Document Summary
Situated behind ribs 9,10,11, on the left upper quadrant. Laceration by sharp edges of fractured ribs damages spleen. Can bleed to death if not repaired since highly vascular. Supplies everything in abdomen and branches to lower limb. Abdominal aorta sends paired branches to abdominal walls (posteriorly and anteriorly) and also to paired viscera (e. g. gonads, adrenals, kidneys) Sends unpaired branches to unpaired viscera - all derivatives of embryological primitive gut. e. g. tubular git, spleen, pancreas, git, gall bladder, liver. These three supply all derivatives of primitive gut. Foregut also gives rise to liver, gallbladder, spleen. Midgut gives rise to rest of duodenum to 2/3 proximal end of transverse colon. Coeliac trunk supplies the derivatives of the foregut. For retroperitoneal viscera (pancreas + duodenum) branches sent directly to them. For intraperitoneal viscera the arteries go through mesentery and then to target.
