Pulmonary trunk
![Page 5: Special Circulations: Pulmonary Rt. ventricle Pulmonary trunk.](https://reader038.fdocuments.us/reader038/viewer/2022110206/56649d005503460f949d1772/html5/thumbnails/5.jpg)
Pulmonary arteries (R & L )
Pulmonary arteries appear blue because they are leaving the
heart and traveling to the lungs to become
oxygenated
![Page 6: Special Circulations: Pulmonary Rt. ventricle Pulmonary trunk.](https://reader038.fdocuments.us/reader038/viewer/2022110206/56649d005503460f949d1772/html5/thumbnails/6.jpg)
Lobar arteries
Lobar arteries in the lungs appear blue because they are carrying blood away from the heart to the lungs to become oxygenated
![Page 7: Special Circulations: Pulmonary Rt. ventricle Pulmonary trunk.](https://reader038.fdocuments.us/reader038/viewer/2022110206/56649d005503460f949d1772/html5/thumbnails/7.jpg)
Lobar veins
Lobar veins are traveling to the heart carrying oxygen rich blood that was picked up in the lungs, so they appear red.

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

Special Circulations: Hepatic Portal System
Directs blood from the gastrointestinal tract to liver
![Page 11: Special Circulations: Pulmonary Rt. ventricle Pulmonary trunk.](https://reader038.fdocuments.us/reader038/viewer/2022110206/56649d005503460f949d1772/html5/thumbnails/11.jpg)
Hepatic portal vein
Takes blood from intestines and drains into the liver
![Page 12: Special Circulations: Pulmonary Rt. ventricle Pulmonary trunk.](https://reader038.fdocuments.us/reader038/viewer/2022110206/56649d005503460f949d1772/html5/thumbnails/12.jpg)
Gastric vein (R & L)L
R
Drains the blood from the stomach directly into the hepatic portal vein
![Page 13: Special Circulations: Pulmonary Rt. ventricle Pulmonary trunk.](https://reader038.fdocuments.us/reader038/viewer/2022110206/56649d005503460f949d1772/html5/thumbnails/13.jpg)
Superior mesenteric vein
Drains blood from small and large intestines directly into the hepatic portal vein
![Page 14: Special Circulations: Pulmonary Rt. ventricle Pulmonary trunk.](https://reader038.fdocuments.us/reader038/viewer/2022110206/56649d005503460f949d1772/html5/thumbnails/14.jpg)
Inferior mesenteric vein
Drains into splenic and then into hepatic portal vein
![Page 15: Special Circulations: Pulmonary Rt. ventricle Pulmonary trunk.](https://reader038.fdocuments.us/reader038/viewer/2022110206/56649d005503460f949d1772/html5/thumbnails/15.jpg)
Splenic vein
Drains blood from spleen, pancreas, and part of the stomach into the hepatic portal vein
![Page 16: Special Circulations: Pulmonary Rt. ventricle Pulmonary trunk.](https://reader038.fdocuments.us/reader038/viewer/2022110206/56649d005503460f949d1772/html5/thumbnails/16.jpg)
Hepatic vein
Takes blood from liver and drains into inferior vena cava and then into the heart
