how are lungs designed in human beings to maximise the area for exchange of gases?

the alveolies in the lungs maximise d area 4 exchange of gases.

4 further reference  u can see s.chand bio book.

The air from the atmosphere reaches the lung by travelling thru nose, trachea n bronchi. Ther r two bronchi going into d two lungs. These bronchi r further divided into many smalls bronchioles. The bronchioles end with a round balloon lyk structure called alveoli. Here the exchange of gases takes place.The alveoli are connected with millions of arteries n veins. The alveoli being spherical in shape require less volume but have more surface area hence increasing the area of exchange of gases.

Hope dis helps.

There are about 1.2-1.3 million alveoli air pouches i.e., surrounded by blood capillaries inside the lungs which abruptly increases the surface area of the gaseous exchange during breathing. Hence, it maximise the area for exchange of of gases.

Lungs are designed to maximise the surface because the have a ballon like structure called alovoli they maximise the surface area helps in easy eschanging of gases.

In the lungs, the air passage (wind pipe) divides into smaller tubes, called bronchi in turn form bronchioles. The bronchioles which terminate in balloon like structures, are called alveoli. Each lung contains 300 350 million alveoli. The alveoli present in the lungs provide maximum surface for exchange of gases. The alveoli have very thin walls and contain an extensive network of blood vessels to facilitate exchange of gases.

lungs contain alveolar sacs which can increase its surface area

alveoli contains a fine network of blood cappilaries. it has balloon like structure.this helps in making the larger area for exchange of gases

the bronchioles in lungs helps in making the larger area for exchange of gases
