Humans benefit greatly from the work of Pulmonary surfactant which reduces the surface tension in the alveoli of the lungs. This reduction in alveolar surface tension prevents the alveoli from collapsing and thus causing suffocation.
a hydrogen in the air that is harmful to the lungs

The function of residual volume is to keep enough pressure in the lungs to keep them from collapsing.
To stop air from entering the chest cavity and collapsing the lungs.
there is an equal opposing tendency of the chest wall to expand
The deliberate collapsing of a lung during thoracic operations to facilitate surgical procedure by absence of movement.
backward movement of epiglotis
surfactant- the substance that your lungs produces. Also continuous pressure from the air in there.
The lungs are protected from external or outside damage by the rib cage.
