GENERAL HISTOLOGY

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: -The trachea divides into the two main BRONCHI (tubes), one for each lung. The bronchi, in turn, subdivide further into bronchioles. The RIGHT LUNG is divided into three LOBES, or sections. The left lung is divided into two LOBES.

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

Detailed explanation-4: -The left main bronchus departs from the trachea at a greater angle than that of the right main bronchus.

Detailed explanation-5: -Answer and Explanation: The structures in order from largest to smallest is B. Bronchi, bronchioles, terminal bronchioles, respiratory bronchioles, alveoli. Air moves through these airways in this order during inhalation to reach the alveoli, where oxygen participates in gas exchange with the blood.
