What vessels are responsible for abdomino-pelvic drainage?
- caudal vena cava
- portal vein
What veins drain into the caudal vena cava?
- common iliac veins (internal and external iliac veins)
- deep circumflex iliac veins
- lumbar veins (dorsally)
- ovarian or testicular veins (gonadal veins)

The portal vein drains what organs?
- spleen

- large intestine
How are organs drained via the portal vein?
blood from organs enters the liver via portal vein and then using the heptic veins it connects to the caudal vena cava
What veins drain into the portal vein?
- gastroduodenal vein
- splenic vein
- cranial mesenteric vein
- caudal mesenteric vein
What vein drains the right lobe of pancreas, duodenum, right side of stomach, and right side of greater omentum?
gastroduodenal vein
What vein drains the spleen, left side of stomach, left lobe of pancreas, and left side of greater omentum?
splenic vein
What vein drains the ileum, jejunum, right lobe of pancreas, and caudal portion of duodenum?
cranial mesenteric vein
What vein drains the cecum and colon?
caudal mesenteric vein
Blood flow to the liver occurs on what surface of the liver?
Visceral surface
Blood flow to the liver is by what vessels?
- hepatic artery (blood supply for organ)
- portal vein (processing from other organs)
Blood flow away from the liver occurs on what surface of the liver?
parietal surface
Blood flow away from the liver is by what vessels?
hepatic veins (processed blood returns to blood flow)
