If the compliance values are normalized on the basis of wall thickness, the compliances of the two vessels become quite similar. Contrary to popular belief, veins are not inherently weaker. Recall that saphenous veins are usually used to replace arteries in coronary revascularization procedures.
Compliance for these vessels can be plotted another way that puts volume (i.e length) on the horizontal axis and pressure (i.e. tension) on the vertical axis like the length-tension diagrams examined earlier (Figure 07).
