ANATOMY

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. The alveoli perform your body’s gas exchange.

Detailed explanation-2: -Your bronchial tubes lead to smaller air passages called bronchi, and then into bronchioles. The bronchioles end in tiny air sacs called alveoli, where oxygen is transferred from the inhaled air to your blood.

Detailed explanation-3: -The trachea branches into two smaller airways: the left and right mainstem [or main] bronchi.

Detailed explanation-4: -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-5: -The respiratory tract is divided into two main parts: the upper respiratory tract, consisting of the nose, nasal cavity and the pharynx; and the lower respiratory tract, consisting of the larynx, trachea, bronchi and the lungs.
