Alveoli are small balloon-like structures present in the millions inside our lungs.
- The gaseous exchange takes place in alveoli.
- The walls of alveoli are very thin and have lots of thin blood capillaries .
- Since they are very small, high in number, they provide a large surface area which maximizes the exchange of gases .
