The aorta is the largest artery in the human body, responsible for transporting oxygen-rich blood from the left ventricle of the heart to the rest of the body. It plays a critical role in systemic circulation by distributing blood through its various branches.
left ventricle: The chamber of the heart that pumps oxygenated blood into the aorta.
systemic circulation: The part of cardiovascular circulation which carries oxygenated blood away from the heart to the body, and returns deoxygenated blood back to the heart.
artery: A blood vessel that carries blood away from the heart to various parts of the body.
