Aorta (noun)

The main and largest artery in the human body, originating from the left ventricle of the heart and extending down to the abdomen, where it splits into two smaller arteries.

Examples:

1. The aorta supplies oxygenated blood to the body's vital organs and extremities.

3. An aortic aneurysm is a bulging in the wall of the aorta, which can be life-threatening if it ruptures.
