1. There is a rich blood supply to the lungs.
2. The inside surface of the lungs is small, and the dose is concentrated in that area.

Rationale 1: The respiratory system offers a rapid and efficient mechanism for delivering drugs. The enormous surface area of the bronchioles and alveoli and the rich blood supply to these areas result in an almost instantaneous onset of action for inhaled substances.
Rationale 2:The inside surface of the lungs is small, and the dose is concentrated in that area is incorrect because the surface area of bronchioles and alveoli in the lungs is a large area.
Rationale 3: The respiratory system offers a rapid and efficient mechanism for delivering drugs. The enormous surface area of the bronchioles and alveoli and the rich blood supply to these areas result in an almost instantaneous onset of action for inhaled substances.
Rationale 4:Inhaled medications are given at very high doses is incorrect because inhaled medications are given at lower doses than if taken systemically.
Rationale 5:Inhaled medications are given with food is incorrect because the absorption of inhaled medication is not affected by the intake of food.
Global Rationale: The respiratory system offers a rapid and efficient mechanism for delivering drugs. The enormous surface area of the bronchioles and alveoli and the rich blood supply to these areas result in an almost instantaneous onset of action for inhaled substances.
