Blood supply Flashcards
Which arteries supply the abdominal wall? (4)
Cranial abdominal Deep external iliac Cranial epigastric (and cranial superficial epigastric) Caudal epigastric (and caudal superficial epigastric)
The abdominal organs are supplied by arteries that branch off which major blood vessel?
Aorta
Which blood vessel supplies the cranial abdominal organs?
Caeliac artery
What are the 3 main branches of the caeliac artery?
Hepatic
Left gastric
Splenic
Which blood vessel supplies the mid abdominal organs?
Cranial mesenteric
What are the 3 main artery branches of the cranial mesenteric artery?
Ileocoli
Caudal pancreaticoduodenal
Jejunal
What blood vessel supplies the caudal abdominal organs?
Caudal mesenteric
What are the 2 main branches of the caudal mesenteric artery?
Left colic
Cranial rectal
Which blood vessels supply the kidneys?
Left and right renal arteries
Which blood vessels supply the ovaries/testicles?
Left and right ovarian/testicular arteries
What is an anastomoses? What is its purpose?
Connection between blood vessels
Safety mechanism - if one vessel is occluded, the organ can still receive blood supply via another route
Which blood vessel do all GI organs (some exceptions) drain via? Why?
Hepatic portal vein
Liver can metabolise/detoxify hazardous substances
Where does the hepatic portal vein drain into?
Caudal vena cava
Do the hepatic veins drain into the hepatic portal vein?
No
Directly into caudal vena cava
Which vein does the left gastric drain into?
Splenic
Not hepatic portal
Almost all GI organs drain via hepatic portal vein. Which organs are the exceptions?
Liver - hepatic veins drain into caudal VC
Stomach - left gastric drains into splenic vein
Which artery does not have a vein of the same name?
Caeliac artery
No caeliac vein
Which blood vessels are the terminal veins of the hepatic portal vein?
Cranial and caudal mesenterics
What is different about the blood supply to the left testicle?
Left testicular vein drains into left renal vein
NOT caudal VC
