Which human blood vessel is the largest?
Quick Answer
The aorta is the largest blood vessel in the human body. It carries oxygen-rich blood from the heart to the rest of the body.
The Full Story
The aorta is the body’s largest artery and the main highway for oxygenated blood leaving the heart. In adults, it is about 2.5 to 3 centimetres in diameter where it exits the heart. It distributes blood to all major organs through a branching network of arteries. Because of the pressure it carries, the aorta is a critical vessel in cardiovascular health.
