatic portal vein

  16. Hepatic vein Takes blood from liver and drains into inferior vena cava and then into the heart

  17. Inferior vena cava

  18. Special Circulations: Cerebral

  19. Internal carotid a. (R/L)

  20. Anterior cerebral a. (R/L)

  21. Anterior Communicating a.

  22. Middle cerebral a.

  23. Posterior Communicating a.

  24. Posterior cerebral a.

  25. Basilar a.

  26. Vertebral a. (R/L)
