how are the alveoli design to maximize the exchange of gases?
Answers
Answer: within the lungs the passage divided into smaller cubes which finally terminate in ball like structure which are called alveoli alveoli provide a surface where the exchange of gases can take place the walls of alveoli contain any extension network of blood vessels as we have seen in earlier years when we breathe in we lift are waves and flatten a diaphragm and the chest cavity becomes larger as a result because of this there is sucked into the lungs and fills the expanded alveoli
Explanation:
Within the lungs , the air passage
divides into smaller and smaller tubes
called bronchi which in turn form
bronchioles . The bronchioles terminate
in balloon-like structures called alveoli .
The alveoli present in the lungs provide
maximum surface for exchange of gases .
The alveoli have vary thin walls and
contain an extensive network of blood
vessels to facilitate exchange of gases .
