Abdominal Aorta

The Abdominal Aorta (pronounced: ab-DOM-uh-nuhl ao-RTA) is the largest artery in the abdominal cavity that carries oxygenated blood from the heart to the organs and tissues of the abdomen.

Etymology

The term "Abdominal Aorta" is derived from the Latin words "abdomen" meaning belly and "aorta" meaning the main artery.

Anatomy

The Abdominal Aorta begins at the diaphragm, splitting off from the Thoracic Aorta, and extends to the lower part of the abdomen where it splits into the two Common Iliac Arteries. It supplies blood to the organs and tissues of the abdomen, including the stomach, liver, spleen, kidneys, and intestines.
