The alveoli is where the oxygen is exchanged in the blood. The reason they are in clusters is to maximize surface area. With emphysema the clusters are flattened and clogged with the tar from the cigarettes which is why they have such a hard time breathing.

How do the structures of the alveoli and capillaries support the function of gas exchange?

Alveoli are found within the lungs. The alveoli act as a specialised gaseous exchange surface in mammals. Another function of alveoli is the production of surfactant.

What does a group of alveoli form?

A group of alveoli forms an alveolar sac, which is a cluster of tiny air sacs in the lungs. These sacs are the primary sites for gas exchange, allowing oxygen to enter the bloodstream and carbon dioxide to be expelled. Each alveolus is surrounded by capillaries, facilitating the transfer of gases between the air in the alveoli and the blood. Together, these structures are crucial for efficient respiratory function.

Why are the alveoli and bronchi separated in the lungs?

The bronchi are the tubes that actually carry the air to the lungs, they have a different function than the alveoli which function in the process for gas exchange.


What is the function of type 2 alveoli walls?

Type 2 alveoli cells secrete surfactant, which helps to reduce surface tension in the alveoli. This allows for easier expansion of the alveoli during inhalation and prevents them from collapsing during exhalation, promoting efficient gas exchange.
