ANATOMY AND CLINICAL SIGNIFICANCE OF THE ABDOMINAL AORTA IN HUMAN CIRCULATION

The abdominal aorta is the largest artery in the abdominal region and a crucial component of the systemic circulatory system. It is responsible for supplying oxygenated blood to vital abdominal organs and lower body structures. This study examines the anatomical structure and clinical significance of the abdominal aorta, with emphasis on its branching pattern, physiological role, and associated pathological conditions. The abdominal aorta gives rise to major visceral and parietal branches that ensure efficient blood distribution to organs such as the liver, kidneys, intestines, and abdominal wall. Clinically, it is highly significant due to its susceptibility to life-threatening conditions such as abdominal aortic aneurysm and atherosclerosis. Understanding its morphology is essential for diagnosis, imaging, and surgical intervention in vascular diseases.
