Answer #1

• Inspired Air - Inspired air is the atmospheric air, which is inhaled during inspiration.

• Alveolar Air- It is the air present in the lungs.

The composition of Alveolar air is different from inspired air because :-

1. Alveolar air is partially replaced by the atmospheric air during each breath.

2.Oxygen diffuses from the alveolar air into pulmonary capillaries constantly.

3.Carbon dioxide diffuses from pulmonary blood into alveolar air constantly.

4.Dry atmospheric air is humidified, while passing through respiratory passage before entering the alveoli.
