MICROANATOMY

Detailed explanation-1: -Your trachea divides into your left and right bronchi. The bronchi carry air into your lungs. At the end of the bronchi, the bronchioles carry air to small sacs in your lungs called alveoli.

Detailed explanation-2: -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-3: -In the mediastinum, at the level of the fifth thoracic vertebra, the trachea divides into the right and left primary bronchi. The bronchi branch into smaller and smaller passageways until they terminate in tiny air sacs called alveoli.

Detailed explanation-4: -The trachea is a midline structure and lies just anterior the esophagus. After it originates from the larynx, the trachea divides into the left and right mainstem bronchi. This junction point is called the carina.

Detailed explanation-5: -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. The left lung is a little smaller than the right lung because it shares space in the left side of the chest with the heart.
