Vessels and Shit Flashcards
What are the three divisions of the celiac trunk?
- Left gastric
- Splenic
- Common Hepatic
What does the splenic artery branch into and supply?
- goes to hilum of spleen, supplies spleen
- short gastric branches to supply fundus of stomach
- L gastro-epiploic branches to supply greater curvature
- pancreatic branches to supply body and tail of pancreas
What does the Proper Hepatic Artery divide into? Where does it go?
R/L hepatic artery, and enters porta hepatis.
What level does the SMA arise?
L1
What are the 6 branches from the SMA?
- Ilieocolic
- Middle Colic
- Right Colic

- Intestinal Branches
- Inferior Pancreaticoduodenal
Does jejunum or ileum have more arcades?
ileum
Does the jejunum or the ileum have longer vasa recta?
jejunum
The SMV joins what to form what?
Joins splenic vein to form portal vein
At what levels does the IMA form?
L3.
What are the branches of the IMA?
- left colic
- sigmoidal
- superior rectal
What makes the marginal artery? Why is it important?
Anastomoses between the middle, left and right colic arteries form the marginal artery. It is important because all of the colic arteries are connected and blood can circulate even if one of the arteries is obstructed.
Explain the route blood travels to get from the superior rectal vein to get into the Portal Vein.
superior rectal > becomes IMV > splenic > joins SMV to become the portal vein.
What is the teniae coli? What does it form?
The longitudinal bands that are 1/6 shorter than the colon. It forms sacculations (haustra).
What do you call the fat collections on the colon?
