Regional arterial stress-strain distributions referenced to the zero-stress state in the rat

16 male Wistar rats (isolated segments of the thoracic aorta, abdominal aorta, left common carotid artery, left femoral artery, and the left pulmonary artery)

Distension experiment applying pressures to the arterial segments

Comparison between the five different arterial segments
