Episode notes
Asthma vs COPD Mechanism
- Asthma involves reversible bronchospasm due to airway muscle constriction.
- COPD causes chronic airway obstruction through inflammation, making it irreversible.
Bronchoconstriction Site & Drug Target
- Bronchoconstriction happens mostly in the small bronchioles with muscle tissue.
- Salbutamol targets these deeper lung airways to relieve constriction.
Adrenaline's Role in Airways
- Adrenaline extracted from adrenal glands causes airway dilation and blood vessel constriction.
- This mirrors the sympathetic "fight or flight" response preparing body for action.
