The aorta is the largest artery in the human body.
Understanding Artery Size
Determining which artery is "bigger" requires clarification. Size can refer to diameter, length, or even blood volume carried. The aorta, at roughly 10 to 25 millimeters in diameter, surpasses other arteries in terms of diameter.

Several studies also show variations in artery size. For example, the radial artery is consistently larger than the ulnar artery in both arms. The Radial Artery is Larger than the Ulnar The radial artery is larger than the ulnar
Therefore, the context matters. While the aorta holds the title of the largest artery overall in terms of diameter, other arteries can be considered large based on their specific anatomical location and functional significance. The term "large artery" itself is used to refer to a group of arteries crucial in overall systemic circulation, including the aorta and others vulnerable to atherosclerosis.
