Both assertion and reason are true, but the reason is not the correct explanation of assertion because:
- Human lungs are formed of millions of sac-like structures called alveoli.
- Alveoli have very thin walls which help in exchange of gasses at their surface.
- Alveoli are made up of simple squamous epithelial tissue.
- Alveoli are rich in blood vessels that bring deoxygenated blood towards lungs and carry oxygenated blood from lungs to all other body tissues.
