2. splenic artery - spleen, pancreas, stomach
3. common hepatic artery - gall bladder, duodenum, pancrease, liver, stomach

Front 8

what does the left gastric artery branch off to

Back 8

1. esophageal branch
2. gastric branch

Front 9

what does the splenic artery branch off to

Back 9

1. pancreatic branch
2. short gastric branch
3. left gastroepiploic branch

Front 10

Back 11

a branch of the right hepatic artery

Front 12

what does the superior mesenteric artery vascularize

Back 12

duodeum, jejunum, ileum, Cecum,
Appendix, Transverse colon, Pancreas, Ascending Colon
*small intestine parts, cat, pac

Front 13

what are the main branches of the superior mesenteric arteries

Back 13

1. inferior pancreaticoduodenal
2. intestinal branches (jujunal or ileal)
3. Ileocolic artery - supplies cecum, ileum, appendix
4. middle colic - supplies transverse colon
5. right colic - supplies ascending colon

Front 14

what type of arteries extend from the cecum to the colon

Back 14

mariginal arteries - an anastomic channel which links the arteries of the superior and inferior mesenteric arteries.

****important for collateral circulation

Front 15

what does the inferior mesenteric artery vascularize

Back 15

sigmoid colon, upper rectum, transverse colon, descending colon

**sutd

Front 16

what are the branches of the inferior mesenteric artery and what does each vascularize

Back 16

1. left colic artery - transverse and descending colon
2. sigmoidal branches - sigmoid colon
3. superior rectal artery - superior part of rectum

Front 17

what 2 arteries supply blood to the rectum

Back 17

1. superior rectal artery
2. internal iliac artery

Front 18

what 2 ways can venous blood be drained

Back 18

via the hepatic portal vein or the inferior vena cava

Front 19

characteristics of hepatic portal vein
1. formed by...
2. what drains INTO THIS vein
3. what does this vein DRAIN INTO

Back 19

1. formed by union of splenic and superior mesenteric VEINS.
2. Things that drain INTO hepatic portal vein:
- digestive tract and associated glands
- LEFT and RIGHT gastric veins (actually one continuous loop - collateral circulation)

3. the hepatic portal vein DRAINS into the liver which then drains into the inferior vena cava

Front 20

what drains into the splenic vein which contributes to the hepatic portal vein

Back 20

inferior mesenteric vein

**shows collateral venous circulation

Front 21

what drains into the inferior vena cava

Back 21

-blood from the abdominal wall and the liver

-R/L external and internal iliac veins DRAIN INTO R/L common iliac veins which DRAIN INTO inferior vena cava

Front 22

which veins drain directly into the inferior vena cava

Back 22

1. right and left RENAL veins
2. right and left HEPATIC veins
3. right SUPRARENAL vein
4. right GONADAL vein

**left suprarenal and left gonadal vein flow blood into the left RENAL vein which then goes to IVC

Front 23

explain the esophagus example of how portal and systemic anastomosis works

Back 23

allows blood to reach the heart in alternative pathways if something like a blockage occurs

- esophagus example
-esophageal vein can drain into AZYGOUS (drains into IVC) or drain into LEFT GASTRIC VEIN (drains into portal vein)

***these esophageal veins are connected through anastomoses

Front 24

name 2 other portal-systemic anastomosis examples

Back 24
