aorta
Sign in to saveAlso known as main artery
The aorta ( ; : aortas or aortae) is the main and largest artery in the human body, originating from the left ventricle of the heart, branching upwards immediately after, and extending down to the abdomen, where it splits at the aortic bifurcation into two smaller arteries (the common iliac arteries). The aorta distributes oxygenated blood to all parts of the body through the systemic circulation.
The aorta is the largest artery in your body, starting from your heart and branching throughout your torso before splitting into smaller arteries in your abdomen. It carries oxygen-rich blood from your heart to every part of your body, making it essential for delivering the oxygen your tissues need to survive.
