Answer 2

Answer:

A hollow tube that serves as a passage of air into the lungs is known as the trachea (Wind pipe)

Explanation:

• Our respiratory system includes the nose, mouth, throat, voice box, windpipe, and lungs.
• When we inhale the air enters the nostrils and reaches the pharynx.
• At the bottom of the pharynx, the pathway is divided into two, one for food and the other for air.
• There is a small flap called the epiglottis, covers the air-only passage when we swallow.
• Then, the inhaled air reaches the larynx, which is the top of the air-only pipe.
• The larynx is continued to the trachea (windpipe). At the bottom, it is divided into two air tubes called bronchi.
• Then, the bronchi are continued down to our lungs.
