Mostly oxygenated blood .
branches of abdominal aorta are classified into three. these are : ventral branches, dorsal branches and lateral branches. ventral branch consists of : coeliac artery (at T12 vertebral level ). superior mesenteric artery(at L1 level). inferior mesenteric artery(at L3 level). dorsal branch consists of : right and left lumbar arteries. median sacral artery. lateral branches consists : right and left inferior phrenic arteries. right and left suprarenal arteries. right and left renal arteries. right and left gonadal arterries. terminal branches are right and left common illiac arteries.
The aorta is usually divided into five segments/sections:Ascending aorta: the section between the heart and the arch of aortaArch of aorta-the peak part that looks somewhat like an inverted "U"Descending aorta-the section from the arch of aorta to the point where it divides into the common iliac arteriesThoracic aorta-the half of the descending aorta above the diaphragmAbdominal aorta-the half of the descending aorta below the diaphragm
