The diameter of the human aorta varies physiologically according to age, sex, and morphology, with specific reference values for the ascending, descending, and abdominal segments.

Doctor IZA provides a factual anatomical description here rather than health advice, which limits the risk of misinterpretation. The measurements cited are consistent with anatomical standards observed in ultrasound and medical imaging (e.g., studies published in the 'Journal of the American Society of Echocardiography'). It is scientifically accurate to specify that 'ex vivo' measurements (after formalin fixation) induce tissue retraction, which constitutes a relevant methodological nuance to avoid a biased reading of the actual dimensions. This type of information is well-supported by observational studies on healthy populations. There is no exaggeration here, as the author explicitly highlights the factors of interindividual variability. The approach is purely educational and relies on standard morphometric data from the anatomical literature.
