Question
What is the reason for the lungs to lose elasticity?
✓
Answer
The elastin present in the Songs gives its elastic nature.
People with emphysema and bronchitis have difficulty in exhaling because the enzyme elastase destroys the elastin around the alveoli and reduces the elasticity of the lungs.
