Q.
What happens to the windpipe, or trachea, before it reaches the lungs?
Breathing and Exchange of Gases
Solution:
About half of $13\, cm$ long trachea is inside the chest and the rest is in the neck. The lower end of the trachea divides into two bronchi (tubes) that carry air into the lungs. One bronchus goes to the left lung, the other to the right lung.
