what are the 3 branches of the celiac artery

what is the artery that branches off of the celiac and goes to the stomach?
left gastric a
what are the 3 branches of the splenic artery
- Left gastromental (gastroepiploic) artery
- Short gastric arteries
- Pancreatic branche
where does the Left gastromental (gastroepiploic) artery of the splenic artery go to/supply
to the left side of great gastric curvature and great omentum
where does the Short gastric arteries of the splenic artery go to/supply
to the fundus of the stomach
where does the Pancreatic branches of the splenic artery
To the left lobe of pancreas
what procedure is this
Total Splenectomy
what procedure is this
Partial Splenectomy
what type of tissue is the spleen
lymphoid tissue
what would happen if you did not ligate the splenic artery as close to the spleen as possible
you would lose the splenic artery which will cause blood loss to the stomach and pancreas
**remember splenic a. has 3 main divisions
The left gastric artery divides into __________ branches
Esophageal branches (To the caudal most part of
esophagus)
where is the left gastric artery located
lesser curvature
how many arteries does the hepatic artery divide into
- Hepatic branches
- Right gastric artery
- Gastroduodenal artery
what does the Gastroduodenal artery divide into
- Right gastromental
(gastroepiploic) artery - Cranial pancreaticoduodenal
artery
what does the hepatic branches of the hepatic artery supply/go to
To liver
Cystic artery
Right gastric artery supplies/goes to the
To right side of lesser curvature of stomach and lesser omentum
Right gastromental (gastroepiploic) artery supplies/goes to
To right side of the greater curvature of stomach and greater omentum
Cranial pancreaticoduodenal
artery goes to/ supplies
To duodenum and pancreatic
right lobe
Celiac artery in summary supplies
Cranial Mesenteric artery has how many branches? List them.
- Ileocolic artery
- Caudal pancreaticoduodenal artery
- Jejunal arteries
- Ileal arteries
Ileocolic artery splits into how many arteries
A. Colic branch
B. Right colic artery
C. Middle colic artery
D. Cecal artery
F. Ileal branches (mesenteric)
Colic branch supplies/goes to
To initial part of ascending colon
Right colic artery supplies/goes to
To distal ascending colon, right colic flexure, initial
transverse colon
Middle colic artery goes to/supplies
to distal transverse colon, left colic flexure, initial descending colon
Cecal artery does to/supplies
cecum
Antimesenteric ileal branch is from what artery?
what does it supply?
branch off of the cecal artery
supplies the ileum
Cranial Mesenteric artery has how many main branches
- Caudal pancreaticoduodenal artery
- Jejunal arteries
- Ileal arteries
what does the Caudal pancreaticoduodenal artery supply/go to
(to distal descending duodenum and adjacent right lobe of pancreas
what procedure is this
Enterotomy
what procedure is this
Enterotomy and enteroanastomosis
Cranial Mesenteric artery in summary supplies
Caudal Mesenteric artery divides into what 2 main divisions
- Left colic
- Cranial rectal artery
what does the left colic artery supply/go to
To descending colon
what does the Cranial rectal artery supply/go to
- (To cranial part of rectum
what 2 things participate in Abdomino-pelvic drainage
- Caudal Vena Cava
- Portal Vein
what specifically does the caudal vena cava drain
limb, tail, back, organs
what specifically does the portal vein drain
digestive system
accessory gland
pancreas
what veins drain INTO the caudal vena cava (7)
- Common iliac veins
- Deep circumflex iliac veins
- Lumbar veins (Dorsally)
- Gonadal (ovarian or testicular veins)
- Renal veins
- Phrenicoabdominal veins
- Hepatic veins
what veins comprise the common iliac veins
- Internal iliac veins
- External iliac veins
what does the left testicular/ovarian vein drain into
renal vein
identify 1, 2, 3
- Caudal vena cava
- Azygos v
- Common iliac vv
Portal vein drain:
spleen, pancreas, stomach, small and large intestines.
spleen, pancreas, stomach, small and large intestines are drained via portal vein, the blood enter the _____ and then using the ______veins connects with the caudal vena cava
live, hepatic
identify 1 and 2
- Portal vein
- Hepatic veins
Portal Vein divides into 4 veins
list them
- Gastroduodenal vein
- Splenic vein
- Cranial mesenteric vein
- Caudal mesenteric vein
what vein drains the pancreas [right], duodenum, stomach [right]and greater omentum [right])
Gastroduodenal vein
what vein drains spleen, stomach [left], pancreas [left], greater omentum [left])
Splenic vein
what vein drains ileum, jejunum, pancreas [right], duodenum (caudal)
Cranial mesenteric vein
what vein drains cecum and colon
Caudal mesenteric vein
does the rectum drain directly to the caudal vena cava
YES
why do we need the blood of the spleen, pancreas, stomach, sm/large intestine to go the liver before caudal vena cava
ensure we get stuff out of the blood that is necessary or that needs eliminated
ex: drugs
what vein is A, B
A: portal vein
B: vena cava
Blood flow TO the liver
- Hepatic artery–Blood supply
- Portal vein–Processing
Blood flow FROM the liver
Hepatic veins
* Processed blood return to blood flow
