11 - blood supply of rectum

rectum is supplied mainly by three arteries they are :

a- SUPERIOR RECTAL OR HEMORRHOIDAL ARTERY - which is a branch of the INFERIOR MESENTRIC which arises from the ANTERIOR SURFACE OF THE AORTA .

b-MIDDLE RECTAL OR MIDDLE HEMORRHOIDAL ARTERY - which is a branch of the INFERIOR VESICAL ARTERY which is a branch of the INTERNAL ILIAC ARTERY .

c- INFERIOR RECTAL OR INFERIOR HEMORRHOIDAL ARTERY - which is a branch of the INTERNAL PUDENDAL ARTERY which is a branch of the INTERNAL ILIAC ARTERY.

10 - Blood supply of stomach

The stomach is supplied by many arteries like :

1- short gastric arteries - branches of the splenic artery - supply the fundus of stomach

2-left gastro epiploic artery - branch of the splenic artery - supply the greater curvature of the stomach .

3- left gastric artery which is a direct branch of the coeliac trunk that arises from the aorta . supplies the lesser curvarture.

4- right gastric artery which is a branch of the common hepatic artery - supplies the lesser curvature.

5- right gastro epiploic artery which is a branch of the gastro duodenal artery which is again a branch of the common hepatic artery- supplies the greater curvature

--------------------------------------

The branches of the COELIAC TRUNK are :

1-common hepatic artery

2-left gastric artery

3-splenic artery

--------------------------------------

The branches of splenic artery are:

1-short gastric branches

2-left gastro epiploic artery

--------------------------------------

The branches of the common hepatic artery are :

1-hepatic artery proper

2-right gastric artery

3-gastroduodenal artery

-------------------------------------

The branches of the gastroduodenal artery are :

1-right gastro epiploic artery

2-superior pancreatico duodenal artery

-------------------------------------

P.S: The INFERIOR PANCREATICO DUODENAL ARTERY is a branch OF THE SUPERIOR MESENTRIC ARTERY .
