Which blood vessel sends oxygen rich blood from the heart to the rest of the body?
The primary blood vessel that transports oxygenated blood from the heart is the aorta.
The aorta starts as the ascending aorta from the left ventricle of the heart. It then makes a hairpin bend (called the aortic arch) and becomes the descending aorta. In the thoracic cavity it is known as the thoracic aorta and in the abdominal cavity as the abdominal aorta.
In the abdominal cavity, the aorta branches into two main arteries called the iliac arteries.
All along the path of the aorta, arteries branch off and carry oxygenated blood to various parts of the body.
