how are the lungs designed in human being to maximise the area for exchange of gases
Answers
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 gases.
Explanation:
••••the exchange of gases takes place between the blood capillaries that surround the alvali and the gases present in the avoli
••••thus alvoli are the site for exchange of gases
••••the lungs get filled up with air during the process of Inhdution as rids are listed up cliaphragm is flatted
••••each lung contains 300-350 million alveoli
••••these numerous alvoli increase the surface area for gaseous exchange making the process of respiration more efficient
