Circulation of GI system (arteries and veins etc)

Question 1

what arteries supply foregut, midgut and hindgut?

Answer 1

1) Foregut= Celiac trunk =>SLC
2) Midgut= Superior mesenteric =>MRI
3) Hindgut = Inferior mesenteric =>LeSS

Question 2

What does the Superior mesenteric artery supply ?
where does it arise from ?
(4)

Answer 2

• Arises from the posterior neck of pancreas

- Supplies the SI, ascending colon + 2/3 of transverse colon

Question 3

2- Descending colon
3-Sigmoid colon
4- Rectum

Question 4

Answer 4

1) Stomach
2) Liver
3) Pancreas
4) Spleen
5) First part of duodenum

Question 5

3

Answer 5

Middle colic artery
Right colic artery
Illeocollic artery

Question 6

Branches of the inferior mesenteric artery
(3)
LeSS
le sigsure

Answer 6

Left Colic Artery
Sigmoid Artery
Superior Rectal artery

Question 7

Coelliac trunk branches

CSL

Answer 7

1) Common hepatic artery
2) Splenic artery
3) Left gastric artery

Question 8

Abdominal aorta branches
CSI
branches

Answer 8

T12 => through the diaphagram = inferior phrenic
- Coelliac trunk ( splenic , left gastric , common hepatic artery)
L1= Superior mesenteric : Jejunal arteries, Illeal arteries, inferior pancreaticoduodenal, Middle colic and right Collic , = loop is completed by illeocollic artery
L2= renal arteries = inferior suprarenal and gonadal arteries
L3=Inferior mesenteric = L. colic artery, Sigmoid branches, Superior rectal artery
L4= paired lumbar arteries , bifurcation of aorta to become the common iliac arteries

Question 9

Blood Supply to the stomach

Answer 9

Splenic artery splits into 2 and supplies the stomach
=> short gastric arteries
=> left gastroepiploic ,

Question 10

Branches of the common hepatic artery

PGR

Answer 10

1-Proper hepatic
2-Gastroduodenal —>Right gastroepiploic and Superior pancreatic duodenal
3-Right Gastric

Question 11

where does
a) the vena cava perforate the diaphragm 
b) oesophagus 
c)Aortic hiatus 
(3)

Answer 11

Remember
T8 = 8 letters= VENA CAVA
T10= 10 Letters= OESOPHAGUS
T12=12 Letters= AORTIC HIATUS

Question 12

blood supply to the omentum

Answer 12

gastroepiploic artery
