Mechanical responses of the femoral and carotid arteries evaluated at their respective in vivo axial stretches. A Pressure–diameter relationships. The diameters are normalized to each corresponding zero-pressure, in vivo axial stretch values (^*P < 0.05). B Local compliance differences assessed at increments of 20 mmHg (^*P < 0.05). C Mean circumferential (hoop stress) and pressure relationships. Means were not found to be significantly different. D Mean axial stress and pressure relationships. Significances between mean axial stresses were found at all pressures
