BREATHING and EXCHANGE OF GASES
278064
Which one of the following four organs of respiratory system is correctly matched with its characteristics?
1 Nose - Two branches of the trachea that brings air into the lungs.
2 Trachea - Small flap that prevents food from entering
3 Diaphragm - Dome shaped muscle that pushes on the lungs during exhalation.
4 Alveoli - Pair of organs that inflate as you inhale and deflate as you exhale.
Explanation:
(c) Trachea (also called windpipe) is a tube that connects the pharynx and larynx to the lungs, allowing the passage of air, and so is present in all air-breathing animals with lungs.
Alveoli - main site of gaseous exchanges.

The given diagram represents the human respiratory system with few structures labelled as I, II, III and IV.
The exchange of gases takes place in which labelled structure ?
1 $1\to $ trachea
2 II$\to $ Bronchi
3 III$\to $ bronchioles
4 IV$\to $ alveoli
Explanation:
(d) In the diagram, label IV represents alveoli. Alveoli are sac like structure present in lungs. They are the site for exchange of gases. The label I represent trachea, label II represents bronchi and label III represents bronchioles.
