Answer 2

Structure of lungs

Explanation:

• Lungs play a major role in the respiratory system.
• In humans a pair of lungs are so designed that they are lined by a thin membrane.
• The small tubes called bronchioles , a balloon like structure called alveoli and a network of blood capillaries increase the surface area for gas exchange.
• Lungs are soft spongy and elastic organ enclosed by pleura (a thin membranous sac).
• Alveoli provide a larger surface area to maximize the exchange of gas in the lung.
