Definitions:

Skin And Lungs

Primary organs in animals for protective barrier and gas exchange, respectively; skin acts as a shield against environmental hazards while lungs facilitate oxygen intake and carbon dioxide expulsion.

Alveolar Walls

Thin layers of tissue that form the structure of alveoli, the tiny air sacs in the lungs where gas exchange between the air and blood takes place.

Emphysema

A long-term, progressive disease of the lungs that primarily causes shortness of breath due to over-inflation of the air sacs.

Oxygen Content

The proportion of oxygen present within a given environment, medium, or organism, which is crucial for metabolic processes and respiration.
