Final answer:
The trachea, also known as the windpipe, is the correct answer as it is the long tube that directs inhaled air from the larynx to the lungs before it branches into the bronchi.
Step-by-step explanation:
The windpipe which conducts air between the larynx and lungs is called the trachea. The trachea, or windpipe, is a long tube that leads down to the chest and allows air to reach the lungs. After air passes through the larynx, it moves into the trachea, which then divides into the right and left bronchi.
The bronchi contain cartilage to keep them open and cilia to move mucus and trapped particles out of the respiratory system. These bronchi branch further into smaller passages known as bronchioles which end in tiny air sacs, the alveoli, where gas exchange occurs between the air and the blood.
