The lungs contain approximately 23 generations of airways, starting from the trachea and branching into progressively smaller bronchi and bronchioles. In total, there are about 300,000 to 500,000 individual airways, which include both the large bronchi and the smaller terminal and respiratory bronchioles. These airways facilitate the movement of air in and out of the lungs, leading to the alveoli where gas exchange occurs.
oh, I think.............no. They dont. They only are oxegen poor. your airways and lungs only do.
No, Proventil does not contain steroids. It is a bronchodilator medication that works by opening up the airways in the lungs to make it easier to breathe.
The lungs contain alveoli, bronchioles, and bronchi. Alveoli are tiny air sacs where oxygen is exchanged for carbon dioxide in the blood. Bronchioles are small airways that branch from bronchi, which are larger airways that lead to the lungs.
A lot.
millons of alveoli are in the lungs

Mammals' lungs contain alveoli, which are basically "dead ends", so contain a mixture of fresh and stale air. However, in bird as their airways are open at both ends (one-way) air flows straight through.
