Lungs: With age, lung function becomes "less efficient." Which one does not explain why?     Lung tissue becomes more "elastic" resulting in less expansion.      There is a decrease in "reserve capacity" that affects stamina.     There is a decrease in the number of airs sacs for oxygen transport.     Muscles in the rib cage become weaker and reduce contraction.
