I think u r confusing the pulmonary compliance with vascular compliance. Compliance means the change is volume per change in pressure.
Now a question, which lung will have more compliance the lung of a healthy new born child or a healthy 50 yr old person...
The answer would be 50 yr old person because as the age increases we loose the elastic fibers, this would decrease the lung recoil & increase the compliance.
Now the age related changes in the arteries are totally different. We have hardening of the arteries with age due to atherosclerosis which makes them less distensible, as a result, decreasing the compliance.
