The extensibility of 19 arteries in 60 adults (30 males, 30 females) from 20 to 80 years old were measured and examined. The extensibility was higher for arteries at bending positions such as A. poplitea, A. femoralis, A. carotis comm. and A. axillaris, and at unfixed positions such as A. mesenterica sup. et inf, and A. ovarica ; it was lower for arteries which accompanied bone such as A. subclavia, A. tibialis ant. et post., A. ulnaris and A. radialis. Generally, the elongation, as a function of increased load, showed the S-shaped curve described by Roy et al., but the relationship was linear for some arteries such as A. iliaca comm. et ext., Truncus brachio-cephalicus, A. axillaris, A. carotis int. et ext. (female) . Extensibility was the greatest at ages in the twenties, decreased with age, and was smallest at ages in the seventies. These characteristics were exhibited by the arteries having high extensibility and at high load, but, as exceptions, a tendency to decrease began to appear in the sixties for A. renalis and A. ovarica. The median values of extensibility decrease occurred at the lower ages for A. carotis comm. (female) and A. mesenterica sup. et inf. (male), and at the higher ages for Tr. brachio-cephalicus, A. subclavia, A. radialis, A. tibialis ant. et post., A. testicularis A. poplitea (female), A. axillaris (female) and A. ulnaris (female) . The median values generally occurred at a later age in females than in males.
