Answer:In humans, a pair of lungs are designed in such a way that they are lined by a thin membrane, the smaller tubes called bronchioles a balloon-like structure called alveoli and network of blood capillaries increase the surface area for exchange of gasses

Answer:
The Humans Lungs are designed in this way :
- In humans, air is taken into the body through nostrils.
- During this, air is filtered with the help of hairs in the passage of nostrils.
- Th passage is also lined with mucous, which helps with the same filtration.
- Then, the air passes through throat, and then in the lungs through trachea.
- Now, after the it passed from the trachea, it gets divided into two tubes called the bronchi.
- The bronchi further gets divided into bronchioles.
- The bronchioles consists of balloon like structures that we called alveoli.
- The alveoli are responsible for the increase of surface area in the lungs.
- The alveoli are connected with blood vessels, hence, it is easy for the exchange of gases.
- After, the the gaseous exchange in the aur takes place, the air gets back to the environment through the same passage.
- This is how lungs are designed.
⇒ The balloon like structures designed at the end of the bronchioles is responsible for the increase in surface area which makes the exchange of gases easy and fast.
