Abdominal Aorta
From WikiLectures
The abdominal Aorta supplies oxygenated blood to the abdominal organs and other visceral structures through its branches
Position[edit | edit source]
- It starts posterior to the arcuate ligament at the T12 level from the descending (thoracic) Aorta
- It ends to the left of the mid-line at the L4 level and branches to become the common iliac arteries
