Solution
The trachea, also known as the windpipe, is a tube that connects the pharynx and larynx to the lungs, allowing the passage of air. Before it reaches the lungs, the trachea divides into two smaller tubes called bronchi. Each bronchus then enters one of the lungs. So, the correct answer is "It branches in two directions."
