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.
One celled air sacs are called?
These are the Alveoli.
Where does the actual air exchange take place in the lungs?
The actual air exchange in the lungs takes place in the alveoli, which are tiny sacs at the end of the bronchioles. Oxygen from the inhaled air passes through the walls of the alveoli and into the bloodstream, while carbon dioxide moves from the blood into the alveoli to be exhaled.
The bronchi go directly into the alveoli.?
The bronchi branch into smaller tubes called bronchioles, which then lead to clusters of air sacs called alveoli. The alveoli are the site where oxygen and carbon dioxide exchange occurs during the process of respiration.
What do Type 2 alveolar cells secrete?
Type 2 alveolar cells secrete surfactant, a mixture of lipids and proteins that reduces surface tension in the alveoli, preventing them from collapsing. This helps maintain the elasticity of the alveoli and promotes efficient gas exchange in the lungs.

What are the tiny air sacs called in the bronchi branches?

What are the alveoli and what happens in them?
the alveoli is happen the blood
What are small air sacs of lung tissue called?
