Q

Why is the formation of scar tissue bad?

A

Thicker and less elastic than normal tissue of the lungs.
Increses the difussion pathway- reduced rate of diffussion of gases
Leads to higher ventilation rate
Less elastic- cant recoil and expand as much
Vollume of lungs reduced
Reduced tidal volume
Reduced FVC
FEV

Q

Why is the inflamtaion of the bronchi bad?

A

Constricts airways through narrowing thier diameter
Reduced air flow in and out of lungs
Less flow of oxygen/ CO2
FEV reduced
Reduced rate of gas exchange in the alveoli- less ox in blood- cells receive less- reduced rate of respiration ATP production- less energy
