Detailed explanation-1: -Further down, the trachea divides into two tubes (left and right) called bronchi (BRAHN-kye). The bronchi connect the trachea to the lungs.

Detailed explanation-2: -Then your bronchi divide into branches that get smaller and smaller starting with: The lobar bronchi, which pass into a section (lobe) of your lungs. The segmental bronchi, which pass through a segment of each lobe.

Detailed explanation-3: -In your lungs, the main airways (bronchi) branch off into smaller and smaller passageways-the smallest, called bronchioles, lead to tiny air sacs (alveoli).

Detailed explanation-4: -The trachea divides into a right and left bronchi. Bronchi branch into smaller tubes that become bronchioles.

Detailed explanation-5: -The trachea (windpipe) is the largest airway. The trachea branches into two smaller airways: the left and right mainstem [or main] bronchi. Each lung is divided into sections (lobes): three in the right lung and two in the left lung.
