This decrease of pressure in the thoracic cavity relative to the environment makes the cavity pressure less than the atmospheric pressure. This pressure gradient between the atmosphere and the thoracic cavity allows air to rush into the lungs; inhalation occurs. The resulting increase in volume is largely attributed to an increase in alveolar space because the bronchioles and bronchi are stiff structures that do not change in size.
There’s proteins (muscle) lipid (fat) calcium )bones) and carbohydrates (mostly for energy)
It will be reactivated during the next cell division.
I think it would be crust
