What is the normal diameter range for the abdominal aorta?

The normal diameter range for the abdominal aorta is typically between 2-3 cm in adults. This range is important because it indicates the health and functionality of the aorta, which is the main artery that supplies blood from the heart to the rest of the body. If the diameter of the abdominal aorta exceeds this range, it may indicate conditions such as an aortic aneurysm, which can pose serious health risks. Knowing the normal diameter helps healthcare professionals assess and diagnose vascular conditions effectively. The other options either represent diameters that are too small or too large for a healthy adult aorta, which does not align with established medical standards.
