Oxygen diffuses from the inhaled air in the alveoli of the lungs, where its concentration is higher, into
the cytoplasm of red blood cells, where its concentration is lower. Patients diagnosed with
emphysema have damaged alveoli. This results to fewer, larger air spaces instead of many small
ones. Explain how this damage can lead to shortness of breath?
The surface area of lungs is reduced. Hence, less oxygen can diffuse into the red blood
cells.
The surface area of lungs is increased. Hence, more oxygen can diffuse into the red blood
