The lungs in human beings contain 480 million alveoli with 0.2-0.5 mm diameter located at the end of the airways. In this way, it is used to maximize the area for gas exchange. In order to enhance gas exchange in the lungs, the alveoli, which are tiny, rounded or balloon-like structures at the ends of the bronchioles, increase surface area.

Maximization of Area for Exchange of Gases
- An essential part of the respiratory system are the lungs.
- The pleura is a thin membrane sac that surrounds the lungs, which are soft, elastic, spongy organs.
- Bronchioles are formed when the bronchi of the lungs are further split.
- The alveoli are sacs that range in size from 0.2 to 0.5 mm.
- These alveoli are found at the tip of the airways of the lungs.
- It’s possible to compare alveolar structure to the appearance of raspberries or grape.
- There are roughly 480 million alveoli in a typical adult lung.
Summary:
How are the lungs designed in human beings to maximize the area for exchange of gases?
At the end of the airways of a human’s lungs are 480 million alveoli that range in size from 0.2 to 0.5 mm. It is utilised in this manner to increase the area for gas exchange. Lungs are the important part of respiratory system which contain alveoli which helps in human respiration.
